Plato vs Aristotle (Forms/forms)

AJJ August 07, 2019 at 17:09 13475 views 109 comments
Are Forms and forms thought to be incompatible? Can’t material objects be manifestations of Plato’s Forms, while also having form as an essential metaphysical component as conceived by Aristotle? I don’t know their metaphysics well, but at a glance it seems to me that both accounts must (if they are at all) be true; my considerations being that in material objects matter and form are inseparable, and the forms that matter takes must (since both accounts posit a divine intellect) have existed prior to - and so also be separate from - their instantiations. Maybe this is all obvious, but it’s not clear to me why you’d adopt one view but not the other.

Because the forms exist within the divine intellect, which is eternal. From what I understand this is the case with both Platonism and Aristotelianism, but there might be an important distinction I’m not aware of.

Ah, so you're not arguing that in general, "the forms that matter takes must (since both accounts posit a divine intellect) have existed prior to - and so also be separate from - their instantiations," you're saying that per your understanding of both Aristotle and Plato, they both are basically asserting this?

If so, I misread you as changing scope for a moment, from a discussion of Aristotle and Plato per se to making a general comment outside of that context.

What I know about Aristotle I’ve learned from Edward Feser’s books, and about Plato from Dominic O’Meara’s introduction to Plotinus. Here’s something from the latter:

Given the existence of an intellect independent of the world (a position common to all Aristotelians and Platonists), this intellect must have itself as the object of its thinking. The point had already been made by Aristotle (Metaphysics, 12. 9)... Plotinus separates himself however from Aristotle when he claims that this self-thought in divine intellect is a thinking of the Forms.


But I don’t see the important difference if forms come from the divine intellect regardless.
luckswallowsall August 08, 2019 at 10:31 #314072
Aristotle was right: there is only one world. Or, at least, there's no evidence of Plato's Forms. Platonic Ideals are precisely that which we can have no evidence of—just as with Kant's Noumena—so I see absolutely no reason to believe in them.

But if you take Aristotle’s metaphysics to be true then you believe in the divine intellect, which is where the forms matter has come from, right? On Plato’s view, as interpreted by Plotinus anyway, the Forms exist within the divine intellect. To my limited understanding the difference appears to be a matter of emphasis.

The quote refers to material objects, not matter per se. Material objects is what I’m referring to as well.

I take these are your questions:
1) Are Forms and forms thought to be incompatible? 2) Can’t material objects be manifestations of Plato’s Forms, while also having form as an essential metaphysical component as conceived by Aristotle?

1) By whom? As in some applications - those in use here - they are terms of art. The the question then is unanswerable until and unless the terms are understood. But a hint and a clue suggests that as different terms, they mean different things, and as different things should be at least at first supposed incompatible.


So to answer the question someone could enlighten me to certain definitions that make the two views in contention incompatible.

Aristotle says many different things about matter, not all of it in agreement with other things he says about matter and form.


From one of the most influential commentators on Plato and Aristotle in the ancient world, Alfarabi. He had a strong influence on Aquinas.

Whoever inquires into Aristotle’s sciences, peruses his books, and takes pains with them will not miss the many modes of concealment, blinding and complicating in his approach, despite his apparent intention to explain and clarify.

– Alfarabi, Harmonization (unpublished translation by Miriam Galston,
quoted by Bolotin in Approach to Aristotle’s Physics, 6

This was the accepted view in the ancient world. For more see the section on Aristotle: https://www.press.uchicago.edu/sites/melzer/melzer_appendix.pdf

Perhaps you have a point, though I think what you’ve quoted there may be misleading. Here’s something else from the pages you linked to:

Philoponus (490-570), a Christian and largely a critic of neo-Platonism, seems in essential agreement with all of the preceding commentators:

“Now, [Aristotle] practiced obscurity on account of his readers, so as to make those who were naturally suited eager to hear the argument, but to turn those who were uninterested away right from the beginning. For the genuine listeners, to the degree that the arguments are obscure, by so much are they eager to struggle and to arrive at the depth.”

Then allow me to ask you, since you seem to know. What, in Aristotle, is matter? If a "component" is difficult to know, then so will be what it's a component of. We can leave this, if you like. I'm only on about the difficulty of the concepts, which neither the questions nor the references - except the Stanford.edu, - hint at.


This was discussed in Dfpolis’s thread on realism, and Feser talks of it in his book (matter per se is termed “prime matter”):

“since all cognition and every definition are through form, it follows that prime matter can be known or defined, not of itself, but through the composite” (DPN 2.14). The notion of prime matter is just the notion of something in pure potentiality with respect to having any kind of form, and thus with respect to being any kind of thing at all. And as noted above, what is purely potential has no actuality at all, and thus does not exist at all.


So matter is simply the potential for there to be a form instantiated in the world, as opposed to being a mere abstraction.

It is not that the concept is hard to grasp but rather that the concept shows itself to be problematic. If the school men interpreted it in such a way that there is no problem then perhaps they miss something or add something.

"prime" matter? Is prime matter different from matter?


“Prime matter” is to my understanding the term for matter apart from an instantiating form.

Quoting tim wood
That is, that matter, or prime matter - It - does not exist at all. And this is what I have seen represented as Aristotle's idea of matter - except that Aristotle apparently did not have a lot to say about matter, and such views are thus made up - inferred - from what he did say.


That’s fine I’d say; it’s appropriate to refer to those interpretations that lend the clearest insights.

Is the Scholastic view similar? In a much as the Scholastics held that universals possessed an extra-mental reality, it seem likely that they probably held that matter existed.


That definition I quoted is from a book on Aquinas, so I guess it is the Scholastic view.

Above as well we have the compatibility of The Forms, and form(s). If the forms are of the world, and The Forms are not, but are ideal and perfect, and the world is imperfect and imprecise, then how exactly are they compatible?


Sure, but what I don’t understand is why the forms on Aristotle’s view shouldn’t also exist perfectly in the divine intellect, where it seems they must originate.

Yes they are thought to be incompatible since Aristotle explicitly rejected Plato's theory of forms [*]. The difference is that Platonic Forms are independent of (or separable from) particulars whereas, for Aristotle, form and matter are correlates that are not separable from particulars.

Consider a typical abstract object such as a number or triangle. For Aristotle, these abstract objects are ultimately grounded in concrete particulars, not in a Platonic realm. As Aristotle wrote, "The best way to conduct an investigation in every case is to take that which does not exist in separation and consider it separately; which is just what the arithmetician or the geometrician does." (Aristot. Met. 13.1078a) [italics mine]

--

[*] As you are probably aware, there is much disagreement over what that rejection entailed. Some Neo-Platonist and Christian thinkers (such as Aquinas) argue that Aristotle didn't really (or fully) reject separability, with the unmoved mover and active intellect put forward as examples of this.

The world isn't grounded in the active intellect for either Aristotle or Aquinas. Both were realists about the world (which contained concrete particulars) and moderate (immanent) realists about universals. Aquinas says:

Quoting Thomas Aquinas and the Early Franciscan School on the Agent Intellect
It is necessary to postulate a power, belonging to the intellect, to create actually thinkable objects by abstracting ideas from their material conditions. That is why we need to postulate an agent intellect.


This SEP article on active intellect is also useful and highlights the nature of the controversies. Regarding interpretation, "The first and most consequential fault line, then, concerns whether De Anima iii 5 should be taken as characterizing the human mind or the divine mind." As indicated above, Aquinas argued for the "human mind" view.
Wayfarer August 11, 2019 at 08:42 #314775
Quoting Andrew M
For Aristotle, these abstract objects are ultimately grounded in concrete particulars, not in a Platonic realm.


I think the question would have to be asked, then, why Aristotelian philosophy is not nominalist. Because nominalism denies that 'forms' or 'types' have any reality outside the things which instantiate them; nominalism means 'name only'. So we call something a triangle because it happens to have three sides comprising straight lines that intersect; there is no triangle other than specific instances of triangles. But the very reason we can recognise a triangle, or a circle, or what have you, is because it obeys the requirements of a particular form - that it is a flat plane bounded by three intersecting lines, or a line drawn by points equidistant from a centre, and so on.

So there, the 'form' is truly 'an idea', not simply the shape of something, but the defining feature - the essence, if you like, which is what is perceived by the rational intellect.

[quote=Kelly Ross]Aristotle "immanentized" the Forms. This meant, of course, that there still were Forms; it was just a matter of where [or in what sense ~ WF] they existed. So Aristotle even used one of Plato's terms, eîdos, to mean the abstract universal object within a particular object. This word is more familiar to us in its Latin translation: species. In modern discussion, however, it is usually just called the "form" of the object.

The Aristotelian "form" of an object, however, is not just what an object "looks" like [in other words, not just it's shape ~ wf]. An individual object as an individual object is particular, not universal. The "form" of the object will be the complex of all its abstract features and properties. If the object looks red or looks round or looks ugly, then those features, as abstractions, belong to the "form." The individuality of the object cannot be due to any of those abstractions, which are universals, and so must be due to something else. To Aristotle that was the "matter" of the object. "Matter" confers individuality, "form" universality. Since everything that we can identify about an object, the kind of thing it is, what it is doing, where it is, etc., involves abstract properties, the "form" represents the actuality of an object.[/quote]

http://www.friesian.com/universl.htm

“EVERYTHING in the cosmic universe is composed of matter and form. Everything is concrete and individual. Hence the forms of cosmic entities must also be concrete and individual. Now, the process of knowledge is immediately concerned with the separation of form from matter, since a thing is known precisely because its form is received in the knower. But, whatever is received is in the recipient according to the mode of being that the recipient possesses. If, then, the senses are material powers, they receive the forms of objects in a material manner; and if the intellect is an immaterial power, it receives the forms of objects in an immaterial manner. This means that in the case of sense knowledge, the form is still encompassed with the concrete characters which make it particular; and that, in the case of intellectual knowledge, the form is disengaged from all such characters. To understand is to free form completely from matter.

Moreover, if the proper knowledge of the senses is of accidents, through forms that are individualized, the proper knowledge of intellect is of essences, through forms that are universalized. Intellectual knowledge is analogous to sense knowledge inasmuch as it demands the reception of the form of the thing which is known. But it differs from sense knowledge so far forth as it consists in the apprehension of things, not in their individuality, but in their universality.

The separation of form from matter requires two stages if the idea is to be elaborated: first, the sensitive stage, wherein the external and internal senses operate upon the material object, accepting its form without matter, but not without the appendages of matter; second the intellectual stage, wherein agent intellect operates upon the phantasmal datum, divesting the form of every character that marks and identifies it as a particular something.

“Abstraction, which is the proper task of active intellect, is essentially a liberating function in which the essence of the sensible object, potentially understandable as it lies beneath its accidents, is liberated from the elements that individualize it and is thus made actually understandable. The product of abstraction is a species of an intelligible order. Now possible intellect is supplied with an adequate stimulus to which it responds by producing a concept.



~From Thomistic Psychology: A Philosophical Analysis of the Nature of Man, by Robert E. Brennan, O.P.; Macmillan Co., 1941. (Additional paragraphing and emphasis added).

https://thomasofaquino.blogspot.com/2013/12/sensible-form-and-intelligible-form.html

Aristotle, in De Anima, argued that thinking in general (which includes knowledge as one kind of thinking) cannot be a property of a body; it cannot, as he put it, 'be blended with a body'. This is because in thinking, the intelligible object or form is present in the intellect, and thinking itself is the identification of the intellect with this intelligible.

Among other things, this means that you could not think if materialism is true… . Thinking is not something that is, in principle, like sensing or perceiving; this is because thinking is a universalising activity. This is what this means: when you think, you see - mentally see - a form which could not, in principle, be identical with a particular - including a particular neurological element, a circuit, or a state of a circuit, or a synapse, and so on. This is so because the object of thinking is universal, or the mind is operating universally.

….the fact that in thinking, your mind is identical with the form that it thinks, means (for Aristotle and for all Platonists) that since the form 'thought' is detached from matter, 'mind' is immaterial too.

I’ve been confusing terms - I thought the active intellect was another way of describing the unmoved mover. So it seems to me on Aristotle’s view that universals must be ultimately grounded in the unmoved mover, rather, which is why I don’t fully understand the rejection of Plato’s Forms.

It's better to look at matter as the potential for change. The concept of "matter" is introduced by Aristotle as a means for understanding the nature of change. If a thing has one form at one moment, and a slightly different form at the next moment, we say that the thing has changed. If "the thing" is identified strictly by its form, then at one moment it is not the same thing as it is at the next, due to it's changing. So in his Physics, Aristotle wanted to be able to explain what we all observe, and say, that a thing remains being the same thing despite the fact that there are changes to it. Matter is the underlying thing which persists, and does not change when a change occurs, and assuming the reality of matter allows us to say that the same thing persists from one moment to the next, but it changes.

I say it is "the potential for change", because it is what has been determined by Aristotle as what is required (logically) to make change into something real, something comprehendible. If we can state the form of a thing (describe what it is) at one moment, and do the same at a following moment, and see that the form is slightly different, then we ought to be able to account for the change to the thing which happens between these moments. If we account for the change by stating an intermediate form, which is different from the other two, this does not solve the problem because now we have changes between this form and the others. We cannot posit an infinite number of forms between one form and the next, to account for change, so Aristotle posits matter. Matter is not a form, but it provides the potential for one form to change into another, with the thing remaining as the same thing. Matter is what makes becoming intelligible.

Aristotle's concept of hyle is the principle that correlates with eidos (form) and this can be demonstrated in the way the philosopher described hyle, saying it is that which receives form or definiteness, that which is formed.[5] Aristotle explained that "By hyle I mean that which in itself is neither a particular thing nor of a certain quantity nor assigned to any other of the categories by which being is determined."[4] This means that hyle is brought into existence not due to its being its agent or its own actuality but only when form attaches to it [ I would prefer 'is given form']. ...

...

The Latin equivalent of the hyle concept - and later its medieval version - also emerged out of Aristotle's notion. The Greek term's Latin equivalent was silva, which literally meant woodland or forest.[4] However, Latin scholars opted for a word that had technical sense instead of the literal meaning so that it became understood as that of which a thing is made but one that remained a substratum with changed form.[4] The word materia was chosen instead to indicate a meaning not in handicraft but in the passive role that mother (mater) plays in conception.


My bolds. I had read previously that 'mother' and 'matter' were etymologically related but never knew how.

Another point: that Aristotelian dualism comprised 'matter and form', not the Cartesian 'matter and mind'. However I think Descartes' version was ultimately derived from the same source, albeit Descartes wished to sharply differentiate his philosophy from that of 'the schoolmen'.

Beyond that is arguing whether the largest number of angels that can fit on the head of a pin is an even or an odd number.


I read about 'angels on the head of a pin' recently. It's held up as an example of the vanity of scholastic metaphysics. But the real debate was about 'whether two incorporeal intelligences (i.e. 'angels') can occupy the same spatial location - which is not that daft a question at all, although of course in a materialist culture, the whole notion of 'incorporeal intelligence' is unintelligible. (That said, there's an echo of the same question in the conundrums surrounding superposition.)

ON the contrary, I think it is quite useful to trace how Aristotelian (and other classical) terms and ideas, like 'hyle', 'ousia', 'esse', and so on, have been translated and interpreted over time.

Sure, it’s what allows there to be material objects in the first place and also what allows them to change.

Quoting Metaphysician Undercover
So in his Physics, Aristotle wanted to be able to explain what we all observe, and say, that a thing remains being the same thing despite the fact that there are changes to it. Matter is the underlying thing which persists, and does not change when a change occurs, and assuming the reality of matter allows us to say that the same thing persists from one moment to the next, but it changes.


I don’t understand the above though. Since matter isn’t composite, doesn’t that mean the same matter underlies every object? In which case the only way to distinguish between objects is by their forms; but why then do individual objects remain the same objects as their forms change?

Plato described matter in Timaeus in sexist terms, coming from ancient myths. It is a passive principle which receives the form, like being impregnated. Notice also the duality in "conception". Plato plays with that duality in Theatetus, when Socrates refers to himself as a midwife.

The issue of the intellect receiving the form of the object, in conception, becomes a difficult question for Aquinas. In order to receive the form of an object, the intellect must have a passive aspect. The passive aspect is a potential, like matter, but Aquinas wants to maintain the immaterial essence of the intellect, and I think he refuses to refer to this passive aspect as material in nature. The way I understand this issue is that the intellect is essentially immaterial, but it has material accidentals. The accidentals are what individuate us as distinct, separate, and unique human beings.

Quoting Wayfarer

What Aristotle does, which is not as evident in Plato (except perhaps Timaeus), is extend the duality of reality into all things, all objects, not just human beings. Notice that Descartes brings us back to the primitive form of dualism, similar to the dualism expressed by the myths described by Plato. Plato demonstrated how difficult it is to make sense of this dualism. From this position, where dualism is extremely difficult to make sense of, we have the choice of two distinct directions. We can dismiss dualism as simply incoherent (as is the modern trend), or we can follow a system like Aristotle's, which extends dualism into all aspects of reality. I find that the cosmological argument is very important because it demonstrates very forcefully, and decisively, that the only rational way to proceed is to extend dualism.

To those others discussing "prime matter", the cosmological argument denies the possibility that the concept of prime matter could refer to anything real.

This is a good question, and I think that the best way to proceed is to understand "matter" as an assumption. Aristotle assumed "matter" as the principle of continuity of existence. Ultimately, it accounts for the fact that the world cannot be randomly different from one moment to the next. Newton characterized this as inertia. I understand matter as the continuity of time itself. Modern physics now uses "energy" (conservation of energy), to refer to that which remains, or persists, through change, this allows the principle of continuity to cross between one object and another, such that the continuity of an object is no longer assumed in physics, as it is in Aristotelian physics.

From the first paragraph you quoted earlier:

The traditional interpretation of Aristotle, which goes back as far as Augustine (De Genesi contra Manichaeos i 5–7) and Simplicius (On Aristotle’s Physics i 7), and is accepted by Aquinas (De Principiis Naturae §13), holds that Aristotle believes in something called “prime matter”, which is the matter of the elements, where each element is, then, a compound of this matter and a form. This prime matter is usually described as pure potentiality

You are right to point to the problems with what Aristotle says about matter. But I think he was smart enough to recognize that it is problematic. In fact, I think that is exactly where he leads the thoughtful reader. He, like Plato and Socrates, is a zetetic skeptic (not to be confused with modern versions of skepticism). We simply do not know and so cannot say what 'is' at the most fundamental level.

Of course, this does not stop people from making such claims. So, it is better he tell his own stories, reasonable stories, beneficial stories.

The quotes in this post are all exactly about that, and, I must confess, make perfect sense to me.


I mostly agree with what's in those quotes, except this:

Kelly Ross:The individuality of the object cannot be due to any of those abstractions, which are universals, and so must be due to something else. To Aristotle that was the "matter" of the object. "Matter" confers individuality, "form" universality.


Aristotle actually distinguishes two primary senses of "form", the form which we grasp, the universal, or the essence of the thing, and the form of the particular. The form of the particular includes all the accidentals, which are left out from the essence. We do not grasp the entirety of the thing's form. So it is not matter which confers individuality, it is form, but it is the property of a material thing, to be an individual. We have in Aristotle a distinction between form as essence, abstraction, or universal, and the form of the particular, material thing.

It is in understanding that each individual object has a distinct, and unique form, that you may come to realize that the form of a particular object is necessarily prior to the material existence of that particular object. This is one way that we come to see that form is prior to material existence. Material objects come into being. When a thing comes into being, it must be the thing which it is, and not something else. It is impossible that a thing is other than itself, by the law of identity. Further, a thing is an ordered unity, it is not random. By these two premises, it is necessary to conclude that what the thing is (its form) precedes its material existence.

Quoting AJJ

Sure, but for Aristotle prime matter, or pure potentiality, is incoherent, unintelligible, a logical impossibility by the cosmological argument. Simply put, a potentiality requires an actuality to be actualized. If there ever was a time when there was pure potential, there would be no actuality at that time, and therefore the potential could not ever be actualized, so there would always be pure potential with no actuality. However, we observe that there is actuality, so it is impossible that there ever was pure potentiality.

Quoting AJJ
So this is where I like Platonism: the notion that there is an organising principle (Soul), which fashions the world after the Forms. That way it seems an object remains the same object throughout changes so long as it’s participating in the same Forms.


The problem with the theory of participation, which Plato uncovered, and becomes evident from The Republic on, into his later work, is that the thing which is participated in is passive, as the thing participating is active. What Plato discovered, and this constitutes his proposal of "the good", is that in order for the Forms to have any real participation in the real world, they must be active, actual. He found this principle of action in "the good". We act for what we perceive as the good, and the Ideas, or Forms are directed towards the good, such that they receive actuality in this way, from the good.

This is why the philosopher in the cave turns things around, realizing that what the people in the cave see as reality, the material objects, are really reflections, representations of the Forms, which are actively causing the existence of material objects, which the cave people take as the totality of reality. So a material object does not participate in the Forms, the Forms actively cause the existence of the thing by informing the matter. This makes matter the passive aspect of reality, while Forms may participate in passivity by remaining the same, and having the potential to change.

Quoting tim wood
What is it he says explicitly matter is?


Is this a trick question? The whatness of a thing is the thing's form. Matter is distinct from form. So it makes not sense to ask "what is matter", because asking "what", is asking for a form. If someone tried to tell you what matter is, they'd be handing you a form, saying "this is matter".

Those quotes I referred to make a very clear point: the material senses (eyes, ears) perceive the particular being, the intellect perceives the form. The material thing must always, of necessity, be apart from us - in modern terms, an object to us, something outside of us. But 'the form' is known directly by nous, as the form is basically an idea, not a thing. That is the 'rational intellect' in operation.

(2) I think it's a common mistake to equate 'form' with 'shape'. The 'form' is not 'the shape' (or even 'what something appears to be'). The form is 'the type of thing it is'. We recognise a [chair/apple/tree/triangle] because we know the meaning of the concepts, what it is that gives the object its identity. It's partially shape or appearance, but it's something much more than that.

I think you're mistaken, but at least here, we can be very clear about the confusion, which should be instructive.

My thought is that there is no 'form of the particular' because 'forms' by definition are *not* particular but universal. Read this passage again: 'The proper knowledge of the senses is of accidents, through forms that are individualized; the proper knowledge of intellect is of essences, through forms that are universalized.' And 'a particular being' is precisely a combination of accidents and universals, of (individualised) matter and (universal) form. Hence, hylomorphic, matter-form, dualism.

Socrates is of the [form or type] Man, but happens to have flat nose, etc, which pertain to him as an individual. It is 'the accidents' which confer individuality. But insofar as Socrates is a man, he is a form, or a universal.

The Neo-Platonists, like Plotinus use a different conception of participation than the one Plato described derived from the Pythagoreans.

The senses, and the intellect are both powers of the soul. They both perceive a form. "Form" refers to what a thing is. The senses perceive the form of the particular (though this perception is deficient), while the intellect may apprehend the essence, which is the universal form. So for instance, through my senses I perceive the form of the particular object in front of me, my laptop, but this perception of the object is deficient, because I am only actually perceiving certain aspects of the form, its shape, colour, etc.. At the same time, my intellect apprehends the form of the thing in the sense of "laptop", recognizing the essence of the thing as a laptop.

Quoting Wayfarer
The form is 'the type of thing it is'.


Aristotle is very clear on this point, form refers to whatness, (I think it's called quiddity) what a thing a thing is. He starts with "form" as the type of thing, but proceeds to examine "form" in the sense of the individuality of a thing. This is made necessary by his law of identity which he proposed as a law against sophism. The sophist could claim that two things which are the same type, are actually the same thing. So the law of identity designates that two distinct things which appear to be the same (are the same type) cannot actually be the same thing. Since they are in fact distinct, there must be some formal aspects which distinguish one from the other. Remember, the intellect only apprehends form, so the distinction between two things must be formal if the intellect is to be able to grasp it.

Individual particular objects have a form proper to themselves. You'll see that this is one of the main topics Aristotle investigates in his Metaphysics, where he investigates being qua being. He dismisses the commonly quoted "why is there something rather than nothing", and poses instead, the question of "why is there what there is instead of something else". So this question becomes why is a particular object what it is, and not something else. This is because it is given a particular form. He's very specific on this point, a particular thing has a form unique to itself.

I think if you read more you'll find it very clear that Aristotle proposed a form of the particular. "Accidents" are formal, part of a thing's form, they are just not part of a things essence.

Aristotle's use of common words always maintain that usage even when he extends the meaning. The term 'eidos' means the look or kind or essence or species of a thing. Form is also the term used to translate 'morphe'.

I do not think that Aristotle's aim is to provide a consistent definition of the term but to examine what is said and observed. That is why he typically begins by discussing earlier philosophers. He is not building arguments that lead to clear unambiguous conclusions and knowledge. He is leading the reader to think about these matters, to recognize that they are problematic, aporetic.

Prior to the existence of a thing, is the potential for that thing. But the potential for that thing exists as something actual, so this potential is not "pure", it is restricted by what actually exists. Pure potential would be infinite, and this is what is impossible to conceive of as being real. It can't be real, because as I said this would mean that at this time, when there was infinite potential there would be nothing actual. And if there was nothing actual, there would be nothing to actualize anything out of that potential, so there would always be nothing actual. But this is inconsistent with our observations that there is something actual. That's why it's impossible to conceive of, because it requires that nothing is actual.

That's right, there is no principle which we can say "necessitates" material existence. One Form necessitates another Form, through a logical process (logical necessity), but no Form can necessitate material existence. This is an indication that material existence is caused by an act of free will, the love of God, or because God thought it was good.

And btw, the "what" referred to what Aristotle says about matter. It's right there above: "What is it he says...? So the question stands: what does he say about it?


Actually tim, you said: "What is it he says explicitly matter is". This is asking what Aristotle said matter "is". AJJ answered that very well, with "potential". Potential neither is (being) nor is not (not being), that's why it is proposed as a means of accounting for the reality of becoming And since "potential" is other than "actual", and this is what "is" refers to, what is actual, it really doesn't make any sense to ask what matter is. Now you've changed the question to what Aristotle says "about" matter, and this is a whole lot of different things, in a whole lot of different places, and that's why your quotes from Stanford show such a variance. When we say "what" a thing is, we generally state some sort of definition. But when we talk "about" something we tend to say many different things about it, and it is not necessary that "what it is" is one of the things that we say about it. So we might entertain the possibility that there could be something (like matter), which has no "what it is".

As a matter of the history of ideas, his conclusions are interesting. But they're not modern science. As noted above, his "matter" is that which not only isn't, but isn't even an isn't, and cannot even be asked about. it's a plug-placeholder for a problem that Aristotle encountered in giving an account that he did not solve and that he knew perfectly well that he did not solve.


Of course he knew perfectly well that he didn't solve that problem (the problem of becoming), he proposed some principles, and a direction to move in. I don't see the point in your comparison to modern science. Physicists know perfectly well that they have not solved this problem either. Modern physics points us in a direction slightly different from that proposed by Aristotle. The fundamental particle "isn't", but this isn't isn't even an isn't, because the fundamental particle is something, it's a wave. OK, I see the point to your comparison. But since neither solves the problem, on what basis would you claim that one is wrong?

I’ve been confusing terms - I thought the active intellect was another way of describing the unmoved mover.


While they are given independent accounts in Aristotle's writings, some commentators do consider them to be equivalent and that is one of the interpretive controversies.

So it seems to me on Aristotle’s view that universals must be ultimately grounded in the unmoved mover, rather, which is why I don’t fully understand the rejection of Plato’s Forms.


Aristotle rejected Plato's theory of forms and replaced it with his own hylomorphic theory. But per Aristotle's description, the unmoved mover doesn't seem to be a hylomorphic or natural being. Which puts the unmoved mover in apparent tension with Aristotle's otherwise consistent hylomorphism and naturalism. So interpretation here is also controversial with different commentators providing a range of Platonic and naturalist accounts.

My own view is that the unmoved mover should be understood in terms of Aristotle's hylomorphism and naturalism and not in Platonic terms. That would be consistent with his rejection of Plato's forms.

No, it is Aristotle's immanent realism that denies that 'forms' and 'types' exist in separation from particulars (though they can be considered separately).

Whereas nominalism denies that 'forms' or 'types' have any reality outside the people that name them. Ockham wrote, "I maintain that a universal is not something real that exists in a subject ... but that it has a being only as a thought-object in the mind".

Pure potential would be infinite, and this is what is impossible to conceive of as being real. It can't be real, because as I said this would mean that at this time, when there was infinite potential there would be nothing actual.


Yeah, I see what you’re saying now and agree. To conceive of prime matter is to conceive of non-existence existing, which of course you can’t.

Aristotle was a student of Plato, he was not educated in modern naturalism.


For Aristotle, knowledge comes from experience in the natural world.

Quoting Aristotle - Wikipedia
Aristotle's immanent realism means his epistemology is based on the study of things that exist or happen in the world, and rises to knowledge of the universal, whereas for Plato epistemology begins with knowledge of universal Forms (or ideas) and descends to knowledge of particular imitations of these.

My own view is that the unmoved mover should be understood in terms of Aristotle's hylomorphism and naturalism and not in Platonic terms. That would be consistent with his rejection of Plato's forms.

I like the Aristotelian emphasis on the material, as opposed to the Platonic notion of the world being something we must ascend from; but I’m inclined also to think the world is an imitation of things higher than it - seems there’s enough ambiguity to hold to both approaches.

After some consideration, I choose not to play water-polo with you in your pool. Aristotle is your subject. As to matter, my only point has been that whatever the jr. high school science teacher means by "matter," it is not in any way or sense what Aristotle meant. As to presuppositions of Aristotle, I feel no need to list them. They're there in Stanford.edu, such as they are. In any case he was not a modern scientist. He observed and tried to make sense. A modern scientist asks questions and does experiments to find answers.


Yes I would agree with all that. That Aristotle was not a modern scientist is a rather obvious and trivial point, unless perhaps someone here thought he was, then there might be a need to point that out.

Mainly it is significant thinking in the history of thinking.


What exactly does this mean to you, "significant thinking in the history of thinking"? Suppose that someone thinks, and comes up with some influential ideas. Would this constitute significant thinking in the history of thinking? Does this put Aristotle in the same category as someone like Einstein?

Earlier you said "The history of ideas shouldn't be confused with ideas in themselves." What does this mean? How would you propose to create a separation between an idea and the history of that idea? An idea has a temporal presence, an extension in time. Doesn't it appear to you, that to describe an idea is to describe its extension in time, its influence on people through time, how different people understand the same idea, etc.. What do you think would be 'the idea itself'? Consider the example of Einstein's general theory of relativity. The history of that idea would be how different people interpreted it, applied it, and the effects that it had on the people in general. What would be the idea itself? Suppose you tried to tell me what the idea of general relativity is. Wouldn't that just be an expression of how the idea affected you, and therefore just a small part of the history of that idea?

In brief, it means that, for example, studying what people have done and thought is usually helpful to current effort.

So long ago I do not remember the particulars, an economist addressed the challenge of new manufacturing in countries that did not have good manufacturing and wanted it. This question (c. 1962?) was, why don't countries without good manufacturing just buy "stuff" and copy it, maybe improving it in the process?

By way of answer, the author noted that BMW made excellent motorcycles. The Soviets (as I recall) had bought several and taken them apart on the assumption they had merely to copy and make. They made, they ended up with, the Ural. A look-a-like motorcycle, but in quality as a horse chestnut is to a chestnut horse (thank you Mr. L.). The idea was that in order to have good manufacturing, you have to travel at least most of the path to get there. To learn to make good tools, have good steels, make good plants - a problem of its own - have skilled labor and technicians and management, and on and on. That is, copy and make just is not that simple.

In the same way, the history of philosophy - the history of ideas - is at least as valuable. I've read it - if I could cite I would - that philosophy just is the history of philosophy. Call it the propaedeutic part.

As to the rest of the latter part of your remark, that's too much deconstruction for (my) present purpose.


Sorry Tim, but I just can't understand what you're trying to say here.

Quoting tim wood
"... just be an expression of..."? Isn't that both minimalist and reductionist beyond sense? It implies that idea is based in a mind and has no independent existence. Granted that people can express ideas in different ways, but the idea itself, to stand as an idea, must have something constant in it independent of either yours or my twist of it. You may have feelings about two plus two equaling four, but they don't touch it, yes?


What do you mean by "the idea itself"? And how does an idea "stand as an idea"? Isn't an idea dependent on a mind? Do you think that an idea can stand alone out in a field, like a horse? We have books, and written material which maybe could be considered to stand alone, as representations of ideas, But to refer to the idea itself, wouldn't this be referring to what the mind produces from the reading and understanding of the book? And this is in a mind. What do you think is this "constant" thing? I believe that my understanding of two plus two equaling four is similar to your understanding of this, but similarity is not the same as "constant thing".

:up:

The whole point about Platonic idealism, and even Aristotelian realism, is that there is a sense in which ideas are real in their own right. They're not real by virtue of being 'patterns of neural activity' which is the almost irresistible way of thinking about them we nowadays have. They can be best understood as the organising principles by which we make sense of reality - the principles of intelligibility, if you like. I refer frequently to Augustine on Intelligible Objects by way of explanation. This entry on objective idealism is also useful.

Arguably the human brain given its methods of perception has itself evolved into a cognizing organ of very great sensitivity to the world it finds itself in - or more accurately, to the world as it perceives it. Were we whales or porpoises or squid, or had we thousands of eyes like a fly, or if like May flies we lived a day, or some other things that live very long times, or if we were just plain a lot different that we are, then likely we would have very different ideas of our world.


Right - so basically a Darwinian account, that mind is the product of an evolved brain, and the brain a product of the evolutionary process. That is what almost every accepts, but I question it on the basis that at a certain point in evolutionary history, we became language-using, rational beings - and thereby transcend the biological, so to speak.

There’s an interesting dialogue between Einstein and Ravindranath Tagore, Hindu poet and mystic. Worth reading. But it contains this paragraph:

EINSTEIN: I cannot prove scientifically that Truth must be conceived as a Truth that is valid independent of humanity; but I believe it firmly. I believe, for instance, that the Pythagorean theorem in geometry states something that is approximately true, independent of the existence of man.


The question I would have asked Einstein is, who knows this other than man? It is a fact that can only be grasped by a rational intellect. So, yes, it’s independent of your mind or mine; but it is an intelligible, rather than a material, object. And we construct our ‘meaning-world’ around such principles.

Disappointed in that remark. I am of the view that such figures as Socrates and the Buddha were historical persons, and were possessed of real wisdom. What happened in Western history, was an undue emphasis on belief in or acceptance of religious dogma (especially in Protestantism); but there’s far more to it than simply the acceptance or rejection of dogma.

Cats communicate. Dogs communicate. The news is full of stories of animals that communicate.


But I think their communicative abilities can be understood in terms of behaviourism, stimulus and response. Certainly animals signal each other, bee dances, and whatever. But...

...human language involves the capacity to generate, by a recursive procedure, an unlimited number of hierarchically structured sentences. A trivial example of such a sentence is this: “How many cars did you tell your friends that they should tell their friends . . . that they should tell the mechanics to fix?” (The ellipses indicate that the number of levels in the hierarchy can be extended without limit.) Notice that the word “fix” goes with “cars,” rather than with “friends” or “mechanics,” even though “cars” is farther apart from “fix” in linear distance. The mind recognizes the connection, because “cars” and “fix” are at the same level in the sentence’s hierarchy. ...

Animal communication can be quite intricate. For example, some species of “vocal-learning” songbirds, notably Bengalese finches and European starlings, compose songs that are long and complex. But in every case, animal communication has been found to be based on rules of linear order. Attempts to teach Bengalese finches songs with hierarchical syntax have failed. The same is true of attempts to teach sign language to apes. Though the famous chimp Nim Chimpsky was able to learn 125 signs of American Sign Language, careful study of the data has shown that his “language” was purely associative and never got beyond memorized two-word combinations with no hierarchical structure.

A mind? How about minds?

Or maybe you're just arguing that in the whole entire history of the universe every single instant that ever was or ever will be is unique. Not only can you not step into the same river twice, you cannot even once. Is that where you're going? And every thing, which requires continuity, is just a dream, because nothing is the same from moment to moment. - wait! not even in dreams! Is that where you're aiming?


I'm not arguing anything here, I'm just trying to get some clarification of what you mean. You say things which do not make sense to me. For instance, why do you say "minds" instead of "mind"? I can have an idea in my mind, which does not seem to be dependent on any other minds, so why would you jump to this conclusion that ideas are dependent on minds, not on a mind?

Isn't it true that every instant of time in the history of the universe is unique? That seems very obvious, once something has happened we cannot go back to how things were before. Why would I need to argue this? Where do you get the idea of "continuity" from? We observe that some aspects of reality stay the same even as time passes. Aristotle posited matter as the principle of continuity, to account for the reality of what is observed. Newton took matter for granted, as the substance of "a body" and gave matter the property of inertia (continuity); Newton's first law. You seem to think that this idea is wrong, and ought to be replaced by a modern conception of "matter", how so?

In the Augustine citation almost the first qualification that meets the eye is "...must be independent of particular minds...".

I buy the notion that no mind(s) at all, then no ideas. Plenty to think about, but no one to do the thinking, or even to think about the possibility. But given minds, you get something like Mind, the collective and dynamic wisdom of..., that as history plays out, ebbs and flows, and has its spring and neap tides, its seasons of flood and drought.

A difficulty I have with any notions of being-less minds being the author and communicator to us of reality-as-we-perceive-it, is that the people who themselves create such theories do it to give an account, and the only account they can think of, of what we perceive and how we perceive it. In every case they simply do not have access to any understanding of the history of the development of mind - brain - itself over, what, most of five-hundred-million years? Maybe four hundred million?

Arguably the human brain given its methods of perception has itself evolved into a cognizing organ of very great sensitivity to the world it finds itself in - or more accurately, to the world as it perceives it. Were we whales or porpoises or squid, or had we thousands of eyes like a fly, or if like May flies we lived a day, or some other things that live very long times, or if we were just plain a lot different that we are, then likely we would have very different ideas of our world.

So what I find in most ancient philosophies and religions - and imo all religions are ancient, even the modern ones, is the attempt to make sense, but with the only recourse to make the sense being non-sense - and a credulous audience. Unfortunately credulity too is both an ancient and a modern trait, with some excuse for them, and not-so-much or hardly any at all for us.

Of course this Mind in question is human mind, its wisdom, as opposed to knowledge, mainly in good and astute psychology. But this won't do at all for either of the myth-ifiers or the mystifiers. Just leaves the question if we will survive them.


There's a deep inconsistency here. Let's take the assumption that an idea is dependent on minds, and cannot be produced, nor maintained simply by the single mind of an individual human being. Because of this assumption you are forced to jump to "Mind", which is supposed to represent some sort of collective mind, as this is what is required to support the existence of ideas. But then you belittle this Mind by saying "this Mind in question is human Mind". Do you see the inconsistency? A human mind is a particular mind of an individual human being. If you assume some sort of collective Mind, it is impossible that this is a human mind. The assumption of a collective Mind is not so easily supported as you make it sound.

This I neither thought nor said. What I mean is that there are individual minds, "and given minds, you get something like Mind." Offhand I'd agree that ideas - the content of them - originate in one mind, or a few working together - I suppose one must always be first. But as the knowledge becomes generally known, it becomes a community possession. No special mystery here.


There's no mystery here, only an invalid conclusion. The point, is that many human minds does not make a "Mind". That's like saying many horses makes a "Horse". There's no justification for such a conclusion. No matter how many human beings with minds you put into the same room, they do make a Mind which is human, but which is not a human mind. You've inverted subject for predicate by pluralizing, such that a number of human beings with minds becomes a Mind which is human. How could you possibly justify such an illogical maneuver?

— Andrew M

Interesting to consider how that might work.


So Aristotle gives a concrete example in Physics Book 8 where he describes a man who moves a stone with a stick.

Consider this in terms of a golfer hitting a golf ball with a golf stick. The golf stick is the moved mover of the golf ball (the efficient cause). In turn, the golfer's hand is the moved mover of the golf stick. But what causes the golfer to move his hand? Aristotle identifies a different kind of cause - a final cause. The golfer moves his hand because he desires to play golf. Thus he is the unmoved mover that causes the golf ball to move.

But note also that the golfer's hand moves, which is a part of his body. So he is the compound of a moved mover and an unmoved mover (in different causal senses). In this scenario, it is the "unmoved mover" explanation that finally grounds the golfer's activity. It is this intentional aspect of the golfer (his purposes, thoughts and desires) that explains the motions of the golfer, golf stick and golf ball throughout the game.

That is the kind of concrete and observable scenario that Aristotle generalizes from to explain all activity (or change) in the universe as by an unmoved mover in terms of final cause. In both the specific and universal contexts, the locus of causality (in terms of Aristotle's four causes) are the natural particulars.

Don't try to turn the table, you are the one making the illegitimate reification, talking about this Mind, as if it is a real thing. If it's not a real thing, then what are you talking about other than a group of human beings, each with one's own mind?

So, it's up to you to tell me, what are you talking about, a real thing called Mind, or real individual human minds. You talk about "Mind" as if it is something other than individual human minds, and when I point out that's nonsense, you say you weren't talking 'mind' as is it's a real thing. What were you talking about then, a bunch of individual minds? I think so. So stop calling this group of minds "Mind" if there's no such thing as Mind.

I've never heard of such a thing as the "American mind". You're still talking nonsense. Freedom is not something that inheres in a mind, unless you are talking about free will.

It is just classifying similar ways of thinking.

Saying "all human beings have a mind" doesn't justify talking about "a Mind which all human beings have", just like saying "all grass is green" doesn't justify saying "there is a Green which all grass has".
