Reconciling b-theory with Aristotelian causality
Hey everyone,
Let me preface this by saying I have no formal education in philosophy, so please take that into consideration in your responses. I’m a long time lurker but I can’t seem to find the answer already having been articulated anywhere. I’m trying to understand how exactly under a b-theory of time, causality still exists either in the Aristotelian sense of actualizing potential or in any other theory of change and causality.
I’ve read a bunch of threads wherein people have said the vast majority of b-theorists do not at all deny that change exists, but I’m just struggling to understand exactly how change exists in a b-theory. When it is said that it is more about the properties of an object changing, how does that show that potentials are actualized if in a sense everything is already actual? Alexander Pruss is a b theorist and holds to Aristotelian concepts of change/causality and he states the following on his blog (alexanderpruss.blogspot.com/2019/06/is-eternalism-compatible-with.html?m=1 )
“A first answer is that a potential is actualized at a time t provided that its actualization exists at t. Thus, the potential is unactualized at t1 but actualized at a later time t2, because its actualization exists at t2 but not at t1. But, the objector can continue, by eternalism at t1 isn’t it the case that the actualization exists? Yes: but the eternalist distinguishes:
It is true at t1 that B exists.
B exists at t1.
Claim (11), for spatiotemporal objects, means something like this: the three-dimensional spacetime hypersurface corresponding to t?=?t1 intersects B. Claim (10) means that B exists simpliciter, somewhere in spacetime (assuming it’s a spatiotemporal object). There is no contradiction in saying that the actualization doesn’t exist at t1, even though it is true at t1 that it exists simpliciter.”
How can something exist “ simpliciter” in space time if all time past present future is already actual? How is anything simpler and then not simple if time is not objectively present and potentials aren’t actualized?
Thanks, sorry if some of this is not all that complicated and it’s just going over my head. I really appreciate it.

Within the sphere of traditional forms of interpretation of the manner in which time stands' to progress, as we hold it to be, there is a ceaseless shifting within its state, and a relative distinctness within each state that it may occupy. Whilst some have sought to demonstrate the fallibility of this conception, on the grounds that it appeals blindly to the precepts of mere intuition, those so concerning bear the ability to set forth an argument, in advocacy of the need for such simplicities of the understanding, to accord with all that is entrenched within the intuitive, and that by virtue of its content, may be apprehended readily, by any other. As it must conform to the basis of the experiential, and rendered intelligible with a faultless clarity by the faculties of mind, much value is evident in the case of its usage, if provided as an instrument in the exercise of cognition, for the understanding. A utility. Yet, one need recognize also, that these notions are in their nature, extraneous to the world, and thus without a sense of the objective in their appearance, and predication thereupon, in all instances.

Your difficulty in understanding arose from the substance of such notions as those described being fraught with many inconsistencies. When one is subject to the conflictive, and misconceived, for any great period, clearness in sight, and recognition of truth, is certain to faulter. I wish to implore you, for the sake of your own benefit, to ensure a greater depth of weariness of these things; lest your development of mind be stifled as well, in its entirety. For the insubstantial seldom proves conducive to growth, in any aspect of life.
First, I am not sure whether you are actually talking about the so-called B theory of time or about eternalism - these are not the same. According to the B theory of time, there is no objective matter of fact about the status of any particular moment of time as being past, present or future; objectively, there exist only relations between moments: prior to, simultaneous with and posterior to (setting aside relativistic complications for the time being...) According to eternalism, all things exist at all times (in some sense) - including things that are in our past or future at some given moment. These two claims are not convertible into each other, at least not without some additional assumptions. An A theorist (one who believes that past, present and future are objective properties of time) can very well be an eternalist, assuming they can make sense of things existing in the past or the future. It should be noted though that neither B theory nor eternalism are clearly defined with the glosses given above (nor would everyone agree that any clear definitions exist).
Second, I think that this potentiality vs. actuality business is peculiar to Aristotelian and Scholastic philosophy; you won't find much talk about "actualization of potential" in more modern accounts of causality (but I would welcome a correction). There may be tension between some modern theories of causality and eternalism and/or B theory, but I would hesitate to name one off hand.
Quoting jimmyjohns
I think you are misreading "simpliciter": here it just means "as is, without additional qualifications." In the context of the quoted text it means that B exists, but we are not saying that it specifically exists at time t1. For a presentist existence always implies existence in the present moment. An eternalist has to additionally index existence to a particular time. So for an eternalist saying "Socratest exists" (exists simpliciter) does not commit her to saying that Socrates exists now.
