If a science fiction adventure is being talked about, the science fiction adventure must exist somewhere, whether as print in a book, in the mind of t...

There is no one definitive version of the PSR. You interpret the PSR as saying that every event, known or unknown, must have a reason. I don't believe...
December 13, 2024 at 17:43
There is no one version of the PSR. There are different formulations. The PSR is a family of principles (SEP - PSR). For Leibniz, God knows all events...

Yes, if the first even prime greater than 100 didn't exist, you couldn't be writing about it. But you are writing about the first even prime greater t...

If numbers didn't exist, then you couldn't be writing about them, so they must exist somewhere.
December 13, 2024 at 09:09
There are different formulations of the PSR. You cite one version of it. See SEP - Principle of Sufficient Reason. ===================================...
December 13, 2024 at 08:33
You propose a formulation of the PSR that states that for everything, whether known or unknown, there must be a reason. You must feel that there is a ...
December 12, 2024 at 16:40
You defend the PSR, in that for any thing that exists or is true there is sufficient reason. You also give the examples of things that don't have a su...
December 12, 2024 at 09:57
For Leibniz, God knows all events whether known or unknown by humans. Can you justify your statement above, in that if an event is unknown to humans t...
December 12, 2024 at 09:31
No, I am arguing that the PSR cannot be applied to unknown events I am arguing that it is not possible to know about something that we don't know abou...
December 11, 2024 at 17:21
I could generalise. If the PSR was not valid, one day, everything that had been beneficial to life could now be lethal to life, and vice versa. Could ...
December 11, 2024 at 15:12
Philosophically, how is it possible to know something about something we don't know about? In this particular case, that the something we don't know a...
December 11, 2024 at 15:04
The PSR states that for every fact there is a reason. If the PSR was not valid, and for every fact there was no reason, then there would be no reason ...
December 11, 2024 at 13:23
The expression "all events whether known or unknown" is a contradiction in terms. It is not possible to know that there are unknown events as they are...
December 11, 2024 at 11:24
Not everyone accepts the PSR, for example Hume. He challenged the PSR and argued that the ideas of cause and effect are distinct, and that we can conc...

PSR - for every fact there is an explanation Fact = light bends around sources with high mass Explanation = gravity There is no contradiction in the e...
December 11, 2024 at 10:48
On the one hand "light bends around sources with high mass due to gravity" and on the other hand "gravity causes light to bend around sources with hig...
December 11, 2024 at 10:06
In a sense it does, as light bends around sources with high mass due to gravity. From www.astronomy.com

The PSR states that for every event there is a reason The PSR is valid within certain restrictions. Prior to the light from the exploding star reachin...
December 10, 2024 at 17:54
True, there are different events. Let the PSR be that for each event there must be a reason Situation One - The rock falls, and I see it. There is eve...
December 10, 2024 at 12:56
Assume the PSR is not valid Then, if we observe a rock falling there would be no reason why we hadn't observed the rock not falling. But if we had obs...

Using Emilie du Chatelet's argument (SEP - PSR): P1 - The PSR in the OP states that for any thing that exists or is true, there is a sufficient reason...
December 09, 2024 at 16:52
True, but if a rock never fell to the ground when released, no one would ever have known about gravity. General relativity remains the framework for t...
December 09, 2024 at 16:15
1) Some people believe that for any thing that exists or is true, there is always a sufficient reason for it to exist or to be true. These people supp...
December 09, 2024 at 15:49
Suppose someone said that the reason a rock falls to the ground when released is because of gravity. Is "gravity" an explanation as to why the rock fa...
December 09, 2024 at 15:29
What are you saying?
December 09, 2024 at 14:23
The OP describes the PSR as "For any thing that exists or is true, there is a sufficient reason for it to exist or to be true." There are different de...
December 09, 2024 at 11:43
Yes, it would be unrealistic to assume that our limits are the measure of reality. As a cat may never understand the symbolism within The Old Man and ...
December 08, 2024 at 17:28
All those things are true: C1 - I could try to explain Hemingway's novel The old man and the sea to my pet cat until "the cows come home" without any ...
December 08, 2024 at 08:45
It could be that the phrase "at the same time" is crucial to the argument defending the Principle of Sufficient Reason. Parmenides pointed out that if...
December 07, 2024 at 17:42
I agree that by the Law of Contradiction, a fact/event cannot be other than it is at the same time. For a fact to be other than it is at the same time...

From the SEP article Principle of Sufficient Reason: the PSR may be formulated as "For every fact F, there must be a sufficient reason why F is the ca...
December 05, 2024 at 10:14
The Principle of Sufficient Reason (PSR) proposes that for every fact F, there must be a sufficient reason why F is the case (SEP - Principle of Suffi...

In addition, something that nobody understands cannot properly be used as a counter-argument against anything. As Feynman said "I think I can safely s...

It depends on the relationships between mind, perceiving, sensing, ideas and thoughts. For example, for Berkeley, what exactly is the relationship bet...

Kant writes that the term "principle" is ambiguous. Kant writes that on the one hand there are "principles absolutely" as used in the a priori concept...

The relation between thought (a priori) and being (synthetic) Paul Guyer and Allen Wood in the Introduction to CPR explicitly say that synthetic a pri...

Just taking your first point. Kant writes in CPR B14 section V that a synthetic a priori judgement is a principle of reason. The Merriam Webster Dicti...

Apart from my ongoing justification, based on the text, that "Kant's synthetic a priori is the principle that we can discover a priori necessity from ...

Kant starts his proof in CPR B276 with "I am conscious of my existence as determined in time", and continues with his proof that "The mere, but empiri...
November 02, 2024 at 13:11
In what way is Kant's proof in CPR B276 besides the point, ie "The mere, but empirically determined, consciousness of my own existence proves the exis...

In B276, Kant starts with the theorem: "The mere, but empirically determined, consciousness of my own existence proves the existence of objects in spa...

That's my question. Are scientific explanations literally true or metaphorically true? Is F = ma literal or metaphorical? According to Britannica arti...

It depends on the viewpoint. We can imagine a sense of scale in an early universe devoid of life from our viewpoint, but we can't imagine a sense of s...
