Aristotle on Change It is characteristic of substances according to the Categories to undergo change. And "natural things are some or all of them subject to change" Phys.
First, as you may know, Parmenides survives only through a very few ancient fragments, ancient references, and Plato's narrative. Yet strangely, much of modern physics remains "Parmenidean" in its treatment of spacetime and the mathematical "framing" of motion or change.
Parmenides asks where "change" or "the new" comes from. Presumably nothing can come out of "nothing," ex nihilo. How can something be contained in or deduced from Similarly, if there exists some "thing," how can some "other thing" come out of it? You are, I believe, correct to assume that Parmenides means by "being" roughly existence or "is-ness.
Where something "new" comes from seems completely unproblematic to most of us. But if you accept basic rules of noncontradiction or the excluded middle, etc. Things "exist" or "don't exist. It is well worth reading the opening of Hegel's "Science of Logic" to ponder this problem.
And "ponder" is the right word. You don't just "work it out" logically. The problem then is explaining or defining flux, transformation, or "motion" of any sort. This is hardly as arcane or as settled a matter as some think. It is the whole career of modern science since Galileo.
It impinges on calculus and physics and measurement problems at many, many levels. And it is difficult because it is way, way too basic. We introduce "becoming" or "possibility" or "could" or "dialectic" or "Trinity" or some other acceptable covering term for the officially "excluded middle.
When you say you have difficulty grasping this, welcome to the club.
Parmenides remains in our texts because he raised a question so fundamental it still perplexes modern physics, while also generating endless answers.Mar 09, · Thus far, Aristotle’s philosophy of nature is understood from his analysis of change and when he undertook to explain how change occurs in things, he had first to confront the logic of Parmenides; who posited that there is, in reality no change at all.
All change is mere appearance; reality is One and this One, which only is, is unchanging. Aristotle on Change The Physics The Physics is a study of nature (ta phusika), as opposed to the Metaphysics (ta meta ta phusika —lit., “the stuff that comes after the stuff on nature”) which studies beings in general, not just natural objects.
At the end of Zeno's performance, Pythodorus, Parmenides, and Aristotle, who have been waiting outside the house, return and witness an exchange between Zeno and Socrates. The exchange begins with Socrates' summary . Aristotle on Change. It is characteristic of substances (according to the Categories) to undergo benjaminpohle.com "natural things are some or all of them subject to change" (Phys.I.
2, a). We know this was a topic that puzzled Aristotle's predecessors. Sep 01, · Aristotle, simply rejected this argument on the grounds that we can observe things in motion, but this isn't very effective because Parmenides already argument that motion is an illusion.
The difficuly in this paradox is that of the infinite, which Greek mathematics couldn't handle, and it would require a far more sophisticated relationship with infinity in mathematics for this problem ultimately to Author: The Skeptical Philosopher.
Aristotle gives an analysis of change that enables him to avoid this dilemma. His account is designed to explain both how change in general is possible, and how coming into existence is possible.
