Question

Which one of Plato's idea did Aristotle disagree with?

Answer 1

Aristotle disagreed with Plato about several things, but what you're probably looking for is Plato's great obsession, usually referred to as the Theory of Forms.  This is a theory that all objects on Earth, such as trees, rocks, houses, etc, are reflections of some Idealized Form or Idea of Tree, Rock, and House, which exist in some other reality,  This also applied to abstractions such as truth or justice.  

Cister is wrong in saying that Aristotle believed this.  It was Plato's idea which Aristotle rejected with the famous statement, "Plato is dear but truth is dearer."

Answer 2

that his p***s was bigger than Aristotle's....

...i don't really pay attention in world civ.

Answer 3

Yes the two people above pretty much said it all. Plato believed in the ideal form of everything. He thought that there was another more ideal world which is the perfect blueprint of the world we live in. Plato thought that that world was flawless. Aristotle was more solid in what he believed in (probobly because he was a man of science and not a poet).

Answer 4

Over the existence of ideal forms.

Aristotle believed that forms or ideas, such as truth or good, exist in a realm beyond the material world which is Aristotle's most widely known theory.
