In Metaphysics, Book 1 chapter 4, Aristotle uses Plato’s view of numbers and how he compares them to his view of perceptible things and form, to argue that Plato and the Platonists are wrong in their ideas relating to Form. On page 234 he clarifies that Plato states numbers as being everlasting and immobile, in contrast to perceptible things, and differentiates numbers to forms by saying there are many of the same kind. Aristotle, however, claims that the agents that apply to form, can create many forms, contrary to Plato’s beliefs.

Aristotle’s explanation to Plato’s mistakes is that Plato only considers two of the four causes. He claims that Plato only uses material cause and the efficient cause, however he does not consider the the Form or the final cause (the end product). Because he fails to consider all aspects of numbers and perceptible things, Plato fails to see all possible aspects and possibility of form.

This passage caught my attention because it redefined the idea of form.  Aristotle clarifies the idea that form is not individual to a specific material, but that the same form can exist in infinite amount of things, such as numbers.  He uses the example of a table, and explains that more than one table can be made into the same form because it the the agent that applies the form that is important rather than the material.
