Abstract
Matter is accepted as something unknown in itself, but that does not mean you cannot talk about it. Aristotle believed you can give the description of matter by using analogies. We first come up with the term ‘matter’ in Physics I.7. Aristotle uses it in relation with the problems of change and movement; then in metaphysics it is used in connection with form. Matter and form are accepted as the aspects of the one and same being, in a different level of being though. Because matter is usually associated with potentiality and form is with activity. Therefore, our main problem in this paper is how to make a definition of something and regarding what, that is, to matter or form? Aristotle’s answer for that question will be form because he thought that form is always prior to, and a more real being than matter. We have lots of potentialities throughout our lives, but only some of them are actualized. Thus, if someone wants to make a definition of us, he has to make it in virtue of considering our form.
