ething which underlies that which is in the process of becoming and that this, even if numerically one, in kind at least is not one” (Physics I, 7, 109a10-17). When a man becomes musical, he “persists during the generation and is still a man, but the not-musical or the unmusical does not persist” (Physics I, 7 190a12). Therefore, there are two types of becoming or change, the accidental, in which it exists only of substance, and the substantial, in which there is an underlying matter. An example of a change without qualification is that which is generated by a shape change as in a statue from unformed bronze. However, everything which is generated is generated form a subject and a form. The musical man is composed of a man and the musical. Therefore, change consists of three principles. Parmenides was wrong in his denial of becoming because he assumed that, “no thing can be generated or be destroyed because a thing must be generated either from being or from nonbeing; but both of these are impossible, for being cannot become something since it already exists, and a thing generated cannot come to be from nonbeing since there must be some underlying subject” (Physics I,8, ln 25-31). Since he also assumed no plurality of things and being only exists as itself, he was wrong in his conclusion. Parmenides fails to make the distinction that in expressing as being generated form being or from nonbeing, the expressions have two senses. “Generation from being in a qualified sense exists with respect to an attribute” (Physics I, 8, ln 14). Being is generated from nonbeing through privation. Generation from being is also through privation since the generation only exists in respect to an attribute. In addition to Parmenides, Plato also fails to distinguish between the two different senses of nonbeing. Plato has distinguished that there is a need for an underlying nature but posits the triad ...
