Aristotle discovered new ideas through experimentation. Motivated like any other living creature, moving about on hands and knees, baby Ari sought to improve his lot in life by solving puzzles and increasing his awareness. As he moved about, bumping into this and that one can easily imagine his mother giving him a word now and then as labels for his successes.
There and are no completed works of this man; he began life and ended it the same way; by seeking safety. During the last year of his life, Aristotle fled what he perceived to bea dangerous new government and spent the last year of his life living with his mother in her home. About the only thing known about this time in his life is that he died of a belly ache.
