Full Idea
In many cases, the last three of the causes [aition] come to the same thing. What a thing is and its purpose are the same, and the original source of change is, in terms of form, the same as these two. After all, it is a man who generates a man.
Gist of Idea
A thing's form and purpose are often the same, and form can be the initiator of change too

A Reaction
One of the few illuminating remarks about what the 'form' in hylomorphism is supposed to do. This may be the key to virtue ethics - that the form of man, which we learn elsewhere is the psuché, is also man's drive and man's very purpose.
