Full Idea
As we see that eye, hand and foot have some function, should we not assume a human being has a function over and above these?
Clarification
'Function' is the Greek word 'ergon'
Gist of Idea
If bodily organs have functions, presumably the whole person has one
Source
Aristotle (Nicomachean Ethics [c.334 BCE], 1097b30)
Book Reference

A Reaction
This seems to be a case of the fallacy of composition - you can't infer the function of the whole from the function of the parts. This error by the great man smacks of desperation, but it leaves untouched his general claim that man has a function.
