Kitap 2

But purposive choice does not deal with all the practicable things resting with us either.
13
Hence one might also raise the question, why is it exactly that, whereas doctors deliberate about things in their field of science, scholars do not? The reason is that since error occurs in two ways (for we err either in reasoning, or in perception when actually doing the thing), in medicine it is possible to err in both ways, but in grammar error only occurs in our perception and action, to investigate which would be an endless undertaking.
14
Since then purposive choice is not either opinion nor wish separately, nor yet both (for no one makes a deliberate choice suddenly, but men do suddenly think they ought to act and wish to act), therefore it arises as from both, for both of them are present with a person choosing.
15
But how purposive choice arises out of opinion and wish must be considered. And indeed in a manner the actual term choice makes this clear. Choice is taking, but not taking simply—it is taking one thing in preference to another; but this cannot be done without consideration and deliberation; hence purposive choice arises out of deliberative opinion.
