Book 2
8
Whereas clearly it is specially an End that a man wishes, and the feeling that he ought to be healthy and prosperous is an opinion. So these considerations make it clear that purposive choice is different from both opinion and wish. Forming wishes and forming opinions apply specially to one’s End; purposive choice is not of Ends.
9
It is clear, then, that purposive choice is not either wish or opinion or judgement simply; but in what does it differ from them? and how is it related to the voluntary?To answer these questions will make it clear what purposive choice is.
10
Now of things that can both be and not be, some are such that it is possible to deliberate about them, but about others it is not possible. Some things can either be or not be but their coming into being does not rest with us, but in some cases is due to the operation of nature and in others to other causes; and about these things nobody would deliberate unless in ignorance of the facts.
11
But with some things not only their existence or non-existence is possible, but also for human beings to deliberate about them; and these are all the things that it rests with us to do or not to do. Hence we do not deliberate about affairs in India, or about how to square the circle; for affairs in India do not rest with us, whereas the objects of choice and things practicable are among things resting with us, and squaring the circle is entirely impracticable (and thus it is clear that purposive choice is not simply opinion either).
