While it is generally accepted that we need to use our intelligence in order to get what we want, it is thought to be a cardinal error to imagine that by reasoning we can discover what we ought to want. Reason can in no way constrain the choice of ends, it can only constrain the choice of means once an end has been adopted. In Plato's philosophy we find a view strongly opposed to this attitude towards reason. It is widely (...) held, however, that to arrive at a position which is plainly opposed to common sense, Plato must have grossly confused reasoning about means with reasoning about ends. Evidence of this confusion is found in Plato's use of analogies between statecraft and navigation, and between virtue and skill. But the diagnosis of confusion rests on a misunderstanding of how Plato wanted to use the word translated ‘skill’, i.e. ‘ technē ’, and this misunderstanding is shared even by those who see Plato as rejecting the virtue/skill analogy.
