Phronimos, possessing practical wisdom . But the only virtue special to a ruler is practical wisdom; all the others must be possessed, so it seems, both by rulers and ruled. The virtue of a person being ruled is not practical wisdom but correct opinion; he is rather like a person who makes the pipes, while the ruler is the one who can play them.
AristotleThat which is impossible and probable is better than that which is possible and improbable.
Aristotle...we are all inclined to ... direct our inquiry not by the matter itself, but by the views of our opponents; and, even when interrogating oneself, one pushes the inquiry only to the point at which one can no longer offer any opposition. Hence a good inquirer will be one who is ready in bringing forward the objections proper to the genus, and that he will be when he has gained an understanding of the differences.
Aristotle
