 we may conclude that they who would acquire a knowledge of Statesmanship must have in addition practice.

But of the Sophists they who profess to teach it are plainly a long way off from doing so: in fact, they have no knowledge at all of its nature and objects; if they had, they would never have put it on the same footing with Rhetoric or even on a lower: neither would they have conceived it to be "an easy matter to legislate by simply collecting such laws as are famous because of course one could select the best," as though the selection were not a matter of skill, and the judging aright a very great matter, as in Music: for they alone, who have practical knowledge of a thing, can judge the performances rightly or understand with what means and in what way they are accomplished, and what harmonises with what: the unlearned must be content with being able to discover whether the result is good or bad, as in painting.

Now laws may be called the performances or tangible results of Political Science; how then can a man acquire from these the faculty of Legislation, or choose the best? we do not see men made physicians by compilations: and yet in these treatises men endeavour to give not only the cases but also how they may be cured, and the proper treatment in each case, dividing the various bodily habits. Well, these are thought to be useful to professional men, but to the unprofessional useless.
