and ascertain all their capacities: for we have already stated that these are the object-matter of sciences.
If then it appears that we may become good through the instrumentality of laws, of course whoso wishes to make men better by a system of care and training must try to make a Legislator of himself; for to treat skilfully just any one who may be put before you is not what any ordinary person can do, but, if any one, he who has knowledge; as in the healing art, and all others which involve careful practice and skill.
Will not then our next business be to inquire from what sources, or how one may acquire this faculty of Legislation; or shall we say, that, as in similar cases, Statesmen are the people to learn from, since this faculty was thought to be a part of the Social Science? Must we not admit that the Political Science plainly does not stand on a similar footing to that of other sciences and faculties? I mean, that while in all other cases those who impart the faculties and themselves exert them are identical (physicians and painters for instance) matters of Statesmanship the Sophists profess to teach,1181a but not one of them practises it, that being left to those actually engaged in it: and these might really very well be thought to do it by some singular knack and by mere practice rather than by any intellectual process: for they neither write nor speak on these matters (though it might be more to their credit than composing speeches for the courts or the assembly), nor again have they made Statesmen of their own sons or their friends.
One can hardly suppose but that they would have done so if they could, seeing that they could have bequeathed no more precious legacy to their communities, nor would they have preferred, for themselves or their dearest friends, the possession of any faculty rather than this.
Practice, however, seems to contribute no little to its acquisition; merely breathing the atmosphere of politics would never have made Statesmen of them, and therefore
