So it is plain that Science must mean the most accurate of all Knowledge; but if so, then the Scientific man must not merely know the deductions from the First Principles but be in possession of truth respecting the First Principles. So that Science must be equivalent to Intuition and Knowledge; it is, so to speak, Knowledge of the most precious objects, _with a head on_.[23] I say of the most precious things, because it is absurd to suppose πολιτικὴ,[24] or Practical Wisdom, to be the highest, unless it can be shown that Man is the most excellent of all that exists in the Universe. Now if “healthy” and “good” are relative terms, differing when applied to men or to fish, but “white” and “straight” are the same always, men must allow that the Scientific is the same always, but the Practically Wise varies: for whatever provides all things well for itself, to this they would apply the term Practically Wise, and commit these matters to it; which is the reason, by the way, that they call some brutes Practically Wise, such that is as plainly have a faculty of forethought respecting their own subsistence. And it is quite plain that Science and πολιτικὴ cannot be identical: because if men give the name of Science to that faculty which is employed upon what is expedient for themselves, there will be many instead of one, because there is not one and the same faculty employed on the good of all animals collectively, unless in the same sense as you may say there is one art of healing with respect to all living beings. If it is urged that man is superior to all other animals, that makes no difference: for there are many other things more Godlike in their nature than Man, as, most obviously, the elements of which the Universe is composed.[25] It is plain then that Science is the union of Knowledge and Intuition, and has for its objects those things which are most precious in their nature. Accordingly, Anexagoras, Thales, and men of that stamp, people call Scientific, but not Practically Wise because they see them ignorant of what concerns themselves; and they say that what they know is quite out of the common run certainly, and wonderful, and hard, and very fine no doubt, but still useless because they do not seek after what is good for them as men. Chapter VIII. But Practical Wisdom is employed upon human matters, and such as are objects of deliberation (for we say, that to deliberate well is most peculiarly the work of the man who possesses this Wisdom), and no man deliberates about things which cannot be otherwise than they are, nor about any save those that have some definite End and this End good resulting from Moral Action; and the man to whom we should give the name of Good in Counsel, simply and without modification, is he who in the way of calculation has a capacity for attaining that of practical goods which is the best for Man.
