Why, we valiantly and pugnaciously insist upon the verbal truth, that different natures ought to have different pursuits, but we never considered at all what was the meaning of sameness or difference of nature, or why we distinguished them when we assigned different pursuits to different natures and the same to the same natures.
because we never meant when we constructed the State, that the opposition of natures should extend to every difference, but only to those differences which affected the pursuit in which the individual is engaged; we should have argued, for example, that a physician and one who is in mind a physician may be said to have the same nature.
Again, to mark the nice distinction between two persons actuated by the same vice or folly is another; and, as this last talent is found in very few writers, so is the true discernment of it found in as few readers; though, I believe, the observation of this forms a very principal pleasure in those who are capable of the discovery; every person, for instance, can distinguish between Sir Epicure Mammon and Sir Fopling Flutter; but to note the difference between Sir Fopling Flutter and Sir Courtly Nice requires a more exquisite judgment: for want of which, vulgar spectators of plays very often do great injustice in the theatre; where I have sometimes known a poet in danger of being convicted as a thief, upon much worse evidence than the resemblance of hands hath been held to be in the law.
