Wise as serpents

From Francis Bacon’s De Augmentis Scientiarum , 7.1: “For as the fable goes of the basilisk, that if he sees you first, you die for it, but if you see him first, he dies; so itis with deceits, impostures, and evil arts, which, if they be first espied, they lose their life, but if they prevent [come first] they endanger; so that we are much beholden to Machiavelli and other writers of that class, who openly and unfeignedly declare or describe what men do, and not what they ought to do. For it is not possible to join the wisdom of the serpent with the innocence of the dove, except men be perfectly acquainted with the nature of evil itself; for without this, virtue is open and unfenced; nay, a virtuous and honest man can do no good upon those that are wicked, to correct and reclaim them, without first exploring all the depths and recesses of their malice.”
