For it is not possible to join serpentine wisdom with columbine innocence, except men know exactly all the conditions of the serpent: his baseness and going upon his belly, his volubility and lubricity, his envy and sting, and the rest; that is, all forms and natures of evil: for without this, virtue lieth open and unfenced.
Francis BaconThe inquiry of truth, which is the love-making, or the wooing of it, the knowledge of truth, which is the presence of it, and the belief of truth, which is the enjoying of it, is the sovereign good of human nature.
Francis Bacon
