By "essence" I understand a universal, of any degree of complexity and definition, which may be given immediately, whether to sense or to thought.... This object of pure sense or pure thought, with no belief superadded, an object inwardly complete and individual, but without external relations or physical status, is what I call an essence.
George SantayanaFriendship is almost always the union of a part of one mind with the part of another; people are friends in spots.
