 The coldness and hardness, which a Man feels in a piece of Ice, being as distinct Ideas in the Mind, as the Smell and Whiteness of a Lily; or as the taste of Sugar, and smell of a Rose: And there is nothing can be plainer to a Man, than the clear and distinct Perception he has of those simple Ideas; which being each in it self uncompounded, contains in it nothing but one uniform Appearance, or Conception in the mind, and is not distinguishable into different Ideas. (II.ii.1)
