John LockeDefects and weakness in men's understandings, as well as other faculties, come from want of a right use of their own minds; I am apt to think, the fault is generally mislaid upon nature, and there is often a complaint of want of parts, when the fault lies in want of a due improvement of them.
John LockeHe that in the ordinary affairs of life would admit of nothing but direct plain demonstration would be sure of nothing in this world but of perishing quickly.
