"Speech is human nature itself, with none of the artificiality of written language." ― Alfred North Whitehead Topic(s): Nature More From Alfred North Whitehead "Not ignorance, but ignorance of ignorance, is the death of knowledge." "Philosophy begins in wonder. And, at the end, when philosophic thought has done its best, the wonder remains." "Knowledge shrinks as wisdom grows." More In Nature "Teach a child to play solitaire, and she’ll be able to entertain herself when there’s no one around. Teach her tennis, and she’ll know what to do when she’s on a court. But raise her to feel comfortable in nature, and the whole planet is her home."― Joyce Maynard "Human Nature is the only science of man; and yet has been hitherto the most neglected."― David Hume "Nature has no principles. She makes no distinction between good and evil."― Anatole France
