Everything of importance has been said before by somebody who did not discover it.
Alfred North WhiteheadThere is only one subject matter for education, and that is Life in all its manifestations
Alfred North WhiteheadThe vitality of thought is in adventure. Idea's won't keep. Something must be done about them. When the idea is new, its custodians have fervour, live for it, and, if need be, die for it. Their inheritors receive the idea, perhaps now strong and successful, but without inheriting the fervour; so the idea settles down to a comfortable middle age, turns senile, and dies.
