We have no words for speaking of wisdom to the stupid. He who understands the wise is wise already.
Georg C. LichtenbergA good method of discovery is to imagine certain members of a system removed and then see how what is left would behave: for example, where would we be if iron were absent from the world: this is an old example.
Georg C. LichtenbergJust as we outgrow a pair of trousers, we outgrow acquaintances, libraries, principles, etc., at times before they're worn out and times - and this is the worst of all - before we have new ones.
