Our character is composed of our ideas and our feelings: and, since it has been proved that we give ourselves neither feelings nor ideas, our character does not depend on us. If it did depend on us, there is nobody who would not be perfect. If one does not reflect, one thinks oneself master of everything; but when one does reflect, one realizes that one is master of nothing
VoltaireIt is with books as with the fires of our grates, everybody borrows a light from his neighbor to kindle his own, which in turn is communicated to others, and each partakes of all.
Voltaire
