The passions are the winds which fill the sails of the vessel; they sink it at times, but without them it would be impossible to make way.
VoltaireOur 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
