I acknowledge that four thousand volumes of metaphysics will not teach us what our soul is.
VoltaireAll events are linked together in the best of possible worlds; after all, if you had not been driven from a fine castle by being kicked in the backside for love of Miss Cunegonde, if you hadn't been sent before the Inquisition, if you hadn't traveled across America on foot, if you hadn't given a good sword thrust to the baron, if you hadn't lost all your sheep from the good land of Eldorado, you wouldn't be sitting here eating candied citron and pistachios. - That is very well put, said Candide, but we must cultivate our garden.
VoltaireEverything happens through immutable laws, ...everything is necessary... There are, some persons say, some events which are necessary and others which are not. It would be very comic that one part of the world was arranged, and the other were not; that one part of what happens had to happen and that another part of what happens did not have to happen. If one looks closely at it, one sees that the doctrine contrary to that of destiny is absurd; but there are many people destined to reason badly; others not to reason at all others to persecute those who reason.
