There is no such thing as an accident. What we call by that name is the effect of some cause which we do not see.
VoltaireWe are going to a new world... and no doubt it is there that everything is for the best; for it must be admitted that one might lament a little over the physical and moral happenings of our own world.
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.
Voltaire
