Everything 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.
It would be very singular that all nature, all the planets, should obey eternal laws, and that there should be a little animal five feet high, who, in contempt of these laws, could act as he pleased, solely according to his caprice.
