The novel of Candide is full of many philosophical ideas. One of the main ideas of the story is that everything is for the best, there is no effect without an effect. pg.20.
Translated By John Butt "That things cannot be other than they are, for since everything was made for a purpose, it follows that everything is made for the best purpose. It follows that those who maintain that all is right talk nonsense; they ought to say that all is for the best."
