A great doctor kills more people than a great general.

The present is saturated with the past and pregnant with the future.

Philosophy consists mostly of kicking up a lot of dust and then complaining that you can't see anything.

Of what use would it be to you, sir, to become King of China on condition that you forgot what you have been? Would it not be the same as if God, at the same time he destroyed you, created a King in China?

In whatever manner God created the world, it would always have been regular and in a certain general order. God, however, has chosen the most perfect, that is to say, the one which is at the same time the simplest in hypothesis and the richest in phenomena.

It's easier to be original and foolish than original and wise.

What is is what must be.
