Behold a universe so immense that I am lost in it. I no longer know where I am. I am just nothing at all. Our world is terrifying in its insignificance.

I have lived one hundred years; and I die with the consolation of never having thrown the slightest ridicule upon the smallest virtue.

It is high time for me to depart, for at my age I now begin to see things as they really are.

It is the passions that do and undo everything.

A well-cultivated mind is, so to speak, made up of all the minds of preceding ages; it is only one single mind which has been educated during all this time.

A philospher sees the Earth as a large planet, travelling through the heavens, covered with fools

An educated mind is, as it were, composed of all the minds of preceding ages.
