Why should not every individual man have existed more than once upon this world? Why should I not come back as often as I am capable of acquiring fresh knowledge? Is this hypothesis so laughable merely because it is the oldest? Because the human understanding, before the sophistries of the schools had dissipated and debilitated it, lighted upon it at once?

A man who does not lose his reason over certain things has none to lose.

The search for truth is more precious than its possession.

What can the Creator see with greater pleasure than a happy creature?

Yesterday I lived, today I suffer, tomorrow I die; but I still think fondly, today and tomorrow, of yesterday.

If some things don't make you lose your sense of reason, then you have none to lose.

Resist as much as thou wilt; heaven's ways are heaven's ways.
