It is all our life is worth to know if the soul be mortal or immortal.

Fascinatio nugacitatis.—In order that passion may do no hurt, we should act as though we had but a week to live.

If we ought to give a week we ought to give our whole life.

In short, what is it you promise me if not ten years of self-love spent in trying hard to please without success, besides the troubles which are certain? For ten years is the probability.

Let us imagine a number of men in chains, all condemned to death, of whom some are strangled every day in the sight of the others, while those who remain see their own condition in that of their fellows, and wait their turn looking at each other sorrowfully and without hope. This is an image of the lot of man.

We must know ourselves, and if that does not serve to discover truth, it at least serves to regulate our lives, and there is nothing more just.

There are but three classes of persons: those who having found God, serve him; those who not having found him, diligently seek him; those who not having found him, live without seeking him. The first are happy and wise, the last are unhappy and fools, those between are unhappy, but they are wise.

The ordinary world has the power of not thinking about what it does not choose to think about. "Do not reflect on those passages about the Messiah," said the Jew to his son. So our people often act. Thus false religions are preserved, and the true also, as regards many people.
