Men don't achieve truth because they lack humility and love of truth. They won't criticize their own beliefs. Truth would overwhelm them.

The soul may be immortal because she is fitted to rise towards that which is neither born nor dies, towards that which exists substantially, necessarily, invariably, that is to say towards God.

Man is saved by love and duty, and by the hope that springs from duty, or rather from the moral facts of consciousness, as a flower springs from the soil.

The more a man loves, the more he suffers. The sum of possible grief for each soul is in proportion to its degree of perfection.

It is by teaching that we teach ourselves, by relating that we observe, by affirming that we examine, by showing that we look, by writing that we think, by pumping that we draw water into the well.

The only substance properly so called is the soul.

Man becomes man only by his intelligence, but he is man only by his heart.
