Miracles are not contrary to nature, but only contrary to what we know about nature.

Love can be angry... with a kind of anger in which there is no gall, like the dove's and not the ravens.

We cannot pass our guardian angel's bounds, resigned or sullen, he will hear our sighs.

The one who is good, is free even being a slave; the one who is bad remains a slave even being a king.

The most venerable, clearly understood, enlightened, and reliable constant in the world is not only that we want to be happy, but that we want only to be so. Our very nature requires it of us.

Indeed, man wishes to be happy even when he so lives as to make happiness impossible.

Keep on adding, keep on walking, keep on progressing: do not delay on the road, do not go back, do not deviate.
