All your trouble comes from lack of exercise. A man of your strength and constitution ought always to have kept physically active. So don't jibe at the very wise advice that sentences you to one hour's walk a day. You imagine the work of the mind takes place only in the brain; but you're much mistaken. It takes place in the legs as well.

Young love needs dangers and barriers to nourish it.

When I tried to draw near, you dissolved into air before my lips could touch you...

Unrequited love is as different from the mutual love as the error from the truth.

Try to keep your soul young and quivering right up to old age.

I saw in 'the wandering Jew' the personification of the Jewish people, exiled in the Middle Ages. Nevertheless, they are once again extremely rich, owing to their unfailing rude greediness and their indefatigable activity. With their hard-heartedness that they extend toward people of other faiths and races they are at the point of making themselves kings of the world. This people can thank its obstinacy that France will be Judized within fifty years. Already some wise Jews prophesy this frankly.

The life of great geniuses is nothing but a sublime storm.
