He who learns must suffer. And even in our sleep pain that cannot forget falls drop by drop upon the heart, and in our own despair, against our will, comes wisdom to us by the awful grace of God.

Alas for the affairs of men! When they are fortunate you might compare them to a shadow; and if they are unfortunate, a wet sponge with one dash wipes the picture away.

As long as there are men the bulwark is safe.

Those who would learn must suffer. In our own despair, against our will, wisdom comes to us.

There is no pain so great as the memory of joy in present grief.

It is in the character of very few men to honor without envy a friend who has prospered.

Learning is ever in the freshness of its youth, even for the old.
