All intelligent thoughts have already been thought; what is necessary is only to try to think them again.

When things are bad, we take comfort in the thought that they could always be worse. And when they are, we find hope in the thought that things are so bad they have to get better.

All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, till they take root in our personal experience.

Thought expands, but paralyzes; action animates, but narrows.

Mediocrity has no greater consolation than in the thought that genius is not immortal

Yes! To this thought I hold with firm persistence; The last result of wisdom stamps it true; He only earns his freedom and existence Who daily conquers them anew.
