Nature has given us the seeds of knowledge, not knowledge itself.

The way to wickedness is always through wickedness.

To be always fortunate, and to pass through life with a soul that has never known sorrow, is to be ignorant of one half of nature.

The greatest loss of time is delay and expectation, which depend upon the future. We let go the present, which we have in our power, and look forward to that which depends upon chance, and so relinquish a certainty for an uncertainty.

The largest part of goodness is the will to become good.

Those griefs burn most which gall in secret.

A dwarf is small even if he stands on a mountain; a colossus keeps his height, even if he stands in a well.
