Mostly the loss teaches us only about the value of things.

Just as one spoils the stomach by overfeeding and thereby impairs the whole body, so can one overload and choke the mind by giving it too much nourishment. For the more one reads the fewer are the traces left of what one has read; the mind is like a tablet that has been written over and over. Hence it is impossible to reflect; and it is only by reflection that one can assimilate what one has read. If one reads straight ahead without pondering over it later, what has been read does not take root, but is for the most part lost.

He who does not enjoy solitude will not love freedom.

We may divide thinkers into those who think for themselves and those who think through others. The latter are the rule and the former the exception. The first are original thinkers in a double sense, and egotists in the noblest meaning of the word.

A happy life is impos­si­ble; the best that a man can attain is a heroic life.

A word too much always defeats its purpose.

And yet, just as our body would burst asunder if the pressure of the atmosphere were removed from it, so would the arrogance of men expand, if not to the point of bursting then to that of the most unbridled folly, indeed madness, if the pressure of want, toil, calamity and frustration were removed from their life. One can even say that we require at all times a certain quantity of care or sorrow or want, as a ship requires ballast, in order to keep on a straight course.
