However, for the man who studies to gain insight, books and studies are merely rungs of the ladder on which he climbs to the summit of knowledge. As soon as a rung has raised him up one step, he leaves it behind. On the other hand, the many who study in order to fill their memory do not use the rungs of the ladder for climbing, but take them off and load themselves with them to take away, rejoicing at the increasing weight of the burden. They remain below forever, because they bear what should have bourne them.
Still, instead of trusting what their own minds tell them, men have as a rule a weakness for trusting others who pretend to supernatural sources of knowledge.
Whoever wants his judgment to be believed, should express it coolly and dispassionately; for all vehemence springs from the will. And so the judgment might be attributed to the will and not to knowledge, which by its nature is cold.

If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much — and then performed so little.
Nothing in life gives a man so much courage as the attainment or renewal of the conviction that other people regard him with favor; because it means that everyone joins to give him help and protection, which is an infinitely stronger bulwark against the ills of life than anything he can do himself.
