It quite often happens that the old man is subject to the delusion of a great moral renewal and rebirth, and from this experience he passes judgments on the work and course of his life, as if he had only now become clear-sighted; and yet the inspiration behind this feeling of well-being and these confident judgements is not wisdom, but weariness .

Beware of spitting against the wind!

Untroubled, scornful, outrageous - that is how wisdom wants us to be: she is a woman and never loves anyone but a warrior.

The love of power is the demon of mankind.

No one dies of fatal truths nowadays: there are too many antidotes.

It is not doubt,is certitude that drives you mad.

Concerning great things one should either be silent or speak loftily.
