Decisive inventions and discoveries always are initiated by an intellectual or moral stimulus as their actual motivating force, but, usually, the final impetus to human action is given by material impulses ... merchants stood as a driving force behind the heroes of the age of discovery; this first heroic impulse to conquer the world emanated from very mortal forces

One never gets to know a person's character better than by watching his behavior during decisive moments.... It is always only danger which forces the most deeply hidden strengths and abilities of a human being to come forth.

He was, like everyone of a strongly erotic disposition, twice as good, twice as much himself when he knew that women liked him, just as many actors find their most ardent vein when they sense that they have cast their spell over the audience, the breathing mass of spectators before them.

It remains an irrefragable law of history that contemporaries are denied a recognition of the early beginnings of the great movements which determine their times.

There are two kinds of pity. One, the weak and sentimental kind, which is really no more than the heart's impatience to be rid as quickly as possible of the painful emotion aroused by the sight of another's unhappiness, that pity which is not compassion, but only an instinctive desire to fortify one's own soul agains the sufferings of another; and the other, the only one at counts, the unsentimental but creative kind, which knows what it is about and is determined to hold out, in patience and forbearance, to the very limit of its strength and even beyond.

Hearing, seeing and understanding each other, humanity from one end of the earth to the other now lives simultaneously, omnipresent like a god thanks to its own creative ability. And, thanks to its victory over space and time, it would now be splendidly united for all time, if it were not confused again and again by that fatal delusion which causes humankind to keep on destroying this grandiose unity and to destroy itself with the same resources which gave it power over the elements.

Human life is so strangely constituted that even perfected intellectual understanding combined with the richest experience is incapable of conquering innate weaknesses. Even if it thoroughly analyzes itself, psychology (and this is one of the dubious aspects of psychoanalysis) can, to be sure, recognize its flawed native characteristics, but it cannot eliminate them. Understanding (them) is not the same as overcoming (them) and, again and again, we see the wisest of human beings helpless in the fact of their small follies which everyone else observes with a smile.
