A mind that questions everything, unless strong enough to bear the weight of its ignorance, risks questioning itself and being engulfed in doubt. If it cannot discover the claims to existence of the objects of its questioning -- and it would be miraculous if it so soon succeeded in solving so many mysteries -- it will deny them all reality, the mere formulation of the problem already implying an inclination to negative solutions. But in so doing it will become void of all positive content and, finding nothing which offers it resistance, will launch itself perforce into the emptiness of inner revere.
Man could not live if he were entirely impervious to sadness. Many sorrows can be endured only by being embraced, and the pleasure taken in them naturally has a somewhat melancholy character. So, melancholy is morbid only when it occupies too much place in life; but it is equally morbid for it to be wholly excluded from life.
One cannot long remain so absorbed in contemplation of emptiness without being increasingly attracted to it. In vain one bestows on it the name of infinity; this does not change its nature. When one feels such pleasure in non-existence, one's inclination can be completely satisfied only by completely ceasing to exist.
Man's characteristic privilege is that the bond he accepts is not physical but moral; that is, social. He is governed not by a material environment brutally imposed on him, but by a conscience superior to his own, the superiority of which he feels. Because the greater, better part of his existence transcends the body, he escapes the body's yoke, but is subject to that of society.
The man whose whole activity is diverted to inner meditation becomes insensible to all his surroundings. If he loves, it is not to give himself, to blend in fecund union with another being, but to meditate on his love. His passions are mere appearances, being sterile. They are dissipated in futile imaginings, producing nothing external to themselves.
There is no society known where a more or less developed criminality is not found under different forms. No people exists whose morality is not daily infringed upon. We must therefore call crime necessary and declare that it cannot be non-existent, that the fundamental conditions of social organization, as they are understood, logically imply it.
