"Unhappiness makes people vulnerable, incessant suffering unjust. Just as in the relations between a creditor and a debtor there is always an element of the disagreeable that can never be overcome, for the very reason that the one is irrevocably committed to the role of giver and the other to that of receiver, so in a sick person a latent feeling of resentment at every obvious sign of consideration is always ready to burst forth."

“The heart is able to bury deep and well what is urgently desires to forget.”

“Nothing moves young people so much as to witness a sublime and virile gloom. Michelangelo's thinker staring down into the abyss of his own thoughts, Beethoven's poignantly drawn lips; these tragical masks of universal suffering touch the crude emotions of youth far more than Mozart's silver melodies or the crystalline light that radiates from Leonardo's figures. Being itself beauty, youth has no need of transfiguration. In the superabundance of its vital forces, it is allured by the tragical, and in its inexperience, is prone to accept the embraces of melancholy. That, too, is why youth is always ready for danger, and ever willing to extend a brotherly hand towards mental pain.”

“The soul is made of stuff so mysteriously elastic that a single event can make it big enough to contain the infinite.”

“Everywhere soldiering entails the same busily empty monotony; hour after hour is mapped out in accordance with inflexible, antediluvian regulations, and even one's leisure does not seem to offer much in the way of variety. In the officers' mess the same faces, the same conversation; at the cafe the same games of cards and billiards.”

“Gratitude is a rare frame of mind; and those who are grateful can seldom find a way to express what they feel. They are overwhelmed by silence; are shamefaced; and, sometimes, actually try to hide their feelings.”

“When one does another person an injustice, in some mysterious way it does one good to discover that the injured party has also behaved badly or unfairly in some little matter or other; it is always a relief to the conscience if one can apportion some measure of guilt to the person one has betrayed.”
