“Where did I get it from? Was it by reason that I attained to the knowledge that I must love my neighbour and not throttle him? They told me so when I was a child, and I gladly believed it, because they told me what was already in my soul. But who discovered it? Not reason! Reason has discovered the struggle for existence and the law that I must throttle all those who hinder the satisfaction of my desires. That is the deduction reason makes. But the law of loving others could not be discovered by reason, because it is unreasonable.”

“These prin­ciples laid down as in variable rules: that one must pay a card sharper, but need not pay a tailor; that one must never tell a lie to a man, but one may to a woman; that one must never cheat any one, but one may a husband; that one must never pardon an insult, but one may give one and so on. These principles were possibly not reasonable and not good, but they were of unfailing certainty, and so long as he adhered to them, Vronsky felt that his heart was at peace and he could hold his head up.”

“Was it through reason that I arrived at the necessity of loving my neighbor and not throttling him?...Not reason. Reason discovered the struggle for existence and the law which demands that everyone who hinders the satisfaction of my desires should be throttled. That is the conclusion of reason. Reason could not discover love for the other, because it’s unreasonable.”

“If there is a God and future life, there is truth and good, and man's highest happiness consists in striving to attain them. We must live, we must love, and we must believe that we live not only today on this scrap of earth, but have lived and shall live”

“In order to understand, observe, deduce, man must first be conscious of himself as alive.”

“Drama, instead of telling us the whole of a man's life, must place him in such a situation, tie such a knot, that when it is untied, the whole man is visible.”
