Several times I asked myself, "Can it be that I have overlooked something, that there is something which I have failed to understand? Is it not possible that this state of despair is common to everyone?" And I searched for an answer to my questions in every area of knowledge acquired by man.

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.
