“Though men in their hundreds of thousands had tried their hardest to disfigure that little corner of the earth where they had crowded themselves together, paving the ground with stones so that nothing could grow, weeding out every blade of vegetation, filling the air with the fumes of coal and gas, cutting down trees and driving away every beast and every bird -- spring, however, was still spring, even in the town. The sun shone warm, the grass, wherever it had not been scraped away, revived and showed green not only on the narrow strips of lawn on the boulevards but between the paving-stones as well, and the birches, the poplars and the wild cherry-trees were unfolding their sticky, fragrant leaves, and the swelling buds were bursting on the lime trees; the jackdaws, the sparrows and the pigeons were cheerfully getting their nests ready for the spring, and the flies, warmed by the sunshine, buzzed gaily along the walls. All were happy -- plants, birds, insects and children. But grown-up people -- adult men and women -- never left off cheating and tormenting themselves and one another. It was not this spring morning which they considered sacred and important, not the beauty of God's world, given to all creatures to enjoy -- a beauty which inclines the heart to peace, to harmony and to love. No, what they considered sacred and important were their own devices for wielding power over each other.”

“I think... if it is true that there are as many minds as there are heads, then there are as many kinds of love as there are hearts.”

“When you understand that you will die to-morrow, if not to-day, and nothing will be left, then everything is so unimportant!... So one goes on living, amusing oneself with hunting, with work - anything so as not think of death”

“You and I are told increasingly that we have to choose between a left or a right. There is only an up or down: up to man's age-old dream -- the ultimate in individual freedom consistent with law and order -- or down to the ant heap of totalitarianism. And regardless of their sincerity, their humanitarian motives, those who would trade our freedom for security have embarked on this downward course.”

“My father taught me to work, but not to love it. I never did like to work, and I don't deny it. I'd rather read, tell stories, crack jokes, talk, laugh -- anything but work.”

“But what can I do?' - I answer those who speak thus. - '... must I therefore not point out the evil which I clearly, unquestionably see?”
