“Without knowledge of what I am and why I am here, it is impossible to live, and since I cannot know that, I cannot live either. In an infinity of time, in an infinity of matter, and an infinity of space a bubble-organism emerges while will exist for a little time and then burst, and that bubble am I.”

“There are people who, on meeting a successful rival, no matter in what, are at once disposed to turn their backs on everything good in him, and to see only what is bad. There are people, on the other hand, who desire above all to find in that lucky rival the qualities by which he has outstripped them, and seek with a throbbing ache at heart only what is good.”

“The only thing that we know is that we know nothing, and that is the highest flight of human wisdom.”

“I have lived through much and now I think I have found what is needed for happiness. A quiet, secluded life in the country with possibility of being useful to people.”

“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.”

“... for nightinggales - we know - can’t live on fairytales.”

“Even in the valley of the shadow of death, two and two do not make six.”

“Germans are self-confident on the basis of an abstract notion—science, that is, the supposed knowledge of absolute truth. A Frenchman is self-assured because he regards himself personally, both in mind and body, as irresistibly attractive to men and women. An Englishman is self-assured, as being a citizen of the best-organized state in the world, and therefore as an Englishman always knows what he should do and knows that all he does as an Englishman is undoubtedly correct. An Italian is self-assured because he is excitable and easily forgets himself and other people. A Russian is self-assured just because he knows nothing and does not want to know anything, since he does not believe that anything can be known.”

“Every man, knowing to the smallest detail all the complexity of the conditions surrounding him, involuntarily assumes that the complexity of these conditions and the difficulty of comprehending them are only his personal, accidental peculiarity, and never thinks that others are surrounded by the same complexity as he is.”

“As soon as she had gone out, swift, swift light steps sounded on the parquet, and his bliss, his life, himself - what was best in himself, what he had so long sought and longed for - was quickly, so quickly approaching him. She did not walk but seemed, by some unseen force, to float to him. He saw nothing but her clear, truthful eyes, frightened by that same bliss of love that flooded his heart. Those eyes were shining nearer and nearer, blinding him with their light of love. She stopped close to him, touching him. Her hands rose and dropped on his shoulders.

“But every acquisition that is disproportionate to the labor spent on it is dishonest.”

“All is over...I have nothing but you, remember that.”

. “Freethinkers are those who are willing to use their minds without prejudice and without fearing to understand things that clash with their own customs, privileges, or beliefs. This state of mind is not common, but it is essential for right thinking...

“Teach French and unteach sincerity.”
