Who said “Cycle tracks will abound in Utopia.”?

“Let a man find himself, in distinction from others, on top of two wheels with a chain -- at least in a poor country like Russia -- and his vanity begins to swell out like his tires. In America it takes an automobile to produce this effect.”

“Consider a man riding a bicycle. Whoever he is, we can say three things about him. We know he got on the bicycle and started to move. We know that at some point he will stop and get off. Most important of all, we know that if at any point between the beginning and the end of his journey he stops moving and does not get off the bicycle he will fall off it. That is a metaphor for the journey through life of any living thing, and I think of any society of living things.”

“If all feeling for grace and beauty were not extinguished in the mass of mankind at the actual moment, such a method of locomotion as cycling could never have found acceptance; no man or woman with the slightest aesthetic sense could assume the ludicrous position necessary for it.”

“Our true nationality is mankind.”

“Cynicism is humour in ill health.”

“Moral indignation is jealousy with a halo.”

“The crisis of yesterday is the joke of tomorrow.”

“Fools make researches and wise men exploit them.”

“Adapt or perish, now as ever, is Nature's inexorable imperative.”
