“Humanity is old, civilization is new: the mesh of cogs is by no means smooth—and this is as it should be. Never should a man enter a building of glass or metal, or a spaceship, or a submarine, without a small shock of astonishment; never should he avoid an act of passion without a small sense of effort…. We of the Institute receive an intensive historical inculcation; we know the men of the past, and we have projected dozens of possible future variations, which, without exception, are repulsive. Man, as he exists now, with all his faults and vices, a thousand gloriously irrational compromises between two thousand sterile absolute—is optimal. Or so it seems to us who are men.”

Context: Mountains should be climbed with as little effort as possible and without desire. The reality of your own nature should determine the speed. If you become restless, speed up. If you become winded, slow down. You climb the mountain in an equilibrium between restlessness and exhaustion. Then, when you are no longer thinking ahead, each footstep isn't just a means to an an end but a unique event in itself. This leaf has jagged edges. This rock looks loose. From this place the snow is less visible, even though closer. These are things you should notice anyway. To live only for some future goal is shallow. It’s the sides of the mountain that sustain life, not the top. Here's where things grow. <!-- p. 205

Kalki : or The Future of Civilization (1929)
Context: The East and the West are not so sharply divided as the alarmists would make us believe. The products of spirit and intelligence, the positive sciences, the engineering techniques, the governmental forms, the legal regulations, the administrative arrangements, and the economic institutions are binding together peoples of varied cultures and bringing them into closer reciprocal contact. The world today is tending to function as one organism.
The outer uniformity has not, however, resulted in an inner unity of mind and spirit. The new nearness into which we are drawn has not meant increasing happiness and diminishing friction, since we are not mentally and spiritually prepared for the meeting. Maxim Gorky relates how, after addressing a peasant audience on the subject of science and the marvels of technical inventions, he was criticized by a peasant spokesman in the following words : "Yes, we are taught to fly in the air like birds, and to swim in the water like the fishes, but how to live on the earth we do not know."
Among the races, religions, and nations which live side by side on the small globe, there is not that sense of fellowship necessary for good life. They rather feel themselves to be antagonistic forces. Though humanity has assumed a uniform outer body, it is still without a single animating spirit. The world is not of one mind. … The provincial cultures of the past and the present have not always been loyal to the true interests of the human race. They stood for racial, religious, and political monopolies, for the supremacy of men over women and of the rich over the poor. Before we can build a stable civilization worthy of humanity as a whole, it is necessary that each historical civilization should become conscious of its limitations and it's unworthiness to become the ideal civilization of the world.

Variant: It is not even enough that the fortune should have been gained without doing damage to the community. We should only permit it to be gained and kept so long as the gaining and the keeping represent benefit to the community.
Context: We grudge no man a fortune which represents his own power and sagacity, when exercised with entire regard to the welfare of his fellows. Again, comrades over there, take the lesson from your own experience. Not only did you not grudge, but you gloried in the promotion of the great generals who gained their promotion by leading their army to victory. So it is with us. We grudge no man a fortune in civil life if it is honorably obtained and well used. It is not even enough that it should have been gained without doing damage to the community. We should permit it to be gained only so long as the gaining represents benefit to the community.
