“The past is always with us, for it feeds the present.”

Il piacere è sempre o passato o futuro, non mai presente.
29th September 1823, Festival of Saint Michael the Archangel.

The Golden Man (1954)
Context: "He can look ahead. See what's coming. He can — prethink. Let's call it that. He can see into the future. Probably he doesn't perceive it as the future."
"No," Anita said thoughtfully. "It would seem like the present. He has a broader present. But his present lies ahead, not back. Our present is related to the past. Only the past is certain, to us. To him, the future is certain. And he probably doesn't remember the past, any more than any animal remembers what happened."
"As he develops," Baines said, "as his race evolves, it'll probably expand its ability to prethink. Instead of ten minutes, thirty minutes. Then an hour. A day. A year. Eventually they'll be able to keep ahead a whole lifetime. Each one of them will live in a solid, unchanging world. There'll be no variables, no uncertainty. No motion! They won't have anything to fear. Their world will be perfectly static, a solid block of matter."
"And when death comes," Anita said, "they'll accept it. There won't be any struggle; to them, it'll already have happened."

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.
