“Experience used to be called The Soul. Experience as invisibility of man to man is at the same time more evident than anything.”

First Tractate : The Animate and the Man, §3
The First Ennead (c. 250)

Dostoievsky’s barrack vows of “improvement” now appeared to him as a sacrilege. He experience which he underwent was much the same as Luther’s when he remembered with such unfeigned horror and disgust the vows which he had pronounced on entering the convent. P. 10

Context: Every time man makes a new experiment he always learns more. He cannot learn less. He may learn that what he thought was true was not true. By the elimination of a false premise, his basic capital wealth which in his given lifetime is disembarrassed of further preoccupation with considerations of how to employ a worthless time-consuming hypothesis. Freeing his time for its more effective exploratory investment is to give man increased wealth.

Source: The Politics of Experience (1967), Ch. 1 : Experience as evidence
Context: I cannot experience your experience. You cannot experience my experience. We are both invisible men. All men are invisible to one another. Experience used to be called The Soul. Experience as invisibility of man to man is at the same time more evident than anything. Only experience is evident. Experience is the only evidence. Psychology is the logos of experience. Psychology is the structure of the evidence, and hence psychology is the science of sciences.

1840s, Essays: First Series (1841), Compensation
Context: We feel defrauded of the retribution due to evil acts, because the criminal adheres to his vice and contumacy, and does not come to a crisis or judgment anywhere in visible nature. There is no stunning confutation of his nonsense before men and angels. Has he therefore outwitted the law? Inasmuch as he carries the malignity and the lie with him, he so far deceases from nature. In some manner there will be a demonstration of the wrong to the understanding also; but should we not see it, this deadly deduction makes square the eternal account.
Neither can it be said, on the other hand, that the gain of rectitude must be bought by any loss. There is no penalty to virtue; no penalty to wisdom; they are proper additions of being. In a virtuous action, I properly am; in a virtuous act, I add to the world; I plant into deserts conquered from Chaos and Nothing, and see the darkness receding on the limits of the horizon. There can be no excess to love; none to knowledge; none to beauty, when these attributes are considered in the purest sense. The soul refuses limits, and always affirms an Optimism, never a Pessimism.
His life is a progress, and not a station. His instinct is trust. Our instinct uses "more" and "less" in application to man, of the presence of the soul, and not of its absence; the brave man is greater than the coward; the true, the benevolent, the wise, is more a man, and not less, than the fool and knave. There is no tax on the good of virtue; for that is the incoming of God himself, or absolute existence, without any comparative. Material good has its tax, and if it came without desert or sweat, has no root in me, and the next wind will blow it away. But all the good of nature is the soul's, and may be had, if paid for in nature's lawful coin, that is, by labor which the heart and the head allow. I no longer wish to meet a good I do not earn, for example, to find a pot of buried gold, knowing that it brings with it new burdens. I do not wish more external goods, — neither possessions, nor honors, nor powers, nor persons. The gain is apparent; the tax is certain. But there is no tax on the knowledge that the compensation exists, and that it is not desirable to dig up treasure. Herein I rejoice with a serene eternal peace. I contract the boundaries of possible mischief. I learn the wisdom of St. Bernard, — "Nothing can work me damage except myself; the harm that I sustain I carry about with me, and never am a real sufferer but by my own fault."

Context: Man is constantly being assured that he has more power than ever before in history, but his daily experience is one of powerlessness. … If he is with a business organization, the odds are great that he has sacrificed every other kind of independence in return for that dubious one known as financial.

The Captive Mind (1953)
Context: Never has there been a close study of how necessary to a man are the experiences which we clumsily call aesthetic. Such experiences are associated with works of art for only an insignificant number of individuals. The majority find pleasure of an aesthetic nature in the mere fact of their existence within the stream of life. In the cities, the eye meets colorful store displays, the diversity of human types. Looking at passers-by, one can guess from their faces the story of their lives. This movement of the imagination when a man is walking through a crowd has an erotic tinge; his emotions are very close to physiological sensations.
