Context: The laws of capitalism, blind and invisible to the majority, act upon the individual without his thinking about it. He sees only the vastness of a seemingly infinite horizon before him. That is how it is painted by capitalist propagandists, who purport to draw a lesson from the example of Rockefeller — whether or not it is true — about the possibilities of success.
The amount of poverty and suffering required for the emergence of a Rockefeller, and the amount of depravity that the accumulation of a fortune of such magnitude entails, are left out of the picture, and it is not always possible to make the people in general see this.

Variant: With every part you act, there must be a little of yourself in it. If there isn't, it's not acting. It's lying.

Context: The most worthwhile form of education is the kind that puts the educator inside you, as it were, so that the appetite for learning persists long after the external pressure for grades and degrees has vanished. Otherwise you are not educated; you are merely trained.

Context: It is not uncommon to hear a man who has become confused about what he should do in a particular situation complain about the unique nature of the situation, thinking that he could easily act if the situation were a great event with only one either/or. This is a mistake and a hallucination of the understanding. There is no such situation. The presence of the crucial either/or depends upon the individual’s own impassioned desire directed toward acting decisively, upon the individual’s own intrinsic competence, and therefore a competent man covets an either/or in every situation because he does not want anything more. But as soon as the individual no longer has essential enthusiasm in his passion but is spoiled by letting his understanding frustrate him every time he is going to act, he never in his life discovers the disjunction. And even if his penetrating, resourceful understanding is adequate for managing an entire household, he still has not had an understanding of his life in advance or in the moment of action, and it cannot be understood afterwords, either, because the action essentially did not take place, and the coherence of his life, became a garrulous continuation or a continued garrulity, a participial or infinitive phrase in which the subject must be understood or, more correctly, cannot be located at all because, as the grammarians say, the meaning does not make it clear for the simple reason that it lacks meaning. The whole thing becomes a flux, a blend of a little resolution and a little situation, a little prudence and a little courage, a little probability and a little faith, a little action and a little incident. Anyone who has made the fraudulent trade of getting abnormally good sense by losing the capacity to will and the passion to act is very inclined to stiffen his spinelessness with various and sundry predeliberations that feel their way ahead and various and sundry postmortem reinterpretations of what happened. Compared to this, an action is a brief something and apparently a poor something, yet it is in fact a definite something. The other is more splendid, but for all that it is a splendid shabbiness.
