“no sort of duplicity can long flourish without the help of vocal falsehoods”

Vol. 2 "On Philosophy and the Intellect" as translated in Essays and Aphorisms (1970), as translated by R. J. Hollingdale
Parerga and Paralipomena (1851), Counsels and Maxims
Context: Talent works for money and fame; the motive which moves genius to productivity is, on the other hand, less easy to determine. It isn’t money, for genius seldom gets any. It isn’t fame: fame is too uncertain and, more closely considered, of too little worth. Nor is it strictly for its own pleasure, for the great exertion involved almost outweighs the pleasure. It is rather an instinct of a unique sort by virtue of which the individual possessed of genius is impelled to express what he has seen and felt in enduring works without being conscious of any further motivation. It takes place, by and large, with the same sort of necessity as a tree brings forth fruit, and demands of the world no more than a soil on which the individual can flourish.

Variant: It is one of the beautiful compensations of life that no man can sincerely try to help another without helping himself.

Context: Every observer has noted that the younger the child, the less sense he has of his own ego. From the intellectual point of view, he does not distinguish between external and internal, subjective and objective. From the point of view of action, he yields to every suggestion, and if he does oppose to other people's wills — a certain negativism which has been called "the spirit of contradiction" — this only points to his real defenselessness against his surroundings. A strong personality can maintain itself without the help of this particular weapon. The adult and the older child have complete power over him. They impose their opinions and their wishes, and the child accepts them without knowing that he does so. Only — and this is the other side of the picture — as the child does not dissociate his ego from the environment, whether physical or social, he mixes into all his thoughts and all his actions, ideas and practices that are due to the intervention of his ego and which, just because he fails to recognize them as subjective, exercise a check upon his complete socialization. From the intellectual point of view, he mingles his own fantasies with accepted opinions, whence arise pseudo lies (or sincere lies), syncretism, and all the features of child thought. From the point of view of action, he interprets in his own fashion the examples he has adopted, whence the egocentric form of play we were examining above. The only way of avoiding these individual refractions would lie in true cooperation, such that both child and senior would each make allowance for his own individuality and for the realities that were held in common.

Variant: Pointless, needless suffering and pain? I don’t suppose it would help if I told you that was the way life is. The good suffer, the evil flourish, and all that is mortal passes away.

Nothing If Not Critical (1991)

Interview with Mark Shapiro (2000)
Context: It's more difficult, you know, to bring about positive change than it is to make money. It's much easier to make money, because it's a much easier way to measure success — the bottom line. When it comes to social consequences, they've got all different people acting in different ways, very difficult to even have a proper criterion of success. So, it's a difficult task. Why not use an entrepreneurial, rather than a bureaucratic, approach. As long as people genuinely care for the people they're trying to help, they can actually do a lot of good.

Is there any hope in education?

Context: In truth, mankind cannot be saved from without, by schoolmasters or any other sort of masters: it can only be lamed and enslaved by them. It is said that if you wash a cat it will never again wash itself. This may or may not be true: what is certain is that if you teach a man anything he will never learn it; and if you cure him of a disease he will be unable to cure himself the next time it attacks him.
