“I never believed, as many Marxists professed to do, that normative principles were irrelevant to the socialist movement, that, since the movement was of oppressed people fighting for their own liberation, there was no room or need for specifically moral inspiration in it. I thought no such thing partly for the plain reason that I observed enormous selfless dedication among the active communists who surrounded me in my childhood, and partly for the more sophisticated reason that the self-interest of any oppressed producer would tell him to stay at home, rather than to risk his neck in a revolution whose success or failure would be anyhow unaffected by his participation in it. Revolutionary workers and, a fortiori, bourgeois fellow-travellers without a particular material interest in socialism, must perforce be morally inspired.”

Ma vie entière est un tissu de contrastes apparents avec mes principes. Je n'aime point les Princes, et je suis attaché à une Princesse et à un Prince. On me connaît des maximes républicaines, et plusieurs de mes amis sont revêtus de décorations monarchiques. J'aime la pauvreté volontaire, et je vis avec des gens riches. Je fuis les honneurs, et quelques-uns sont venus à moi. Les lettres sont presque ma seule consolation, et je ne vois point de beaux esprits, et ne vais point à l'Académie. Ajoutez que je crois les illusions nécessaires à l'homme, et je vis sans illusion; que je crois les passions plus utiles que la raison, et je ne sais plus ce que c'est que les passions, etc.

Variant translation: When all your judgements are based on your own wisdom, you tend towards selfishness and fail by straying from the right path. Your own judgements are narrow minded and have no persuasive power or growth for others. It is best to consult a wise man when a fit decision does not occur to you. A wise man is a fair judge from an objective point of view. He is passing judgement for the benefit of others, not for his own sake. A judgement passed using only one's own wisdom is just like thrusting a stick into the ground and expecting it to grow!
Hagakure (c. 1716)
Context: It is difficult for a fool's habits to change to selflessness.... Because we do most things relying only on our own sagacity we become self-interested, turn our backs on reason, and things do not turn out well. As seen by other people this is sordid, weak, narrow and inefficient. When one is not capable of true intelligence, it is good to consult with someone of good sense. An advisor will fulfill the Way when he makes a decision by selfless and frank intelligence because he is not personally involved. This way of doing things will certainly be seen by others as being strongly rooted. It is, for example, like a large tree with many roots. One man's intelligence is like a tree that has been simply stuck in the ground.
We learn about the sayings and deeds of the men of old in order to entrust ourselves to their wisdom and prevent selfishness. When we throw off our own bias, follow the sayings of the ancients, and confer with other people, matters should go well and without mishap.
