Against Authority: Freedom and the Rise of Surveillance States (2014)
“Alongside of the rare cases of true conversation where there is a genuine interchange of opinions or commands, one can observe in children between 2 and 6 a characteristic type of pseudo-conversation or "collective monologue", during which the children speak only for themselves, although they wish to be in the presence of interlocutors who will serve as a stimulus. Now here again, each feels himself to be in communion with the group because he is inwardly addressing the Adult who knows and understands everything, but here again, each is only concerned with himself, for lack of having dissociated the "ego" from the "socius."”

Context: The inevitable hypocrisy, which is associated with the all the collective activities of the human race, springs chiefly from this source: that individuals have a moral code which makes the actions of collective man an outrage to their conscience. They therefore invent romantic and moral interpretations of the real facts, preferring to obscure rather than reveal the true character of their collective behavior. Sometimes they are as anxious to offer moral justifications for the brutalities from which they suffer as for those which they commit. The fact that the hypocrisy of man's group behavior... expresses itself not only in terms of self-justification but in terms of moral justification of human behavior in general, symbolizes one of the tragedies of the human spirit: its inability to conform its collective life to its individual ideals. As individuals, men believe they ought to love and serve each other and establish justice between each other. As racial, economic and national groups they take for themselves, whatever their power can command.

“Thus they are destitute of that very lovely and exquisitely natural friendship, which is an object of desire in itself and for itself, nor can they learn from themselves how valuable and powerful such a friendship is. For each man loves himself, not that he may get from himself some reward for his own affection, but because each one is of himself dear to himself. And unless this same feeling be transferred to friendship, a true friend will never be found; for a true friend is one who is, as it were, a second self.”
Ita pulcherrima illa et maxime naturali carent amicitia per se et propter se expetita nec ipsi sibi exemplo sunt, haec vis amicitiae et qualis et quanta sit. Ipse enim se quisque diligit, non ut aliquam a se ipse mercedem exigat caritatis suae, sed quod per se sibi quisque carus est. Quod nisi idem in amicitiam transferetur, verus amicus numquam reperietur; est enim is qui est tamquam alter idem.

Context: I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children; whose work serves the earth he lives on and from and with, and is therefore pleasurable and meaningful and unending; whose rewards are not deferred until "retirement," but arrive daily and seasonally out of the details of the life of their place; whose goal is the continuance of the life of the world, which for a while animates and contains them, and which they know they can never compass with their understanding or desire.
