“Knowing Yourself - The true in the false, gradually strips away all self-delusion until all that remains is pure being.”

Outline of a Morality Without Obligation or Sanction https://www.marxists.org/archive/guyau/1885/morality.htm (1885).
Context: A third equivalent of duty is borrowed from sensibility and not, like the preceding, from intelligence and activity. It’s the growing fusion of sensibilities, and the ever increasing sociable character of elevated pleasures, from which results a kind of duty or superior necessity which pushes us naturally and rationally towards others. By virtue of evolution, our pleasures grow and become increasingly impersonal; we cannot experience enjoyment within our selves as if on a deserted isle. Our milieu, to which we better adapt ourselves every day, is human society, and we can no more be happy outside of this milieu than we can breathe outside the air. The purely selfish happiness of certain Epicureans is a chimera, an abstraction, an impossibility; the true human pleasures are all more or less social. Pure egoism, rather than being an affirmation of the self, is a mutilation of the self.

All and Everything: Views from the Real World (1973)
Context: There do exist enquiring minds, which long for the truth of the heart, seek it, strive to solve the problems set by life, try to penetrate to the essence of things and phenomena and to penetrate into themselves. If a man reasons and thinks soundly, no matter which path he follows in solving these problems, he must inevitably arrive back at himself, and begin with the solution of the problem of what he is himself and what his place is in the world around him. For without this knowledge, he will have no focal point in his search. Socrates’ words, “Know thyself” remain for all those who seek true knowledge and being.

Address to the United Nations (1963)
Context: On the question of racial discrimination, the Addis Ababa Conference taught, to those who will learn, this further lesson:
That until the philosophy which holds one race superior and another inferior is finally and permanently discredited and abandoned:
That until there are no longer first-class and second class citizens of any nation;
That until the colour of a man's skin is of no more significance than the colour of his eyes;
That until the basic human rights are equally guaranteed to all without regard to race;
That until that day, the dream of lasting peace and world citizenship and the rule of international morality will remain but a fleeting illusion, to be pursued but never attained;
And until the ignoble and unhappy regimes that hold our brothers in Angola, in Mozambique and in South Africa in subhuman bondage have been toppled and destroyed;
Until bigotry and prejudice and malicious and inhuman self-interest have been replaced by understanding and tolerance and good-will;
Until all Africans stand and speak as free beings, equal in the eyes of all men, as they are in the eyes of Heaven;
Until that day, the African continent will not know peace.
