Another "old" lecture, which I have just reread. . .& was especially struck by this paragraph, admittedly now taken out of context:

"This conflict of the centripetal and centrifugal forces, of which the so-called self is the centre, is the basis of morality. Broadly speaking, what is done for one's self is bad; what is done for some one else is good. Consciously or unconsciously, this idea lies at the foundation of all the highest moral teaching. The highest virtues are those that conduce to the extinction of terrestrial types. The struggle for existence is the struggle for terrestrial, that is, material existence. If a selfish man and an altruist are wrecked on a desert island with only food enough for one, the selfish man will survive. The penalty of altruism is extermination. Yet no one p. 47 would maintain for a moment that the altruist is not the higher type of man."
