“As the months of agony advanced, there was bred in the warring peoples a genuine and even passionate will for peace and a united world. Out of the conflict of the tribes arose, at least for a while, a spirit loftier than tribalism. But this fervour lacked as yet clear guidance, lacked even the courage of conviction.”

Context: The opinions that are held with passion are always those for which no good ground exists; indeed the passion is the measure of the holder’s lack of rational conviction. Opinions in politics and religion are almost always held passionately.

Sonnet XXX from Fatal Interview (1931)
Context: Love is not all: it is not meat nor drink
Nor slumber nor a roof against the rain;
Nor yet a floating spar to men that sink
And rise and sink and rise and sink again;
Love can not fill the thickened lung with breath,
Nor clean the blood, nor set the fractured bone;
Yet many a man is making friends with death
Even as I speak, for lack of love alone.
