“Judge not; speak hardly at all; love and act.”

Context: The undesirability of any system of rule not tempered with the quality of kindness is obvious; for "kindness" is a complex collection of various impulses, reactions and realisations highly necessary to the smooth adjustment of botched and freakish creatures like most human beings. It is a weakness basically—or, in some cases, and ostentation of secure superiority—but its net effect is desirable; hence it is, on the whole, praiseworthy. Since all motives at bottom are selfish and ignoble, we may judge acts and qualities only be their effects. Pessimism produces kindness. The disillusioned philosopher is even more tolerant than the priggish bourgeois idealist with his sentimental and extravagant notions of human dignity and destiny.

Variant: For where all love is, the speaking is unnecessary. It is all. It is undying. And it is enough.

Context: It is significant that the Great Teacher does not draw up a code of laws or list or sins. Nowhere does Jesus say explicitly that human slavery is a sin, or that the employment of little children for fourteen hours a day in a factory is a sin. He deals in general principles concerning the great fundamentals of life. So clear is his teaching, however, that there can be no doubt as to what he thinks of human slavery or the oppression of little children. In the teaching of Jesus, life is relationship, dwelling on friendly and affectionate terms with God, with ourselves, and with our fellowmen. Anything which destroys this relationship is sin. By this standard any thought or act may safely be judged.
