“Revenge is not an ignoble motive, when it works to a productive end.”

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.

Context: Talent works for money and fame; the motive which moves genius to productivity is, on the other hand, less easy to determine. It isn’t money, for genius seldom gets any. It isn’t fame: fame is too uncertain and, more closely considered, of too little worth. Nor is it strictly for its own pleasure, for the great exertion involved almost outweighs the pleasure. It is rather an instinct of a unique sort by virtue of which the individual possessed of genius is impelled to express what he has seen and felt in enduring works without being conscious of any further motivation. It takes place, by and large, with the same sort of necessity as a tree brings forth fruit, and demands of the world no more than a soil on which the individual can flourish.
