Man's respect for the imponderables varies according to his mental constitution and environment. Through certain modes of thought and training it can be elevated tremendously, yet there is always a limit. The man or nation of high culture may acknowledge to great lengths the restraints imposed by conventions and honour, but beyond a certain point primitive will or desire cannot be curbed. Denied anything ardently desired, the individual or state will argue and parley just so long — then, if the impelling motive be sufficiently great, will cast aside every rule and break down every acquired inhibition, plunging viciously after the object wished; all the more fantastically savage because of previous repression.
At the Root (1918)
