Within these two words — being and becoming, your whole life is contained. Being is enlightenment, becoming is ignorance.

The Almost Perfect State (1921)
Context: We have always been compelled, and we shall be compelled for many years to come, to be prudent, cautious, staid, sober, conservative, industrious, respectful of established institutions, a model citizen. We have not liked it, but we have been unable to escape it. Our mind, our logical faculties, our observation, inform us that the conservatives have the right side of the argument in all human affairs. But the people whom we really prefer as associates, though we do not approve their ideas, are the rebels, the radicals, the wastrels, the vicious, the poets, the Bolshevists, the idealists, the nuts, the Lucifers, the agreeable good-for-nothings, the sentimentalists, the prophets, the freaks. We have never dared to know any of them, far less become intimate with them.
