The Circle of Zero by Stanley G. Weinbaum

_If there were a mountain a thousand miles high and every thousand years a bird flew over it, just brushing the peak with the tip of its wing, in the course of inconceivable eons the mountain would be worn away. Yet all those ages would not be one second to the length of eternity_.

I don't know what philosophical mind penned the foregoing, but the words keep recurring to me since last I saw old Aurore de Neant, erstwhile professor of psychology at Tulane. When, back in '24, I took that course in Morbid Psychology from him, I think the only reason for taking it at all was that I needed an eleven o'clock on Tuesdays and Thursdays to round out a lazy program.
