In less than a geological epoch/said Henry Mencken

Henry Louis Mencken (1880-1959), American editor, author and critic.

Mencken writes me (his letter dated March 1st). "Certainly the fact that a professional politician makes a mess of something is no proof that it is intrinsically unsound. Nevertheless, I believe that all schemes of monetary reform collide inevitably with the nature of man in the mass. He can't be convinced in anything less than a geological epoch."

Above statement does not invalidate geological process.
