“To-day alone was real. Never was man brought into contact with reality save through the evanescent emotions and sensations of that single moment, that infinitesimal fraction of a second, which was passing now — and it was in the insignificance of this moment, precisely, that religious persons must believe.”

Context: To-day alone was real. Never was man brought into contact with reality save through the evanescent emotions and sensations of that single moment, that infinitesimal fraction of a second, which was passing now — and it was in the insignificance of this moment, precisely, that religious persons must believe. So ran the teachings of all dead and lingering faiths alike. Here was, perhaps, only another instance of mankind's abhorrence of actualities; and man's quaint dislike of facing reality was here disguised as a high moral principle. That was why all art, which strove to make the sensations of a moment soul-satisfying, was dimly felt to be irreligious. For art performed what religion only promised.
