Psychology · William James
I + E > P.
Thus not only our morality but our religion, so far as the latter is deliberate, depend on the effort which we can make. "_Will you or won't you have it so?_" is the most probing question we are ever asked; we are asked it every hour of the day, and about the largest as well as the smallest, the most theoretical as well as the most practical, things. We answer by _consents or non-consents_ and not by words. What wonder that these dumb responses should seem our deepest organs of communication with the nature of things! What wonder if the effort demanded by them be the measure of our worth as men! What wonder if the amount which we accord of it were the one strictly underived and original contribution which we make to the world!
