Such a definition as this would in a way be defensible. Religion, whatever it is, is a man’s total reaction upon life, so why not say that any total reaction upon life is a religion? Total reactions are different from casual reactions, and total attitudes are different from usual or professional attitudes. To get at them you must go behind the foreground of existence and reach down to that curious sense of the whole residual cosmos as an everlasting presence, intimate or alien, terrible or amusing, lovable or odious, which in some degree everyone possesses. This sense of the world’s presence, appealing as it does to our peculiar individual temperament, makes us either strenuous or careless, devout or blasphemous, gloomy or exultant, about life at large; and our reaction, involuntary and inarticulate and often half unconscious as it is, is the completest of all our answers to the question, “What is the character of this universe in which we dwell?” It expresses our individual sense of it in the most definite way. Why then not call these reactions our religion, no matter what specific character they may have? Non-religious as some of these reactions may be, in one sense of the word “religious,” they yet belong to the general sphere of the religious life , and so should generically be classed as religious reactions. “He believes in No-God, and he worships him,” said a colleague of mine of a student who was manifesting a fine atheistic ardor; and the more fervent opponents of Christian doctrine have often enough shown a temper which, psychologically considered, is indistinguishable from religious zeal.
But so very broad a use of the word “religion” would be inconvenient, however defensible it might remain on logical grounds. There are trifling, sneering attitudes even towards the whole of life; and in some men these attitudes are final and systematic. It would strain the ordinary use of language too much to call such attitudes religious, even though, from the point of view of an unbiased critical philosophy, they might conceivably be perfectly reasonable ways of looking upon life. Voltaire, for example, writes thus to a friend, at the age of seventy-three:
