“To find the cause of our ills in something outside ourselves, something specific that can be spotted and eliminated, is a diagnosis that cannot fail to appeal. To say that the cause of our troubles is not in us but in the Jews, and pass immediately to the extermination of the Jews, is a prescription likely to find a wide acceptance.”

1900s, The Varieties of Religious Experience (1902)
Context: The ideal power with which we feel ourselves in connection, the 'God' of ordinary men, is, both by ordinary men and by philosophers, endowed with certain of those metaphysical attributes which in the lecture on philosophy I treated with such disrespect. He is assumed as a matter of course to be 'one and only,' and to be 'infinite'; and the notion of many finite gods is one which hardly any one thinks it worth while to consider, and still less to uphold. Nevertheless, in the interests of intellectual clearness, I feel bound to say that religious experience, as we have studied it, cannot be cited as unequivocally supporting the infinitist belief. The only thing that it unequivocally testifies to is that we can experience union with something larger than ourselves and in that union find our greatest peace. Philosophy, with its passion for unity, and mysticism with its monoideistic bent, both 'pass to the limit' and identify the something with a unique God who is the all-inclusive soul of the world. Popular opinion, respectful to their authority, follows the example which they set.
