A merely pious attitude whose basis is blind faith and whose technique is simple prayer makes a good beginning yet is only a beginning. For the conditions through which we have to pass, the experiences which life ordains, bring about in the course of reincarnations a questioning which only philosophy can satisfy in the end. The Jew whose piety is mocked by the slaughter of six million of his co-religionists, the Hindus and Muhammedans whose meditations or prayers are interrupted by riots which remove another million from earth's scene, must sooner or later come to realize that faith is not enough, and that knowledge must be acquired to supplement it, not to supplant it. A refined understanding of cosmic purposes and cosmic laws is also needed. They find that sentimentality does not save them in their hour of need.
