92:3.3
Primitive religion is nothing more nor less than the struggle for material existence extended to embrace existence beyond the grave. The observances of such a creed represented the extension of the self-maintenance struggle into the domain of an imagined ghost-spirit world. But when tempted to criticize evolutionary religion, be careful. Remember, that is what happened; it is a historical fact. And further recall that the power of any idea lies, not in its certainty or truth, but rather in the vividness of its human appeal.
