When in the fifth century the Roman Empire fell at the hands of the barbarians, rational medicine ceased altogether in Europe. Although the Christian religion survived, the Christian theology of that time denied liberty of conscience and taught superstitions and dogma. It was bitterly hostile to the scientific spirit. All knowledge necessary to man's salvation, physical as well as spiritual, was to be found in the Bible as the Church interpreted the Bible. Since the teachings of the Church were supposed to be sufficient for all needs, there was no excuse for observations and experimental investigations. The inquisitive spirit was wholly suppressed, the rigorous methods of Greek logic were for many centuries lost from European civilization, and intelligent thought was replaced by revelation, speculation, tradition, and subservience to the written word of the Bible, to the writings of saints, and later, in medical matters, to the work of Galen. The theological beliefs of the time became the controlling influence in Western civilization.

There has never been any religious crisis of this kind before, and any attempt at exact comparisons with the past are here bound to be misleading and distorting. Even the extreme assailant of pagan religions, like Lucretius, had no basis for the critical attitude as the contemporary sceptic. The bitter attack of Lucretius upon supernatural religion was based mainly upon assumptions and intuitions, as incapable of proof at the time as were the most extreme pietistic views of his age. Today the situation has been profoundly altered. Contemporary science, especially astrophysics, renders the whole set of assumptions underlying the anthropomorphic and geocentric supernaturalism of the past absolutely archaic and preposterous. Our scientific knowledge has undermined the most precious tales in the holy books of all peoples. The development of biblical criticism has discredited the dogma of direct revelation and unique nature of the Hebrew Bible. Textual scholarship has been equally devastating to the sacred scriptures which form the literary basis of the other world religions. It avails one nothing to deny these things, for they are actually undeniable. We must face the implied intellectual revolution honestly and see what is to be done about it.

To be thoroughly religious, one must, I believe, be sorely disappointed. One's faith in God increases as one's faith in the world decreases. The happier the man, the farther he is from God.

It is important that the truth be known. Is religion, is church membership a help to virtue? The careless will answer without hesitation, "Yes!" Of course. The statistics, when they are not smothered, cry, "No!"

On the basis of biological, sociological, and historical knowledge, we should recognize that the individual self is subject to death and decay, but the sum total of individual achievement, for better or for worse, lives on in the immortality of the Larger Self; that to live for the sake of the species and posterity is religion of the highest kind; and that those religions which seek a future life either in Heaven or in the Pure Land, are selfish religions.
