"It is a significant fact that all religions, without one exception, hold that man is a degeneration of what he was, whether they clothe this in mythological words, or in the clear language of philosophy, or in the beautiful expressions of poetry. This is the one fact that comes out of every scripture and of every mythology that the man that is, is a degeneration of what he was. This is the kernel of truth within the story of Adam's fall in the Jewish scripture. This is again and again repeated in the scriptures of the Hindus; the dream of a period which they call the Age of Truth, when no man died unless he wished to die, when he could keep his body as long as he liked, and his mind was pure and strong. There was no evil and no misery; and the present age is a corruption of that state of perfection. Side by side with this, we find the story of the deluge everywhere. That story itself is a proof that this present age is held to be a corruption of a former age by every religion. It went on becoming more and more corrupt until the deluge swept away a large portion of mankind, and again the ascending series began. It is going up slowly again to reach once more that early state of purity. You are all aware of the story of the deluge in the Old Testament. The same story was current among the ancient Babylonians, the Egyptians, the Chinese, and the Hindus."
