Science never corroborates a spiritual truth without illuminating it. The threshold of Eternity is a place where many shadows meet. And the light of Science here, where everything is so dark, is welcome a thousand times. Many men would be religious if they knew where to begin; many would be more religious if they were sure where it would end. It is not indifference that keeps some men from God, but ignorance. "Good Master, what must I do to inherit Eternal Life?" is still the deepest question of the age. What is Religion? What am I to believe? What seek with all my heart and soul and mind?--this is the imperious question sent up to consciousness from the depths of being in all earnest hours; sent down again, alas, with many of us, time after time, unanswered. Into all our thought and work and reading this question pursues us. But the theories are rejected one by one; the great books are returned sadly to their shelves, the years pass, and the problem remains unsolved. The confusion of tongues here is terrible. Every day a new authority announces himself. Poets, philosophers, preachers, try their hand on us in turn. New prophets arise, and beseech us for our soul's sake to give ear to them--at last in an hour of inspiration they have discovered the final truth. Yet the doctrine of yesterday is challenged by a fresh philosophy to-day; and the creed of to-day will fall in turn before the criticism of to-morrow. Increase of knowledge increaseth sorrow. And at length the conflicting truths, like the beams of light in the laboratory experiment, combine in the mind to make total darkness.
