Our own age, it may be said, possesses a philosophic method unknown to the ancient world. The old metaphysical systems failed; but we have relaid the foundations of life and thought upon the solid ground of nature. Modern culture rests upon a basis of positive and demonstrated knowledge, whose value is independent of religious belief. Scientific discovery has put us in command of material forces that secure the race against any such relapse as that which took place in the overthrow of the Græco-Roman civilization. _Pessimism_ answers these pretensions made for physical science by her idolaters. Pessimism is the nemesis of irreligious thought. It creeps like a slow palsy over the highest and ablest minds that reject the Christian hope. What avails it to yoke steam to our chariot, if black care still sits behind the rider? to wing our thoughts with the lightning, if those thoughts are no happier or worthier than before? “Civilization contains within itself the elements of a fresh servitude. Man conquers the powers of nature, and becomes in turn their slave” (F. W. Robertson). Poverty grows gaunt and desperate by the side of lavish wealth. A new barbarism is bred in what science grimly calls the _proletariate_, a barbarism more vicious and dangerous than the old, that is generated by the inhuman conditions of life under the existing regime of industrial science. Education gives man quickness of wit and new capacity for evil or good; culture makes him more sensitive; refinement more delicate in his virtues or his vices. But there is no tendency in these forces as we see them now in operation, any more than in the classical discipline, to make nobler or better men. Secular knowledge supplies nothing to bind society together, no force to tame the selfish passions, to guard the moral interests of mankind. Science has given an immense impetus to the forces acting on civilized men; it cannot change or elevate their character. It puts new and potent instruments into our hands; but whether those instruments shall be tools to build the city of God or weapons for its destruction, is determined by the spirit of the wielders. In the midst of his splendid machinery, master of the planet’s wealth and lord of nature’s forces, the civilized man at the end of this boastful century stands with a dull and empty heart--without God. Poor creature, he wants to know whether “life is worth living”! He has gained the world, but lost his soul.
