Thus it is that these authorities have been weighed in the balances and found wanting. This is a marvelous age, an age of unsurpassed invention and discovery of truth, but it is not the _ne plus ultra_ of human wisdom--if we are to take any lessons from the past ages. The wave theory of sound, which has been regarded as a settled scientific fact since the days of Pythagorean, is now vigorously attacked, and the adherents to the orthodox ground will have to rally their forces and reconsider their proofs, if they save the theory from slumbering among the follies of the past. In the past few years the world has been startled by the bold theory of evolution, as advocated by Darwin, Haeckel, Huxley and others. Many have felt uneasy about the foundations of our faith. But such alarm is all premature. The glaring contradictions of one another of these modern apostles of a "gospel of dirt," and their self-stultification, are enough to convince any thoughtful reader, that if the race has not developed from apes, a few of them bear marks of descent from asses! The credulity of this class of men is simply marvelous. They can believe that a moneron can be developed into a man, but can not believe in a miracle! Their wonderful development of a moneron into a man terminates with the boundary line of time, and thus the _ne plus ultra_ is reached of their "infinite progression!" In order to a proper appreciation of the present life, we must be deeply impressed with the nature of that which lies beyond. No one can well spend the present life who does not spend it in view of the life to come. Man must properly appreciate himself before he can live in harmonious relations with his being. No man can have that appreciation of himself essential to a true life, who believes that his ancestors were monerons and mud-turtles!
