This is essentially an age of change. Things which have been established for centuries are no longer regarded as fixed. That which has been looked upon as absolute is now respectfully held to be uncertain. The foundations of old ideas are being disturbed and man finds that he has built upon sandy bottom. Much which in times past answered the human soul, now affords no satisfaction. It is plain that a revolution has commenced that will be far reaching and important in its actions and reactions. There is to be a general overhauling of matters secular and religious, political and social and a wholesale clearing out of old words and forms, of outgrown habits and customs, may be expected. The world of man is about to take account of stock and to have a universal comparison of estimates of values. Too long have we been subsisting upon the say-soes of our ancestors and taking their eyes and ears as infallible. For many years men have regarded all questions of religion as settled, and that the whole duty of this and future generations was to accept the conclusions of the past upon all religious matters. We do not understand how men ever came to regard such conclusions as final or how they came to expect the whole human race to receive them as the utmost of human knowledge. We do not look upon the questions of religion as settled, and the growing doubts of the infallibility of the common religious ideas demand that we reconsider these questions. To do this we have not to go into any theological discussion. No learned authorities are to be consulted to establish or refute any line of argument. No dictionary of terms is to be examined to settle the meanings of words. We have only to decide whether mankind had better facilities for observing and studying the phenomena of the universe in past times than we have to-day; whether their eyes and ears were better than ours, and their methods and opportunities for ascertaining the truth of things higher than those of this age. If men in the past had facilities inferior to ours for observing the phenomena of the universe, it would follow that their ideas of the universe would be inferior. Now, if we have superior ideas of the universe, ideas nearer the truth of things, why should we be expected to surrender these and hold ideas which are false? It seems to us that the questions of religion may be settled by deciding whether or not we are to believe our own eyes and ears and trust our own knowledge and experience. It is certain that if we can trust our senses and our knowledge, the old ideas of the universe, of the origin of earth, of life, of man, and of good and evil and the whole catalogue of religious things are incorrect; and if we accept them we do so contrary to our reason and understanding.
