It has become therefore of great importance to recognise if possible the lines of least resistance along the mighty stream of religious enthusiasm, and provide that its energies shall not be destructive but conservative of human welfare. At present the most conservative force in the earth is ignorance: were the suffering masses of the world to discover, suddenly and universally, that the old creeds are fictions, their evils not providential, their heavenly hopes vain, every nation would be filled with convulsions. Fortunately the sun is not shot up into the heavens. But enlightenment progresses rapidly, and we have begun none too soon turning the rising flood of light and fire into the human channels long obstructed by sanctified inhumanities. Mr. Call’s little book, which I hope will find publication and wide circulation in America, sums up succinctly and cogently the present religious situation, and the steps by which it has been reached. It remains for us all to sweep the new horizon with eye and telescope, to compare our observations and to catch the first ray of the star that shall point wise men to the new incarnation. To my own mind this book is one of the many signs and promises that the divine will be steadily merged into and identified with the human. Not with humanity as an objective and historical entity, as Comte believed, but with the distinctive characteristics of humanity, the supreme qualities of reason and love: this will become the ideal of the reasoners and the lovers; it will then become the creating Word, instructing all; it will finally be made flesh and dwell among us, and all shall behold in it the glory of the kingdom of Man. MONCURE D. CONWAY. FACTS AND MENTAL SYMBOLS. I perceive from Dr. Carus’s answer to my letter in No. 3 Vol. I of _The Monist_, that amid all the agreement of our mutual endeavors a material difference of opinion exists between us on an important question of special character. As I was not successful in rendering my thought clear on this point, I shall endeavor on the present occasion to explain _what_ it was that forced me to abandon my old position (1863), which is very near to that of Dr. Carus, and to assume a new one. The supposition that our difference of opinion is merely apparent and can be adjusted by a precise agreement as to the terms employed is a very natural one in philosophical discussions. It is hardly tenable, though, when the divergent views in question arise _subsequently_ to one another in the _same_ person.
