Shall we take seriously this eloquent enunciation of faith in humility, in self-denial, in fraternal love, or shall we regard it only as a beautiful and peaceful phase in the career of a man of genius who, after the storm and stress of a life of sin and suffering, has turned back to the ideals of youth and innocence, and sought to make them once more the objects of desire? Fanaticism, do you say? Ah, yes; but did not Jesus and his disciples practise just such fanaticism as this? Does any one deny that all that is best in this modern world (and there is so much of the best, after all), that all that is best has come from the great moral impulse generated by a little group of fanatics in an obscure corner of Asia eighteen centuries ago? That impulse we still feel, in spite of all the obstructions that have been put in its way to nullify its action; and if any would seek for strength from the primary source of power, who shall say him nay? And so although we may smile at the artlessness of this Russian evangelist in his determination to find in the gospels the categorical imperative of self-renunciation, although we may regard with wonder the magnificent audacity of his exegetical speculations, we cannot refuse to admire a faith so sincere, so intense, and, in many respects, so elevating and so noble. HUNTINGTON SMITH. DORCHESTER, MASS., Nov. 19, 1885. INTRODUCTION. I HAVE not always been possessed of the religious ideas set forth in this book. For thirty-five years of my life I was, in the proper acceptation of the word, a nihilist,--not a revolutionary socialist, but a man who believed in nothing. Five years ago faith came to me; I believed in the doctrine of Jesus, and my whole life underwent a sudden transformation. What I had once wished for I wished for no longer, and I began to desire what I had never desired before. What had once appeared to me right now became wrong, and the wrong of the past I beheld as right. My condition was like that of a man who goes forth upon some errand, and having traversed a portion of the road, decides that the matter is of no importance, and turns back. What was at first on his right hand is now on his left, and what was at his left hand is now on his right; instead of going away from his abode, he desires to get back to it as soon as possible. My life and my desires were completely changed; good and evil interchanged meanings. Why so? Because I understood the doctrine of Jesus in a different way from that in which I had understood it before. It is not my purpose to expound the doctrine of Jesus; I wish only to tell how it was that I came to understand what there is in this doctrine that is simple, clear, evident, indisputable; how I understand that part of it which appeals to all men, and how this understanding refreshed my soul and gave me happiness and peace.
