The author writes: In this book I have attempted to draw out, in English, arguments that bear on the existence and knowableness of God. By so doing, I do not pretend to offer to the reader anything new; I have neither invented nor discovered the arguments. In their general outlines they have been before the human mind during all the ages. My only aim has been to show that, in the warfare with infidelity, those arguments are as available at present as in any period of the past, and that as weapons of pefence they need only, as it were, to be refurbished anew, that they may be perfectly well fitted for modern use. To give to the reasoning greater point, and to answer objections on different subjects, I have cast much of the book into discussions. In these the scenic part is altogether imaginary. Places, time, and persons, I have feigned, in order vividly to formulate doctrines which were my principal, I may say, my only concern. Besides the authors quoted in the work, there are others whose suggestions on various topics have helped me. There being question of the fundamental truth of a1l truths, I sought light wheresoever I thought I might find it, and deemed it not unseemly to help my weakness with the strength of those who in the same grec t cause fought valiantly against the infidel. If this book will give security to some souls, and in any measure contribute to stem the tide of infidelity, the author shall consider himself amply rewarded for his labor.
