spirit to return to its true rest and centre--the struggle to "find Him" who is so intimately near to every human heart, and who has never ceased to be the want of the human race. The philosophies of the ancient world were the earnest effort of human reason to reconcile the finite and the infinite, the human and the Divine, the subject and God. An overruling Providence, which makes even the wrath of man to praise Him, took up all these sincere, though often mistaken, efforts into his own plan, and made them sub-serve the purpose of redemption. They aided in developing among the nations "the desire of salvation," and in preparing the world for the advent of the Son of God. The entire course and history of Divine providence, in every nation, and in every age, has been directed towards the one grand purpose of "reconciling all things to Himself." Christianity, as a comprehensive scheme of reconciliation, embracing "all things," can not, therefore, be properly studied apart from the ages of earnest thought, of profound inquiry, and of intense religious feeling which preceded it. To despise the religions of the ancient world, to sneer at the efforts and achievements of the old philosophers, or even to cut them off in thought from all relation to the plans and movements of that Providence which has cared for, and watched over, and pitied, and guided all the nations of the earth, is to refuse to comprehend Christianity itself. The author is not indifferent to the possibility that his purpose may be misconceived. The effort may be regarded by many conscientious and esteemed theologians with suspicion and mistrust. They can not easily emancipate themselves from the ancient prejudice against speculative thought. Philosophy has always been regarded by them as antagonistic to Christian faith. They are inspired by a commendable zeal for the honor of dogmatic theology. Every essay towards a profounder conviction, a broader faith in the unity of all truth, is branded with the opprobrious name of "rationalism." Let us not be terrified by a harmless word. Surely religion and right reason must be found in harmony. The author believes, with Bacon, that "the foundation of all religion is right reason." The abnegation of reason is not the evidence of faith, but the confession of despair. Sustained by these convictions, he submits this humble contribution to theological science to the thoughtful consideration of all lovers of Truth, and of Christ, the fountain of Truth. He can sincerely ask upon it the blessing of Him in whose fear it has been written, and whose cause it is the purpose of his life to serve. The second series, on "Christianity and Modern Thought," is in an advanced state of preparation for the press.
