I considered that Mr. Keble met this difficulty by ascribing the firmness of assent which we give to religious doctrine, not to the probabilities which introduced it, but to the living power of faith and love which accepted it. In matters of religion, he seemed to say, it is not merely probability which makes us intellectually certain, but probability as it is put to account by faith and love. It is faith and love which give to probability a force which it has not in itself. Faith and love are directed towards an Object; in the vision of that Object they live; it is that Object, received in faith and love, which renders it reasonable to take probability as sufficient for internal conviction. Thus the argument from Probability, in the matter of religion, became an argument from Personality, which in fact is one form of the argument from Authority.
In illustration, Mr. Keble used to quote the words of the Psalm: "I will guide thee with mine _eye_. Be ye not like to horse and mule, which have no understanding; whose mouths must be held with bit and bridle, lest they fall upon thee." This is the very difference, he used to say, between slaves, and friends or children. Friends do not ask for literal commands; but, from their knowledge of the speaker, they understand his half-words, and from love of him they anticipate his wishes. Hence it is, that in his Poem for St. Bartholomew's Day, he speaks of the "Eye of God's word;" and in the note quotes Mr. Miller, of Worcester College, who remarks in his Bampton Lectures, on the special power of Scripture, as having "this Eye, like that of a portrait, uniformly fixed upon us, turn where we will." The view thus suggested by Mr. Keble, is brought forward in one of the earliest of the "Tracts for the Times." In No. 8 I say, "The Gospel is a Law of Liberty. We are treated as sons, not as servants; not subjected to a code of formal commandments, but addressed as those who love God, and wish to please Him."
I did not at all dispute this view of the matter, for I made use of it myself; but I was dissatisfied, because it did not go to the root of the difficulty. It was beautiful and religious, but it did not even profess to be logical; and accordingly I tried to complete it by considerations of my own, which are to be found in my University Sermons, Essay on Ecclesiastical Miracles, and Essay on Development of Doctrine. My argument is in outline as follows: that that absolute certitude which we were able to possess, whether as to the truths of natural theology, or as to the fact of a revelation, was the result of an _assemblage_ of concurring and converging probabilities, and that, both according to the constitution of the human mind and the will of its Maker; that certitude was a habit of mind, that certainty was a quality of propositions; that probabilities which did not reach to logical certainty, might suffice for a mental certitude; that the certitude thus brought about might equal in measure and strength the certitude which was created by the strictest scientific demonstration; and that to possess such certitude might in given cases and to given individuals be a plain duty, though not to others in other circumstances:--
