I have taken an instance, in which the matter which is submitted for examination and for assent, can hardly fail of being interesting to the minds employed upon it; but in many cases, even though the fact assented-to has a bearing upon action, it is not directly of a nature to influence the feelings or conduct, except of particular persons. And in such instances of certitude, the previous labour of coming to a conclusion, and that repose of mind which I have above described as attendant on an assent to its truth, often counteracts whatever of lively sensation the fact thus concluded is in itself adapted to excite; so that what is gained in depth and exactness of belief is lost as regards freshness and vigour. Hence it is that literary or scientific men, who may have investigated some difficult point of history, philosophy, or physics, and have come to their own settled conclusion about it, having had a perfect right to form one, are far more disposed to be silent as to their convictions, and to let others alone, than partisans on either side of the question, who take it up with less thought and seriousness. And so again, in the religious world, no one seems to look for any great devotion or fervour in controversialists, writers on Christian Evidences, theologians, and the like, it being taken for granted, rightly or wrongly, that such men are too intellectual to be spiritual, and are more occupied with the truth of doctrine than with its reality. If, on the other hand, we would see what the force of simple assent can be, viewed apart from its reflex confirmation, we have but to look at the generous and uncalculating energy of faith as exemplified in the primitive Martyrs, in the youths who defied the pagan tyrant, or the maidens who were silent under his tortures. It is assent, pure and simple, which is the motive cause of great achievements; it is a confidence, growing out of instincts rather than arguments, stayed upon a vivid apprehension, and animated by a transcendent logic, more concentrated in will and in deed for the very reason that it has not been subjected to any intellectual development. It must be borne in mind, that, in thus speaking, I am contrasting with each other the simple and the reflex assent, which together make up the complex act of certitude. In its complete exhibition keenness in believing is united with repose and persistence.
