that _every truth is in complete harmony with every other truth_; and hold with no less tenacity to the principle that the human intellect is true. And what is the true premiss which through an irrefutable logic will give us a satisfactory, a true, an undoubted conclusion. This. A plurality of terms is _not_ the necessary condition of intelligence; but objects which are pure, simple, unanalyzable, may be directly known by an intellect. Or, to be more explicit. Plurality, relation, difference, and likeness, are necessary conditions of intelligence through the Sense and Understanding; but they do not in the least degree lie upon the Reason, which sees its objects as pure, simple ideas which are _self-evident_, and, consequently, are not subject to those conditions. Whatever knowledge we may have of "mammals," we undoubtedly gain under the conditions of plurality, relation, difference, and likeness; for "mammals" are things in nature. But absoluteness is a pure, simple, unanalyzable idea in the Reason, and as such is seen and known by a direct insight as out of all plurality, relation, difference, and likeness: for this is a _quality_ of the self-existent Person, and so belongs wholly to the sphere of the supernatural, and can be examined only by a spiritual person who is also supernatural. Let us illustrate these two kinds of knowledge. 1. The knowledge given by the Sense and Understanding. This is of material objects. Take, for example, an apple. The Sense observes it as one of many apples, and that many characteristics belong to it as one apple. Among these, color, skin, pulp, juices, flavor, &c. may be mentioned. It observes, also, that it bears a relation to the stem and tree on which it grows, and, as well, that its several qualities have relations among themselves. One color belongs to the skin, another to the pulp. The skin, as cover, relates to the pulp as covered, and the like. The apple, moreover, is distinguished from other fruits by marks of difference and marks of likeness. It has a different skin, a different pulp, and a different flavor. Yet, it is like other fruits, in that it grows on a tree, and possesses those marks just named, which, though differing among themselves, according to the fruit in which they inhere, have a commonality of kind, as compared with other objects. This distinguishing, analyzing, and classifying of characteristics, and connecting them into a unity, as an apple, is the work of the Sense and Understanding.
