_Judgment_ is that faculty of the Mind whereby we determine the agreement or disagreement between two concepts, ideas, or objects of thought, by comparing them with each other. From this comparison arises the judgment, which is expressed in the shape of a logical _proposition_: "The horse is an animal;" or "the horse is not a cow." Judgment is also used in forming a concept, in the first place, for we must _compare qualities_ before we can form a _general idea_. _Reasoning_ is that faculty of the Mind whereby we compare two Judgments, one with the other, and from the comparison deduce a third Judgment. This is a form of indirect or mediate comparison, whereas the Judgment is a form of immediate or direct comparison. From this process of Reasoning arises a result which is expressed in what is called a Syllogism, as for instance: "All dogs are animals; Carlo is a dog; therefore, Carlo is an animal." Or expressed in symbols: "A equals C; and B equals C;" therefore, "A equals B." Reasoning is of two kinds or classes; _viz._, Inductive and Deductive, respectively. We have explained these forms of Reasoning in detail in another volume of this series. _The Feelings_ are the mental faculties whereby we experience emotions or feelings. Feelings are the experiencing of the agreeable or disagreeable nature of our mental states. They can be defined only in their own terms. If we have never experienced a feeling, we cannot understand the words expressing it. Feelings result in what are called emotion, affection and desire. An emotion is the simple feeling, such as joy, sorrow, etc. An affection is an emotion reaching out toward another and outside object, such as envy, jealousy, love, etc. A desire is an emotion arising from the _want_ of some lacking quality or thing, and the inclination to possess it. _Memory_ is the faculty of the Mind whereby we retain and reproduce, or consciously revive any kind of past mental experience. It has two sub-phases; _viz._, Retention and Recollection, respectively. It manifests in the storing away of mental images and ideas, and in the reproduction of them at a later period of time, and also of the recognition of them as objects of past experience. _Imagination_ is the faculty of the Mind whereby we represent (_re-pre-sent_) as a mental image some previously experienced idea, concept or image. Its activities are closely allied and blended with those of the Memory. It has the power not only of reproducing objects already perceived but also another power of _ideal creation_ whereby it _creates_ new combinations from the materials of past experience. It is a faculty, the importance of which is but little understood by the majority of men. Inasmuch as the mental image must always precede the material manifestation, the cultivation of the Imagination becomes a matter of great importance and worthy of the closest study.
