the organs or faculties of affection and thought; the terms affection and thought refer to the activities of those organisms or their outward functions, while the terms love and wisdom refer to their interior essence. Affection rules over thought. It gives thought its character and quality. If the affections are for science, the thoughts are scientific. If they are for literature, the thoughts are literary. If the affections are debased, the thoughts will be; if pure, the thoughts will correspond. Such is the relation between affection and thought that thought may be correctly defined as the manner in which affections act. Thought is nothing other than the form in which affections act. Then since thought is affection's action, the life of the brain may be reduced to one primal element, that of affection or love. From a higher standpoint, therefore, love, or affection, is the life of the brain, while thought is its form of manifestation in the understanding. Having observed that affection and thought are properties of a high substance, we may name that substance itself love. Operating in the will it produces affection; operating in the understanding, it produces thought, and thence the activities of the brain particles, and all the mental operations in their great variety.
