Imagination is likewise a faculty of the mind. If, by _imagination_, we understand the power of comparing images with ideas; of giving colours to our thoughts; of aggrandizing our sensations; of perceiving distinctly all the remote affinities of objects; it is the most brilliant and most active faculty of the mind of which brutes are still more destitute than of understanding or memory. But there is another kind of imagination which depends solely upon the corporeal organs, and which we possess in common with brutes; it is that tumultuous emotion, excited by objects analogous or contrary to our appetites; that lively and deep impression of the images of objects, which is constantly and against our inclinations, renewed, and forces us to act without reflection; this representation of objects, which is more active than even their presence, exaggerates and falsifies every thing. This imagination is forever hostile to the human mind; it is the source of illusion, the parent of these passions, which, in defiance of the efforts of reason, bear us away, and expose us to a continual combat, in which we are almost always worsted. _HOMO DUPLEX._ The interior man is double, being composed of two principles different in their nature, and contrary in their action. The soul, that principle of all knowledge, is perpetually opposed by another purely material principle. The former is a pure light, accompanied with serenity and peace, a salutary source, whence flow science, reason, and wisdom; the latter is a false light, which never shines but in the midst of darkness and hurricane, an impetuous torrent fraught with error and passion. The animal principle is first developed. As it is altogether material, and consists in the duration of vibrations, and the renovation of impressions formed in the internal material sense, by objects analogous, or contrary to our appetites, it begins to act as soon as the body is capable of feeling pain or pleasure. The spiritual principle manifests itself much later, and is developed and perfected by means of education; it is by the communication of the thoughts of others that the infant becomes a thinking, a rational being; and without this communication it would be fantastic or stupid, according to the degree of activity or inactivity of its internal material sense.
