The three kinds of soul, vegetative, animal and rational, we have already met before. We have also referred to the fact that Judah Halevi analyzes correctly the well-known Aristotelian definition of the soul. We must now give a brief account of the inner senses as Judah Halevi took it from Avicenna. The five external senses, seeing, hearing, touching, smelling and tasting, give us merely colors, sounds, touch sensations, odors and tastes. These are combined into an object by the _common sense_, known also as the _forming power_. Thus when we see honey we associate with its yellow color a sweet taste. This could not be done unless we had a power which combines in it all the five senses. For the sense of sight cannot perceive taste, nor can color be apprehended by the gustatory sense. There is need therefore of a common sense which comprehends all the five external senses. This is the first internal sense. This retains the forms of sensible objects just as the external senses present them. Then comes the _composing power_ or power of imagination. This composes and divides the material of the common sense. It may be true or false, whereas the common sense is always true. Both of these give us merely forms; they do not exercise any judgment. The latter function belongs to the third internal sense, the _power of judgment_. Through this an animal is enabled to decide that a given object is to be sought or avoided. It also serves to rectify the errors of reproduction that may be found in the preceding faculty of imagination. Love, injury, belief, denial, belong likewise to the judging faculty together with such judgments as that the wolf is an enemy, the child a friend. The last of the internal senses is that of _factual memory_, the power which retains the judgments made by the faculty preceding. In addition to these sensory powers the animal possesses motor faculties. These are two, the _power of desire_, which moves the animal to seek the agreeable; and the _power of anger_, which causes it to reject or avoid the disagreeable. All these powers are dependent upon the corporeal organs and disappear with the destruction of the latter.
