4404. Each of the five external senses - touch, taste, smell, hearing, and sight - has a correspondence with one of the internal senses. But today correspondences are known to scarcely anyone because people are not even aware of the existence of correspondences, let alone of the correspondence of spiritual things with natural ones, or what amounts to the same, of things belonging to the internal man with those belonging to the external. As regards the correspondences of the senses, the sense of touch in general corresponds to the affection for good; the sense of taste to the affection for knowing; the sense of smell to the affection for perceiving; the sense of hearing to the affection for learning, and also to obedience; while the sense of sight corresponds to the affection for being intelligent and wise.
