SENSES. Referring for an account of the several Senses to their respective designa tions, we will here endeavor to state what faculties or sensibilities of the mind are prop erly included under the name.
The common reckoning includes the five senses—taste, smell, touch, hearing, sight— but this is not now considered exhaustive,or complete.
For example, the feelings of hunger, thirst, suffocation, internal warmth and chill ness, etc., have all the characters implied in an ordinary sensation; they are the result of some external agent acting on a distinct bodily organ. and giving rise to feeting, some times pleasurable and sometimes painful. In Order that these states, related to the sensibility of the different viscera, may find a place among the senses. they have been grouped under one general head, and designated "sensations of organic life." They are of great importance as regards our enjoyments and our sufferings. although not con tributing much to our knowledge or intelligence. They approach nearest to taste and Smell, the more emotional senses, and are at the furthest remove from the intellectual senses—touch, hearing. and sight.
Again, the feelings connected with our activity, or wills the exercise of the muscular organs—as the pleasures of exercise and rest. the pains of fatigue, the sensibility to
weight, resistance, etc.—were, until lately, overlooked in the philosophy of the mind. When they began to be recognized it was common to treat them as a sixth sense, called the muscular sense But this does not represent their true position. They do not arise front external agents on a sensitive part, but from internal impulses proceed ing outward to stimulate the muscular energies, and to bring about movements; they are thus tho contrast of the senses generally. Sense is associated with the in-going nerve currents, movement with the out-going, The contrast is vital and fundamental; and accordingly the feeling's of movement and muscular strain should he considered as a genus distinct from the germs sense, and not as a species of that genus.
The classification of the fundamental sensibilities of the mind would then stand thus: I. Feelings of umseulur energ.y. II. Sensations, of the senses: 1. Organic RN; 2. Taste; 3. Smell—emotional; 4. Touch; 5. Hearing; 3. Sight—intelleetual.
