22. The instincts also belong to the connate mechanism, and in the course of the normal experience of the animal inevitably come into play; but, unlike the automatic tendencies of breathing, swallowing, and coughing, they are capable of modification, or even suppression, by alterations in the course of individual experience. The connate mechanism of the cat determines its dread of water, and its enmity to the dog and mouse; yet a cat will by the modifications of certain experiences become as ready as an otter to take to the water, and become so fond of a dog that she will allow him to tend upon her kittens; and so indifferent to the mouse that she will let it run over her body. All this implies a new adjustment in the nervous centres, with new modes of reaction on sensory impressions: the inherited mechanism has been modified. I need not dwell on the profound modifications which the human inherited mechanism undergoes in the course of experience--how social influences and moral and religious teachings redirect, or even suppress, many primary tendencies; so that “moral habits” become organized, and replace the original tendencies of the organism. These, when organized, become the inevitable modes of reaction, and are sometimes called secondarily automatic. It is important to recognize this organization of experiences, this acquisition of a secondary or modified constitution, if we would explain psychological processes by physiological processes. Thus the processes of Logic are automatic, they belong to the connate primary mechanism, and their action is inevitable, invariable. The elements of a judgment, like the elements of a perception, may vary, and we therefore say that one judgment is false, and one perception incomplete; but the judging process is always the same, and the perceiving process is always the same. We may breathe pure air or impure air, but the breathing process is in each case the same; and judgment is as automatic as breathing, not to be altered, not to be suppressed. Again, the moral terror at wickedness of any recognized kind is as automatic as the instinctive terror at danger. The one has its roots in the primary disposition called love of approbation and its correlative dread of disapprobation: the social instinct. The other has its root in the primary disposition called “instinct of self-preservation,” which is really the reflex shrinking from pain: the physiological instinct.
