INSTINCT AND REASON.
In the following paper we propose to discard entirely the word mind as an expression of the faculty of reflection, since it is frequently misapplied or misunderstood, and its employment is vague and unsatisfactory. We prefer using a term denoting the receptivity of ideas through an organic medium by an immaterial force having the power of acting on the ingestion of ideas, and diffusing its action through the corresponding media of the nervous system: this we shall call the intellectual force, and its action is the sequence of conscious or unconscious cerebration. It is not our purpose to enter upon a consideration of the higher relations of intellectual action with so-called spiritual forces, as this would necessarily tend to the contemplation of an extra element than that more particularly implied in the attributes of instinct and reason; for by these words, in their ordinary acceptation, we recognise two separate faculties, independent, yet coexistent, and capable of harmonious co-operation, but not necessarily co-ordinate nor coexistent, since the one we contend to be the natural property of all animated beings; while the other is in part the result of transmitted intelligence, education, and enlightenment, conveyed from a higher to a lower power.
Instinct, as the more universally diffused and common endowment, is to be found throughout the whole range of the animal kingdom; and to deny its existence in one class of creation and grant it in another is illogical and contrary to the recognised and established plan of creation; it is rather a general inheritance; in some forms of life the chief or sole guide to voluntary action; while in other or higher forms, partially overlaid, and in a measure superseded, by the faculty of reason. Yet we should be, we think, altogether wrong in supposing it non-existent, because, through the cultivation and development of reasoning power, it is less easily discerned, and less fully exercised in man, than in the lower animals; for, by inquiry in the lives of uncivilised humanity, we shall find undoubted proofs of instinct in the ordinary passages of savage life, as in the choice of food; the selection of certain herbs for medicinal purposes; the capacity of tracking a path from one point to another in great distances; the avoidance of poisonous articles of diet; casual injuries; and, above all, the clinging to life which is common to all mankind. And even in civilised beings, we may discern evident traces of the same property underlying the more ostensible gift of reason, and instinctive, though otherwise unaccountable, motives leading to definite conclusions. These may take the forms of likes or dislikes towards outer objects; impulses, frequently and truly termed unreasonable, because they arise apart from reason, and are purely instinctive; hence actions that are simply the outcomes of instinct, not reconcilable to the written laws of reason or the mandates of civilisation.
In some rare instances of humanity run wild, only a few of which have been recorded, where, by some accident, a human offspring has grown up as a denizen of the forest and the companion of wild beasts, the gift of instinct serves the same purpose it fulfils in the rest of the creation; and when first brought into contact with civilisation, these outcasts have apparently evinced few, or none, of the actual attributes of reason, though these have become perceptible later on through human companionship and attention. But even centuries of cultivation and the highest hereditary advantages fail utterly to eliminate or destroy the inherent property of instinct in man; for not only, as above stated, is it displayed in the common shrinking from death and the avoidance of injury and suffering, but it manifests itself in countless other instances in daily life. Let us regard the union of sexes as one: how frequently is the choice of a partner in life made through nothing less than a blind instinct, often apart from any reasoning process, so much so, that the fact has passed into a proverb that ‘Love is blind.’ And in the common affairs of life, it is often possible to trace an independent course of action pursued without reference to a reasoning faculty, rather by a blind adherence to an unseen hidden principle, which is undoubtedly instinct guiding rather than reason. And this obedience to an unknown faculty has doubtless, in the history of the world, played important parts; especially when, in prehistoric times, man was essentially a predatory animal. On his instinctive love of fighting for personal aggrandisement, and his instinctive love of the chase for providing food and clothing, his very existence in a great measure depended. Indeed, the motives which influence and direct men’s lives are only, after all, the attributes of instinct, as we commonly observe portrayed in civilised society; thus, in one, the instinct of commercial enterprise pushes towards speculation; in another, the instinct of self-preservation induces precautions of benefit to the community; again, the instinct of need prompts measures for procuring supplies of food and clothing. On all hands, human instinct is an active agent and irrepressible.
And further, we may find the instinct of an unseen yet overruling power dominant in one form or another among the whole human race; even where, degraded by numberless superstitions, it exists among the dusky tribes of Africa, the Red American Indians, or in the countless mythological legends of nations long passed away, the instinctive belief in a God holds universal sway. In the common affairs of life, too, the teaching of instinct is displayed, as in presentiments, which, like impulses, have frequently no rational basis, but by the observance of which, our lives are not uncommonly modified in their effects and made subservient to the unseen. It is indeed possible, were the chapters of human lives actually recorded, it would be found in how many important instances and numberless occasions the exercise of instinct prevails above that of reason. It is, however, to be noted, that in proportion as the exercise of intellectual force is stimulated by education and strengthened by practice, instinctive action becomes more and more influenced by reason; and just as particular muscles, by long use, increase in bulk, so the repeated receptivity of ideas by the higher organism of the brain leads to the reflective powers being increased; and, as a natural consequence, the actions thus performed betoken the connection of ideas from which they spring, and are consequently attributed to reason.
Reason may thus be regarded, in the abstract, as the result of ideas received by the sensory ganglia, and transmitted by them to the higher organs of perception, reflected thence on the motory system by which the actions of animal life are governed, the repeated discharge of these functions constituting processes of thought or reflection.
Admitting this to be a rough outline of reasoning with its outcome action, we have a familiar example of this process displayed by members of the animal kingdom that are habitually brought into the society and companionship of man. Daily usage supplies experience, which, by the receptivity of ideas, constitutes a reasoning faculty, such as is constantly manifested in the actions of various animals, and which as much overrules mere instinct in them as it does in the higher animal man. For example, in my dog the predatory instinct is very strongly marked; but it daily passes and frequently enters butchers’ shops, sniffing under the carcases and joints for any scraps of meat, however small, yet never attempting to take advantage of a piece that is offered for sale. We have also frequently noticed, when driving on our rounds in a country practice, the horse would voluntarily slacken its speed as it approached the house of a patient, and scarcely require a check to draw up at the door. Why some human beings should betray a jealous disapproval of the recognition of reason in animals, seems to us utterly unaccountable. It is surely no insult to the Creator of all things if we grant the attribute of reasoning powers to His creatures; while it savours strongly of narrow and limited views of His beneficence to deny it.
It is the object of this paper to claim recognition and respect for the reasoning faculties of animals, particularly the class of domestic animals that are brought into daily intercourse with man. In them, more especially, we note habits of thought and traits of intelligence, apart from and above the mere prompting of instinct, that entitle them to our best consideration. But in the dog, as the friend of man, we shall naturally find the examples most ready to hand, not only of emotions akin to those of his master, but sentiments of honour, love, watchfulness, trust, duty, and obedience, courage, forbearance, self-denial, overcoming the mere instinct of hunger; also sensitiveness, shame, and jealousy, with self-devotion surpassing even the fear of death. In the horse, too, we find obedience, trust, eagerness to please, and affection. Even in cattle, we may notice attachment to home and persons, courage, patience, and docility.
We do not here propose to enter on a list of the attributes of reason to be observed in all animals; it is needless to relate the numberless authenticated instances recorded of elephants, tamed deer, gazelles, monkeys, and birds. To the thoughtful observer, proofs of intelligence and reflection, with experience, judgment, and conscientiousness are readily found, and even in the wild animals, as the rat, the fox, lions, and tigers, remarkable facts are recorded, which evidence powers of reflection and the exercise of judgment and reason. A lion, for instance, has been seen to drive away a cow from the herd, not rending it at once, but urging it by menaces, so as to secure its prey in a more convenient spot. Tigers watch in the jungle for the passing post-carriers, recognising their approach by the jingling sound of their ornaments, and knowing from experience that the wearers will afford them the necessary meal. The stories of foxes are legion; their cunning in eluding pursuit, and their prompt recognition of such chance advantages as the occasion may afford, evince a reasoning power beyond the mere impulse of instinct. Again, in rats, who has not witnessed countless proofs of intelligence, denoting forethought, prudence, and care, not only in their search for food, avoidance of snares, and concealment, but also exemplified in their mutual intercourse? A regimental officer once stationed at Aden described to the writer the skill of a party of rats in purloining every day the bread placed on the dinner-table. The servant who laid the table could not account for the disappearance of the several portions of bread placed ready beside the napkin and glasses, till, after watching some time, a small party of rats was seen to enter the room, and while some of them held the lower border of the table-cloth, another rapidly ascended, and mounting the table, dislodged the pieces of bread, which, falling off, were speedily appropriated by those below. The beaver has been often cited as exhibiting an almost human aptitude in the construction of dams and the formation of its lodge, and this appears more as the result of deductive reasoning, taught, no doubt, by experience, and transmitted by hereditary descent. In birds, the Corvidæ afford striking instances of the exercise of judgment and reflection, especially in the habits of rooks and ravens; we might add also magpies. But space prevents us from enlarging on this point.
The common wild bee constructs its nest in a mossy bank, and the comb is formed of rude circular cells arranged in a small group. The hive-bee, whose thickly peopled home affords but a limited space, constructs its comb of closely packed hexagonal cells, an arrangement which gives the greatest room for each cell in a circumscribed area. It accidentally occurred to the writer, many years since, to put aside a large box of pills closely packed, and left, without being opened, through the summer. When at last examined, it was found that the pills had become closely impacted together, and each individual pill was compressed in the form of a hexagon, remarkably resembling in outline the waxen cells of the hive-bee. The conduct of ants, in their communications by signalling to each other, evinces something more than blind instinct; otherwise, how can we explain the deliberate action which results from information conveyed by signals, and the plan of operations conducted on a scale beyond all relation to the size of the insignificant insects by which they are performed?
Mankind is too apt to monopolise the claim to reason, and allows to the lower animal world the gift of instinct as a kind of compromise; whereas, it has been abundantly shown that he shares also in the gift of instinct, and they likewise have a fair claim to the exercise of reason. There is nothing inconsistent in this view with the great plan of creation, for all classes of animals partake of the elements of the human frame in their general physical construction adapted to particular requirements, as anatomists have shown that man in his development from the ovum passes through the several grades of the animal kingdom by different homologies to the perfect human frame. And though in him reason assumes its highest condition, yet in the various types of his race there are as widely differing degrees of reasoning power, from the tree-dwelling tribes of Central India and the Lilliputian inhabitants of the forests of Borneo, to the highly educated and more amply endowed members of European and transatlantic society; and as, in the human race, reason exercises a paramount and prevailing sway, under which all other forces are subject, so instinct remains behind, still an element of humanity, though less conspicuous in the higher culture of civilisation than in the primitive savage, and more evident still in the lower animal world; though even here subjected to reasoning power, according, in a manner, to the amount of education and enlightenment received by these at the hand of man. Instinct belongs no more to the brute beast than to man, and reason is the heritage of both.
