Animal or Natural Ethics
The existence of morality presupposes the existence of commandments of duty, and of an authority. Among animals, as well as among human beings, we find recognized authority and can discern the principles of action which constitute the duty of any particular animal. Authority among the lower animals is based on might, which is, indeed, the universal source of authority, without which no authority can exist. Personal authority is but a particular form of the authority of circumstances; and to this authority every creature must be subject. It consists of two factors: the outer authority of the environment, and the inner authority of impulse. Duty is obedience to authority. The duty of the organism consists in action that corresponds to these two authorities, following the direction given as the resultant of the mixture of the two components. That is, that manner of life is right or moral which renders the life of the organism the fullest possible under the circumstances. The unreasoning organism is unconsciously drawn to seek this maximum, while the reasoning being seeks it through reflection. The impulse to happiness includes, therefore, for the reasoning being, the impulse to morality; or, ideally expressed, the relative morality equals the relative happiness; morality and happiness are the same thing.
An authority without the means of enforcing itself is a self-contradiction. The means by which nature makes its authority felt is organic excitation. In proportion to its strength, an excitation produces sensation, in case it is not too weak to make itself felt at all. Every excitation has a definite significance and may come from without or within. Pleasant excitations are always, primarily, the feeling of the stilling of pain, though there are pains, such as, for instance, that of a wound, the toothache, headache, an aching corn, which have no corresponding feeling of pleasure. Nor is pleasure the only offspring of pain, since pain may bring forth pain. Pleasure depends, in its character as pleasure as well as in its strength, on the feeling preceding it in the organism; that is, its quality is the result, not of the degree of organic excitation, but of the order of succession of the feelings. For this reason, the same feeling which brings pleasure to one individual may bring pain to another.
This whole deduction is at variance with Spencer's theory that pleasurable excitations are favorable to life, painful ones injurious. And since observation is in direct opposition to his assertion, his followers have been obliged to supplement it with the conception that pain is gradually weeded out by natural selection. On the contrary, we need pain at every instant, since it is the impulse to action; persistence in the same condition through lack of excitation, must result in death; pleasure can never originate action, it can only cause persistence in action already begun. The fact has been too often overlooked, that the motive and the "end" of an action are by no means the same. The motive is pain, and the end is either simply the stilling of pain or an additional positive pleasure. There are, therefore, many actions which are directed to no concrete positive end, but only to the purely negative end of escape from pain without consideration of the further results; a striking example of such action is suicide. Even where positive pleasure appears as an end, it is never in itself the motive to action. In order to become a motive, it must first be transformed into an excitation, into desire for pleasure; and this desire for a definite or an indefinite pleasure is, in its essence, pain—the pain of the absence of pleasure.[60]
The pleasure sought may be one already known through experience, or it may be one not yet experienced. In the latter case, the desire is awakened by instruction or reflection, or else induced by instinct. But the motive is always the same, namely, a seeking after pleasure, hence a feeling of pain.
This view furnishes us with a psychical explanation of the association of ideas, the mysterious so-called transferrence of the feeling of pleasure from the end to the means. Pleasure begins as soon as we have begun the action which will bring us with certainty to the end desired, and this pleasure may reach such a degree of strength at some point of the process as to conquer the desire for the real end, hem further action, and dispose to continuance at the point reached. The action of the miser may be thus explained.
The objection that, if pain is the motive, the organism is nothing but a bundle of pains, is by no means valid, for it overlooks the fact that pain remains, in an immense number of cases, below the threshold of consciousness; as in the case of organic action, where it is rhythmic. The same is true of reflex action. To any close observer of the lower organisms, it seems most probable that these possess consciousness (see Wundt, "Physiologische Psychologie"), nor is it by any means proved that the plants do not possess it likewise. It is certainly remarkable that exactly the lowest plants, which stand so near the animals in the phenomena of their life, exhibit movements closely resembling those of animals. And it is, moreover, a fact that automatic and reflex actions increase with the degree of organization, and are most numerous in human beings. With increased exercise, one chain of movements after the other is withdrawn from consciousness; and through this removal from consciousness action gains in certainty and rapidity, and in energy also, since the part of the force which was before lost in inducing consciousness is now released. Such removal from consciousness is, therefore, a benefit to the organism, as an adaptation to the increased demands of circumstances. Movements which thus become unconscious are each and every one of them movements which have but one definite end and an interruption of which either kills or seriously injures the organism, or at least brings disorder into its life for the time being. An easily excited consciousness would be an exceeding danger to the animal. Conscious action is directed to the attainment of variable ends by means which are also variable. It cannot, therefore, astonish us that consciousness disappeared in plants after the loss of free motion.
By the regular exercise of certain actions or of trains of thought, either through necessity or by habit certain tracks are worn or taken possession of, so that the whole process, from the excitation to the action resulting upon it, takes place with such rapidity that we are no longer conscious of its separate phases and so of the growth of the result.
