The Data of Ethics. Spencer Herbert
waterfall, shall I go over the moor or take the path through the wood? Here the means are ethically indifferent. And from hour to hour most of the things we do are not to be judged as either good or bad in respect of either ends or means.
No less clear is it that the transition from indifferent acts to acts which are good or bad is gradual. If a friend who is with me has explored the sea-shore, but has not seen the waterfall, the choice of one or other end is no longer ethically indifferent. And if, the waterfall being fixed on as our goal, the way over the moor is too long for his strength, while the shorter way through the wood is not, the choice of means is no longer ethically indifferent. Again, if a probable result of making the one excursion rather than the other, is that I shall not be back in time to keep an appointment, or if taking the longer route entails this risk while taking the shorter does not, the decision in favor of one or other end or means acquires in another way an ethical character; and if the appointment is one of some importance, or one of great importance, or one of life-and-death importance, to self or others, the ethical character becomes pronounced. These instances will sufficiently suggest the truth that conduct with which Morality is not concerned, passes into conduct which is moral or immoral, by small degrees and in countless ways.
But the conduct that has to be conceived scientifically before we can scientifically conceive those modes of conduct which are the objects of ethical judgments, is a conduct immensely wider in range than that just indicated. Complete comprehension of conduct is not to be obtained by contemplating the conduct of human beings only; we have to regard this as a part of universal conduct—conduct as exhibited by all living creatures. For evidently this comes within our definition—acts adjusted to ends. The conduct of the higher animals as compared with that of man, and the conduct of the lower animals as compared with that of the higher, mainly differ in this, that the adjustments of acts to ends are relatively simple and relatively incomplete. And as in other cases, so in this case, we must interpret the more developed by the less developed. Just as, fully to understand the part of conduct which Ethics deals with, we must study human conduct as a whole; so, fully to understand human conduct as a whole, we must study it as a part of that larger whole constituted by the conduct of animate beings in general.
Nor is even this whole conceived with the needful fullness, so long as we think only of the conduct at present displayed around us. We have to include in our conception the less-developed conduct out of which this has arisen in course of time. We have to regard the conduct now shown us by creatures of all orders, as an outcome of the conduct which has brought life of every kind to its present height. And this is tantamount to saying that our preparatory step must be to study the evolution of conduct.
CHAPTER II.
THE EVOLUTION OF CONDUCT.
§ 3. We have become quite familiar with the idea of an evolution of structures throughout the ascending types of animals. To a considerable degree we have become familiar with the thought that an evolution of functions has gone on pari passu with the evolution of structures. Now, advancing a step, we have to frame a conception of the evolution of conduct, as correlated with this evolution of structures and functions.
These three subjects are to be definitely distinguished. Obviously the facts comparative morphology sets forth, form a whole which, though it cannot be treated in general or in detail without taking into account facts belonging to comparative physiology, is essentially independent. No less clear is it that we may devote our attention exclusively to that progressive differentiation of functions, and combination of functions, which accompanies the development of structures—may say no more about the characters and connections of organs than is implied in describing their separate and joint actions. And the subject of conduct lies outside the subject of functions, if not as far as this lies outside the subject of structures, still, far enough to make it substantially separate. For those functions which are already variously compounded to achieve what we regard as single bodily acts, are endlessly recompounded to achieve that co-ordination of bodily acts which is known as conduct.
We are concerned with functions in the true sense, while we think of them as processes carried on within the body; and, without exceeding the limits of physiology, we may treat of their adjusted combinations, so long as these are regarded as parts of the vital consensus. If we observe how the lungs aërate the blood which the heart sends to them; how heart and lungs together supply aërated blood to the stomach, and so enable it to do its work; how these co-operate with sundry secreting and excreting glands to further digestion and to remove waste matter; and how all of them join to keep the brain in a fit condition for carrying on those actions which indirectly conduce to maintenance of the life at large; we are dealing with functions. Even when considering how parts that act directly on the environment—legs, arms, wings—perform their duties, we are still concerned with functions in that aspect of them constituting physiology, so long as we restrict our attention to internal processes, and to internal combinations of them.
But we enter on the subject of conduct when we begin to study such combinations among the actions of sensory and motor organs as are externally manifested. Suppose that instead of observing those contractions of muscles by which the optic axes are converged and the foci of the eyes adjusted (which is a portion of physiology), and that instead of observing the co-operation of other nerves, muscles and bones, by which a hand is moved to a particular place and the fingers closed (which is also a portion of physiology), we observe a weapon being seized by a hand under guidance of the eyes. We now pass from the thought of combined internal functions to the thought of combined external motions. Doubtless, if we could trace the cerebral processes which accompany these, we should find an inner physiological co-ordination corresponding with the outer co-ordination of actions. But this admission is consistent with the assertion, that when we ignore the internal combination and attend only to the external combination, we pass from a portion of physiology to a portion of conduct. For though it may be objected that the external combination instanced is too simple to be rightly included under the name conduct, yet a moment's thought shows that it is joined with what we call conduct by insensible gradations. Suppose the weapon seized is used to ward off a blow. Suppose a counter-blow is given. Suppose the aggressor runs and is chased. Suppose there comes a struggle and a handing him over to the police. Suppose there follow the many and varied acts constituting a prosecution. Obviously the initial adjustment of an act to an end, inseparable from the rest, must be included with them under the same general head; and obviously from this initial simple adjustment, having intrinsically no moral character, we pass by degrees to the most complex adjustments and to those on which moral judgments are passed.
Hence, excluding all internal co-ordinations, our subject here is the aggregate of all external co-ordinations; and this aggregate includes not only the simplest as well as the most complex performed by human beings, but also those performed by all inferior beings considered as less or more evolved.
§ 4. Already the question: What constitutes advance in the evolution of conduct, as we trace it up from the lowest types of living creatures to the highest? has been answered by implication. A few examples will now bring the answer into conspicuous relief.
We saw that conduct is distinguished from the totality of actions by excluding purposeless actions; but during evolution this distinction arises by degrees. In the very lowest creatures most of the movements from moment to moment made, have not more recognizable aims than have the struggles of an epileptic. An infusorium swims randomly about, determined in its course not by a perceived object to be pursued or escaped, but, apparently, by varying stimuli in its medium; and its acts, unadjusted in any appreciable way to ends, lead it now into contact with some nutritive substance which it absorbs, and now into the neighborhood of some creature by which it is swallowed and digested. Lacking those developed senses and motor powers which higher animals possess, ninety-nine in the hundred of these minute animals, severally living for but a few hours, disappear either by innutrition or by destruction. The conduct is constituted of actions so little adjusted to ends, that life continues only as long as the accidents of the environment are favorable. But when, among aquatic creatures, we observe one which, though still low in type, is
