Kant saw the mass of empirical and hence irrelevant detail that had found refuge within this liberal and diffusive reason. He saw that the idea of reason could be made self-consistent only by stripping it naked of these empirical accretions. He then provided, in his critiques, a somewhat cumbrous moving van for transferring the resultant pure or naked reason out of nature and the objective world, and for locating it in new quarters, with a new stock of goods and new customers. The new quarters were particular subjects, individuals; the stock of goods were the forms of perception and the functions of thought by which empirical flux is woven into durable fabrics; the new customers were a society of individuals in which all are ends in themselves. There ought to be an injunction issued that Kant’s saying about Hume’s awakening of him should not be quoted save in connection with his other saying that Rousseau brought him to himself, in teaching him that the philosopher is of less account than the laborer in the fields unless he contributes to human freedom. But none the less, the new tenant, the universal reason, and the old homestead, the empirical tumultuous individual, could not get on together. Reason became a mere voice which, having nothing in particular to say, said Law, Duty, in general, leaving to the existing social order of the Prussia of Frederick the Great the congenial task of declaring just what was obligatory in the concrete. The marriage of freedom and authority was thus celebrated with the understanding that sentimental primacy went to the former and practical control to the latter.
The effort to force a universal reason that had been used to the broad domains of the cosmos into the cramped confines of individuality conceived as merely “empirical,” a highly particularized creature of sense, could have but one result: an explosion. The products of that explosion constitute the Post-Kantian philosophies. It was the work of Hegel to attempt to fill in the empty reason of Kant with the concrete contents of history. The voice sounded like the voice of Aristotle, Thomas of Aquino, and Spinoza translated into Swabian German; but the hands were as the hands of Montesquieu, Herder, Condorcet, and the rising historical school. The outcome was the assertion that history is reason, and reason is history: the actual is rational, the rational is the actual. It gave the pleasant appearance (which Hegel did not strenuously discourage) of being specifically an idealization of the Prussian nation, and incidentally a systematized apologetic for the universe at large. But in intellectual and practical effect, it lifted the idea of process above that of fixed origins and fixed ends, and presented the social and moral order, as well as the intellectual, as a scene of becoming, and it located reason somewhere within the struggles of life.
Unstable equilibrium, rapid fermentation, and a succession of explosive reports are thus the chief notes of modern ethics. Scepticism and traditionalism, empiricism and rationalism, crude naturalisms and all-embracing idealisms, flourish side by side—all the more flourish, one suspects, because side by side. Spencer exults because natural science reveals that a rapid transit system of evolution is carrying us automatically to the goal of perfect man in perfect society; and his English idealistic contemporary, Green, is so disturbed by the removal from nature of its moral qualities, that he tries to show that this makes no difference, since nature in any case is constituted and known through a spiritual principle which is as permanent as nature is changing. An Amiel genteelly laments the decadence of the inner life, while his neighbor Nietzsche brandishes in rude ecstasy the banner of brute survival as a happy omen of the final victory of nobility of mind. The reasonable conclusion from such a scene is that there is taking place a transformation of attitude towards moral theory rather than mere propagation of varieties among theories. The classic theories all agreed in one regard. They all alike assumed the existence of the end, the summum bonum, the final goal; and of the separate moral force that moves to that goal. Moralists have disputed as to whether the end is an aggregate of pleasurable state of consciousness, enjoyment of the divine essence, acknowledgment of the law of duty, or conformity to environment. So they have disputed as to the path by which the final goal is to be reached: fear or benevolence? reverence for pure law or pity for others? self-love or altruism? But these very controversies implied that there was but the one end and the one means.
The transformation in attitude, to which I referred, is the growing belief that the proper business of intelligence is discrimination of multiple and present goods and of the varied immediate means of their realization; not search for the one remote aim. The progress of biology has accustomed our minds to the notion that intelligence is not an outside power presiding supremely but statically over the desires and efforts of man, but is a method of adjustment of capacities and conditions within specific situations. History, as the lecturer on that subject told us, has discovered itself in the idea of process. The genetic standpoint makes us aware that the systems of the past are neither fraudulent impostures nor absolute revelations; but are the products of political, economic, and scientific conditions whose change carries with it change of theoretical formulations. The recognition that intelligence is properly an organ of adjustment in difficult situations makes us aware that past theories were of value so far as they helped carry to an issue the social perplexities from which they emerged. But the chief impact of the evolutionary method is upon the present. Theory having learned what it cannot do, is made responsible for the better performance of what needs to be done, and what only a broadly equipped intelligence can undertake: study of the conditions out of which come the obstacles and the resources of adequate life, and developing and testing the ideas that, as working hypotheses, may be used to diminish the causes of evil and to buttress and expand the sources of good. This program is indeed vague, but only unfamiliarity with it could lead one to the conclusion that it is less vague than the idea that there is a single moral ideal and a single moral motive force.
From this point of view there is no separate body of moral rules; no separate system of motive powers; no separate subject-matter of moral knowledge, and hence no such thing as an isolated ethical science. If the business of morals is not to speculate upon man’s final end and upon an ultimate standard of right, it is to utilize physiology, anthropology, and psychology to discover all that can be discovered of man, his organic powers and propensities. If its business is not to search for the one separate moral motive, it is to converge all the instrumentalities of the social arts, of law, education, economics, and political science upon the construction of intelligent methods of improving the common lot.
If we still wish to make our peace with the past, and to sum up the plural and changing goods of life in a single word, doubtless the term happiness is the one most apt. But we should again exchange free morals for sterile metaphysics, if we imagine that “happiness” is any less unique than the individuals who experience it; any less complex than the constitution of their capacities, or any less variable than the objects upon which their capacities are directed.
To many timid, albeit sincere, souls of an earlier century, the decay of the doctrine that all true and worthful science is knowledge of final causes seemed fraught with danger to science and to morals. The rival conception of a wide open universe, a universe without bounds in time or space, without final limits of origin or destiny, a universe with the lid off, was a menace. We now face in moral science a similar crisis and like opportunity, as well as share in a like dreadful suspense. The abolition of a fixed and final goal and causal force in nature did not, as matter of fact, render rational conviction less important or less attainable. It was accompanied by the provision of a technique of persistent and detailed inquiry in all special fields of fact, a technique which led to the detection of unsuspected forces and the revelation of undreamed of uses. In like fashion we may anticipate that the abolition of the final goal and the single motive power and the separate and infallible faculty in morals, will quicken inquiry into the diversity of specific goods of experience, fix attention upon their conditions, and bring to light values now dim and obscure. The change may relieve men from responsibility for what they cannot do, but it will promote thoughtful consideration of what they may do and the definition of responsibility for what they do amiss because of failure to think straight and carefully. Absolute goods will fall into the background, but the question of making more sure and extensive the share of all men in natural and social goods will be urgent, a problem not to be escaped nor evaded.
Morals, philosophy, returns to its first love; love of the wisdom that is nurse, as nature is mother, of good. But it returns to the Socratic principle equipped with a multitude of special methods of inquiry and testing; with an organized mass of knowledge, and with control of the arrangements by which industry, law, and education may concentrate upon the problem of the participation by all men and women, up to their capacity of absorption, in all attained values. Morals may then well leave to poetry and to art, the task (so unartistically performed by philosophy since Plato) of gathering together and rounding out, into one abiding picture, the separate and special goods of life. It may leave this task with the assurance that the resultant synthesis will not depict any final and all-inclusive good, but will add just one more specific good to the enjoyable excellencies of life.
Humorous irony shines through most of the harsh glances turned towards the idea of an experimental basis and career for morals. Some shiver in the fear that morals will be plunged into anarchic confusion—a view well expressed by a recent writer in the saying that if the a priori and transcendental basis of morals be abandoned “we shall have merely the same certainty that now exists in physics and chemistry”! Elsewhere lurks the apprehension that the progress of scientific method will deliver the purposive freedom of man bound hand and foot to the fatal decrees of iron necessity, called natural law. The notion that laws govern and forces rule is an animistic survival. It is a product of reading nature in terms of politics in order to turn around and then read politics in the light of supposed sanctions of nature. This idea passed from medieval theology into the science of Newton, to whom the universe was the dominion of a sovereign whose laws were the laws of nature. From Newton it passed into the deism of the eighteenth century, whence it migrated into the philosophy of the Enlightenment, to make its last stand in Spencer’s philosophy of the fixed environment and the static goal.
No, nature is not an unchangeable order, unwinding itself majestically from the reel of law under the control of deified forces. It is an indefinite congeries of changes. Laws are not governmental regulations which limit change, but are convenient formulations of selected portions of change followed through a longer or shorter period of time, and then registered in statistical forms that are amenable to mathematical manipulation. That this device of shorthand symbolization presages the subjection of man’s intelligent effort to fixity of law and environment is interesting as a culture survival, but is not important for moral theory. Savage and child delight in creating bogeys from which, their origin and structure being conveniently concealed, interesting thrills and shudders may be had. Civilized man in the nineteenth century outdid these bugaboos in his image of a fixed universe hung on a cast-iron framework of fixed, necessary, and universal laws. Knowledge of nature does not mean subjection to predestination, but insight into courses of change; an insight which is formulated in “laws,” that is, methods of subsequent procedure.
