It is the testimony of his friends as well as of his writings that the theoretical position of Marx, both as regards his standpoint and as regards his main tenets, fell into a definitive shape relatively early, and that his later work was substantially a working out of what was contained in the position taken at the outset of his career.[3] By the latter half of the forties, if not by the middle of the forties, Marx and Engels had found the outlook on human life which came to serve as the point of departure and the guide for their subsequent development of theory. Such is the view of the matter expressed by Engels during the later years of his life.[4] The position taken by the two great leaders, and held by them substantially intact, was a variant of neo-Hegelianism, as has been indicated in an earlier section of this paper.[5] But neo-Hegelianism was short-lived, particularly considered as a standpoint for scientific theory. The whole romantic school of thought, comprising neo-Hegelianism with the rest, began to go to pieces very soon after it had reached an approach to maturity, and its disintegration proceeded with exceptional speed, so that the close of the third quarter of the century saw the virtual end of it as a vital factor in the development of human knowledge. In the realm of theory, primarily of course in the material sciences, the new era belongs not to romantic philosophy, but to the evolutionists of the school of Darwin. Some few great figures, of course, stood over from the earlier days, but it turns out in the sequel that they have served mainly to mark the rate and degree in which the method of scientific knowledge has left them behind. Such were Virchow and Max Müller, and such, in economic science, were the great figures of the Historical School, and such, in a degree, were also Marx and Engels. The later generation of socialists, the spokesmen and adherents of Marxism during the closing quarter of the century, belong to the new generation, and see the phenomena of human life under the new light. The materialistic conception in their handling of it takes on the color of the time in which they lived, even while they retain the phraseology of the generation that went before them.[6]

The difference between the romantic school of thought, to which Marx belonged, and the school of the evolutionists into whose hands the system has fallen,—or perhaps, better, is falling,—is great and pervading, though it may not show a staring superficial difference at any one point,—at least not yet. The discrepancy between the two is likely to appear more palpable and more sweeping when the new method of knowledge has been applied with fuller realisation of its reach and its requirement in that domain of knowledge that once belonged to the neo-Hegelian Marxism. The supplanting of the one by the other has been taking place slowly, gently, in large measure unavowedly, by a sort of precession of the point of view from which men size up the facts and reduce them to intelligible order.

The neo-Hegelian, romantic, Marxian standpoint was wholly personal, whereas the evolutionistic—it may be called Darwinian—standpoint is wholly impersonal. The continuity sought in the facts of observation and imputed to them by the earlier school of theory was a continuity of a personal kind,—a continuity of reason and consequently of logic. The facts were construed to take such a course as could be established by an appeal to reason between intelligent and fair-minded men. They were supposed to fall into a sequence of logical consistency. The romantic (Marxian) sequence of theory is essentially an intellectual sequence, and it is therefore of a teleological character. The logical trend of it can be argued out. That is to say, it tends to a goal. On the other hand, in the Darwinian scheme of thought, the continuity sought in and imputed to the facts is a continuity of cause and effect. It is a scheme of blindly cumulative causation, in which there is no trend, no final term, no consummation. The sequence is controlled by nothing but the vis a tergo of brute causation, and is essentially mechanical. The neo-Hegelian (Marxian) scheme of development is drawn in the image of the struggling ambitious human spirit: that of Darwinian evolution is of the nature of a mechanical process.[7]

What difference, now, does it make if the materialistic conception is translated from the romantic concepts of Marx into the mechanical concepts of Darwinism? It distorts every feature of the system in some degree, and throws a shadow of doubt on every conclusion that once seemed secure.[8] The first principle of the Marxian scheme is the concept covered by the term "Materialistic," to the effect that the exigencies of the material means of life control the conduct of men in society throughout, and thereby indefeasibly guide the growth of institutions and shape every shifting trait of human culture. This control of the life of society by the material exigencies takes effect through men's taking thought of material (economic) advantages and disadvantages, and choosing that which will yield the fuller material measure of life. When the materialistic conception passes under the Darwinian norm, of cumulative causation, it happens, first, that this initial principle itself is reduced to the rank of a habit of thought induced in the speculator who depends on its light, by the circumstances of his life, in the way of hereditary bent, occupation, tradition, education, climate, food supply, and the like. But under the Darwinian norm the question of whether and how far material exigencies control human conduct and cultural growth becomes a question of the share which these material exigencies have in shaping men's habits of thought, i.e., their ideals and aspirations, their sense of the true, the beautiful, and the good. Whether and how far these traits of human culture and the institutional structure built out of them are the outgrowth of material (economic) exigencies becomes a question of what kind and degree of efficiency belongs to the economic exigencies among the complex of circumstances that conduce to the formation of habits. It is no longer a question of whether material exigencies rationally should guide men's conduct, but whether, as a matter of brute causation, they do induce such habits of thought in men as the economic interpretation presumes, and whether in the last analysis economic exigencies alone are, directly or indirectly, effective in shaping human habits of thought.

Tentatively and by way of approximation some such formulation as that outlined in the last paragraph is apparently what Bernstein and others of the "revisionists" have been seeking in certain of their speculations,[9] and, sitting austere and sufficient on a dry shoal up stream, Kautsky has uncomprehendingly been addressing them advice and admonition which they do not understand.[10] The more intelligent and enterprising among the idealist wing—where intellectual enterprise is not a particularly obvious trait—have been struggling to speak for the view that the forces of the environment may effectually reach men's spiritual life through other avenues than the calculus of the main chance, and so may give rise to habitual ideals and aspirations independent of, and possibly alien to, that calculus.[11]

So, again, as to the doctrine of the class struggle. In the Marxian scheme of dialectical evolution the development which is in this way held to be controlled by the material exigencies must, it is held, proceed by the method of the class struggle. This class struggle is held to be inevitable, and is held inevitably to lead at each revolutionary epoch to a more efficient adjustment of human industry to human uses, because, when a large proportion of the community find themselves ill served by the current economic arrangements, they take thought, band together, and enforce a readjustment more equitable and more advantageous to them. So long as differences of economic advantage prevail, there will be a divergence of interests between those more advantageously placed and those less advantageously placed. The members of society will take sides as this line of cleavage indicated by their several economic interests may decide. Class solidarity will arise on the basis of this class interest, and a struggle between the two classes so marked off against each other will set in,—a struggle which, in the logic of the situation, can end only when the previously less fortunate class gains the ascendancy,—and so must the class struggle proceed until it shall have put an end to that diversity of economic interest on which the class struggle rests. All this is logically consistent and convincing, but it proceeds on the ground of reasoned conduct, calculus of advantage, not on the ground of cause and effect. The class struggle so conceived should always and everywhere tend unremittingly toward the socialistic consummation, and should reach that consummation in the end, whatever obstructions or diversions might retard the sequence of development along the way. Such is the notion of it embodied in the system of Marx. Such, however, is not the showing of history. Not all nations or civilisations have advanced unremittingly toward a socialistic consummation, in which all divergence of economic interest has lapsed or would lapse. Those nations and civilisations which have decayed and failed, as nearly all known nations and civilisations have done, illustrate the point that, however reasonable and logical the advance by means of the class struggle may be, it is by no means inevitable. Under the Darwinian norm it must be held that men's reasoning is largely controlled by other than logical, intellectual forces; that the conclusion reached by public or class opinion is as much, or more, a matter of sentiment than of logical inference; and that the sentiment which animates men, singly or collectively, is as much, or more, an outcome of habit and native propensity as of calculated material interest. There is, for instance, no warrant in the Darwinian scheme of things for asserting a priori that the class interest of the working class will bring them to take a stand against the propertied class. It may as well be that their training in subservience to their employers will bring them again to realise the equity and excellence of the established system of subjection and unequal distribution of wealth. Again, no one, for instance, can tell to-day what will be the outcome of the present situation in Europe and America. It may be that the working classes will go forward along the line of the socialistic ideals and enforce a new deal, in which there shall be no economic class discrepancies, no international animosity, no dynastic politics. But then it may also, so far as can be foreseen, equally well happen that the working class, with the rest of the community in Germany, England, or America, will be led by the habit of loyalty and by their sportsmanlike propensities to lend themselves enthusiastically to the game of dynastic politics, which alone their sportsmanlike rulers consider worth while. It is quite impossible on Darwinian ground to foretell whether the "proletariat" will go on to establish the socialistic revolution or turn aside again, and sink their force in the broad sands of patriotism. It is a question of habit and native propensity and of the range of stimuli to which the proletariat are exposed and are to be exposed, and what may be the outcome is not a matter of logical consistency, but of response to stimulus.

So, then, since Darwinian concepts have begun to dominate the thinking of the Marxists, doubts have now and again come to assert themselves both as to the inevitableness of the irrepressible class struggle and to its sole efficacy. Anything like a violent class struggle, a seizure of power by force, is more and more consistently deprecated. For resort to force, it is felt, brings in its train coercive control with all its apparatus of prerogative, mastery, and subservience.[12]

So, again, the Marxian doctrine of progressive proletarian distress, the so-called Verelendungstheorie, which stands pat on the romantic ground of the original Marxism, has fallen into abeyance, if not into disrepute, since the Darwinian conceptions have come to prevail. As a matter of reasoned procedure, on the ground of enlightened material interest alone, it should be a tenable position that increasing misery, increasing in degree and in volume, should be the outcome of the present system of ownership, and should at the same time result in a well-advised and well-consolidated working-class movement that would replace the present system by a scheme more advantageous to the majority. But so soon as the question is approached on the Darwinian ground of cause and effect, and is analysed in terms of habit and of response to stimulus, the doctrine that progressive misery must effect a socialistic revolution becomes dubious, and very shortly untenable. Experience, the experience of history, teaches that abject misery carries with it deterioration and abject subjection. The theory of progressive distress fits convincingly into the scheme of the Hegelian three-phase dialectic. It stands for the antithesis that is to be merged in the ulterior synthesis; but it has no particular force on the ground of an argument from cause to effect.[13]

It fares not much better with the Marxian theory of value and its corollaries and dependent doctrines when Darwinian concepts are brought in to replace the romantic elements out of which it is built up. Its foundation is the metaphysical equality between the volume of human life force productively spent in the making of goods and the magnitude of these goods considered as human products. The question of such an equality has no meaning in terms of cause and effect, nor does it bear in any intelligible way upon the Darwinian question of the fitness of any given system of production or distribution. In any evolutionary system of economics the central question touching the efficiency and fitness of any given system of production is necessarily the question as to the excess of serviceability in the product over the cost of production.[14] It is in such an excess of serviceability over cost that the chance of survival lies for any system of production, in so far as the question of survival is a question of production, and this matter comes into the speculation of Marx only indirectly or incidentally, and leads to nothing in his argument.

And, as bearing on the Marxian doctrines of exploitation, there is on Darwinian ground no place for a natural right to the full product of labor. What can be argued in that connection on the ground of cause and effect simply is the question as to what scheme of distribution will help or hinder the survival of a given people or a given civilisation.[15]
