The evolutionary significance of revolution
Introduction
Everything is evolution. Revolutions and collective normative learning processes are also evolutionary processes. Evolution never stops. But while evolution is, in a rough distinction, a process beyond plan and control, revolutions and (revolutionary and non-revolutionary) normative learning processes are specific kinds of evolutionary developments which not only proceed automatically as blind natural occurrences (naturwĂźchsig), but also express and perform our plans, intentions and ideas. Revolution is itself an evolutionary advance, in particular of the evolution of modern societies, even if it may have some forerunners that are premodern.
Like most theories of society, the critical theory of Karl Marx is an evolutionary theory. Yet even if Marx in his historical research clearly distinguished the historical analysis of class struggles from the functional logic of the capitalist system, he did not make much of this distinction systematically. In systematic concerns, his representation of the history of class struggles ultimately assimilates the normative developmental logic of the âhistory of class strugglesâ to the functional adaptation of the economic system to its environment. The reason is that Marx did not distinguish systematically between work and interaction.1 Therefore, Marx cannot explain the take-off of social evolution (I). Even if Marx in his historical essays understood the great European revolutions as legal revolutions, he retained a schema of basis and superstructure that reduced the basis to the economic system. It is not the schema that is the problem. All theories of society distinguish between basis and superstructure. For instance, Durkheim distinguishes the system of social division of labour from the collective consciousness of society; Parsons distinguishes the energy of a system (basis) from its ability to codify, organize and collect information (superstructure); Habermas distinguishes system (basis) and lifeworld (super-structure), and furthermore, the material (basis) from the symbolic lifeworld (superstructure) and Luhmann distinguishes the societal structure from the semantics of society. The problem with Marx is not the schema âbasis vs. superstructureâ, but his conceptual decision to give the economic system a kind of causal priority over all the other social systems, spheres of value and the whole superstructure. Therefore, he cannot develop a sufficient understanding of the normative peculiarity of revolution and the role of law as a âpacemakerâ of evolution that constrains blind evolutionary adaptation normatively (II).2 The most important of these normative legal constraints are constitutions. Constitutions are evolutionary universals. As universals they have a functional and a practical side. They are functional advances as well as practical mindsets (III).3 Constitutionalism presupposes a functionally differentiated legal system, and hence modern society. The last section gives a brief discussion of the internal relations between functional differentiation, crisis and social struggle in the evolution of modern society (IV).
I The power of the negative: The take-off of social evolution
Fifteen years before Darwinâs book On the Origin of Species (1859) was published, the epistemological implications of evolutionary theory were already made explicit in an unpublished manuscript by Marx and Engels that appeared much later under the title The German Ideology. From the middle of the eighteenth century onwards, evolutionary theory developed together with, and for a long time not really differently from, emerging modern historical scholarship and the (idealist) philosophy of history. Marx and Engels, at the end of the pre-Darwin period of evolutionary theory, summarized the results of the first hundred years of evolutionary theory in one short sentence: âWe know only a single science, the science of history.â4 The short statement that there is only one field of study, namely the study of history, has the epistemological implication that evolution overall is an empirical fact with a transcendental meaning. The meaning of âtranscendentalâ is âx being constitutive for yâ (or x limits the knowledge of y, and by limiting it enables the knowledge we have of y). Because everything is evolution, evolution is a quasi-transcendental fact that is constitutive for the reflexive knowledge of evolution that is itself part of evolution.
(1) Work, interaction and the growth of communicative negativity
There is only one evolution. But there are first different levels in the emergence of evolution: âOne can look at history from two sides and divide it into the history of nature and the history of men.â The two sides are âinseparableâ, are âdependent on each otherâ, but have different evolutionary histories.5 The evolution of evolution has led to the distinction between natural and social evolution. Therefore, Engels later called his and Marxâs theory historical materialism.6 In social evolution, so Parsons argues from a state of scientific knowledge a hundred years later, â(the) âgeneâ has been replaced by the âsymbol.ââ7 Yet this argument, in a nutshell, was already presupposed by Marx and Engels, the disciples of Hegel.8 Human beings are learning to invent and use their means of production through social interaction:
Men . . . themselves begin to distinguish themselves from animals as soon as they begin to produce their means of subsistence. . . . The way in which men produce their means of subsistence . . . must not be considered simply as being the production of the physical existence of the individuals. Rather it is . . . a definite form of expressing their life. . . . As individuals express their life, so they are. What they are, therefore, coincides with their production, both with what they produce and with how they produce. . . . This production . . . presupposes the intercourse [Verkehr] of individuals with one another.9
Social evolution begins with the socially learned cooperative use of instruments: âThe production of life . . . as a social relationshipâ consists in âthe co-operation of several individuals, no matter under what conditions, in what manner and to what endâ.10 Co-original with the social production of life is the production of communicative variation (consisting in the symbolic distinction between old and new needs) that finally leads to the take-off of social evolution. Marx and Engels call this take-off the first historical act: The âsatisfaction of the first need . . . leads to new needs; and this production of new needs is the first historical actâ.11
Henceforth, for Marx, the driving mechanism of social evolution is the symbolically mediated growth of productive forces. But Marx also considers another driving mechanism, namely, class struggle. He understands class conflicts as conflicts between social groups that are caused by the social structure of society. At the beginning of the Communist Manifesto, he and Engels assert: âThe history of all hitherto existing society is the history of class struggles.â12 Similar ideas on the evolutionary role of conflict were developed later by American pragmatists such as John Dewey.13 As all historical essays and studies of Marx and Engels show, class contest is about material as well as about ideal interests.14 But when he switches from the history of class struggles to the theory of society, Marx connects class struggle and the growth of productive forces in a way that eliminates class struggle as an independent evolutionary mechanism of change. Instead, he reduces the role of class struggle to that of a âmidwifeâ (Marx) of the unfettering of all productive forces. In the orthodox reading, the growth of productive forces (which leads to new symbolic expressions of ever new needs) is, therefore, the source of variation, and class conflict is the mechanism of selection that is re-stabilized by the relations of production. Therefore, Marx must explain the take-off of social evolution by the capacity to work. Work and technology, instrumental and strategic actions are learnt through social interaction. However, the learning of instrumental and strategic know-how is not specific to social evolution. Not only human beings, but also computers, great apes or students of law and economics can be involved successfully in communicative interactions of learning instrumental and strategic know-how. They all are able to learn socially. The actors of strategically restricted communication (like the homo economicus in game theory) learn cooperation with others for the single purpose of getting more for themselves at the end of the day. This is not due to the egoistic or greedy motivation of the actor, but to the strategically restricted system of communication. Marx already observed this in his basic distinction between the real-abstract personification of economic categories (which is related in strategic interaction with other existing categories) and the concrete person (and his or her altruistic or egoistic motivations). But, furthermore, learning âinstrumental actions from others sociallyâ must be distinguished from learning to follow reciprocally binding norms and the evolution of systems of such norms.15 Strategically restricted communication can never lead to the take-off of social evolution because the variety pool of negative communication does not grow quickly enough to reach the critical mass needed. Even the reciprocal use of symbols and reflexive symbols that replace other symbols (a=b) is not sufficient for the take-off of social evolution. Neither purposive rationality, that is, the ability to make practical inferences, nor the use of a universal language of binary codes that allows for identical transformations of meaning between different signs (propositionally differentiated language) can explain the take-off of social evolution. Such a language can exist as a medium of learning socially from others in groups of humans and other primates, of economists and computers, without causing social evolution. We cannot exclude that the strategically restricted use of language will once lead to a new form of evolution that is emancipated from genetic predetermination and ...
