The affirmation that one should not judge the historical past with current values forms a topic as widespread as the disobedience to it. However, a conscious exercise of the evaluative critique of the past allows us to identify continuities and disruptions in institutional patterns, i.e., in systems of incentives that are considered legitimate, whether by virtue of a question of social utility or principles.
Caste systems are obvious examples in which a differentiated attribution of rights, that is to say the legal protection of the interests of individuals assigned to a certain ethnic group, was interpreted as legitimate because it was a matter of principle.
While a caste is defined by an ethnic component, or at least with respect to its physiognomic marker, in the status system the ethnic differences lose preponderance, to transfer it to the different private orders or privileges that determine a function within the society. In both cases, both in the system of castes and status, it should be noted that they not only define privileges for its members but mainly establish obligations: war, worship or field work, for example. While the cult is reserved for a certain caste, in the status societies the cult is an institutionalized function, an order, whose members fulfilled certain procedures of admission and permanence.
In any case, beyond the similarities and differences in the systems of castes and status, what matters in this case is to emphasize that such attributions of rights and obligations, that is, of legal protection of interests, collective or particular, do not respond to a question of social utility but of principles. In the first place, because in such societies the power is fragmented and therefore there is no central power that can perform a critical judgment on the social utility of a given system of incentives; at the most, if there is a king, he assumes a role of primus inter pares, an arbitrator between castes or statuses or protector of order.
The emergence of central governments demanded the emergence of stable bureaucracies supported by a tax system to be systematized in a public accounting, that is, a calculation of utility. On the other hand, the incorporation of abstract procedures from private law to the administration of the government, displacing the systems of sages, mandarins, humanists, etc., allowed a better centralization and control and rational administrative decisions. However, what is important to note here is that such institutional innovations did not necessarily depend on a disruptive change, such as a revolution, but that many cases occurred through an evolutionary process, in which more efficient institutions displaced obsolete ones.
The emergence of central governments replaced fragmented political and social systems, because centralization allows a calculation of utility in decision making, which yields better results -not always but most of the time- than a decision system based mainly on honour. Most of the time but not always, since there is the possibility that, in a situation of extreme complexity, the calculation of utility has a wide margin of error and, in contrast, in such situations, a pattern of decisions based on emotions, traditions, or moral principles work as a kind of heuristic better adapted to the circumstances. After all, for the calculation of utility to be viable, it must have tools such as an accounting system, a literate bureaucracy, an abstract procedural system, among others. If you do not have such means, hardly a decision based on utilitarian issues is far from whimsical and arbitrary. Faced with such cases, traditional structures could be more efficient.
Another issue to consider is not to be confused between the rationalization of political power in a central administration – public budgets and control of their execution, a neutral and efficient tax system, administrative decisions of a particular nature adopted according to abstract and general procedures – with the rationalization of each subsystem of society and even of the individual in particular.
It is true that, as indicated by Max Weber, the bureaucratization of political power leads to the gradual bureaucratization of the rest of society: the generalization of the same accounting system for all companies, in order to verify compliance with tax obligations, the public instruction of the whole population, to name a few examples. These processes of rationalization are extremely beneficial and generate a jump in productivity. This is what William Easterly, in his work The Quest for Economic Growth, highlights as a phenomenon in which knowledge leaks and spreads throughout society. In this way the relations of complementarity generated by the knowledge shared with the rest of the individuals that make up a given community are much more important than the substitution effect could give an advantage to a single possessor of such knowledge. For example, having knowledge of accounting represents an advantage over the competition, but that all companies are organized according to reasonable and homogeneous accounting principles allows a jump in productivity throughout the system that yields even greater individual profits. Likewise, not only the leaking of knowledge is beneficial for all members of society, but reached a point is inevitable.
However, this does not mean that a rationalization of the society as a whole and of the individuals that compose it is necessarily possible or desirable; much less that such process is directed from a central political power. A process of compulsive and totalizing rationalization is not always modernizing. Both in biological and cultural terms, the evolution occurs in the margins, it is the mutations of small isolated populations that allow them to adapt to changes in the environment.
Moreover, the totalizing political systems, which not only seek to define from a central power each one of the functions of the social subsystems in function of a supposed calculation of utility, also seek to build a notion of “citizenship” that stifles the sphere of autonomy that defines each individual with civic obligations. Such conceptions are the first to see the processes of innovation and creative destruction and any individual initiative as dangerous. Thus, by cutting off all possible adaptation to changes in circumstances, by mutilating all possible discoveries, it is not uncommon for such political systems to experience stagnation and be displaced by other systems more open to innovation – or at least be invaded by results of said competition, discovery and innovation processes.
