In the previous post, I discussed F. A. Hayek's division of classical liberalism into two contending camps. Once alerted to this dichotomy, I began to see it everywhere. For instance, David Hume, whom Hayek clearly takes to be on his side, distinguishes two schools of philosophers in the following passage:
Moral philosophy, or the science of human nature, may be treated after two different manners; each of which has its peculiar merit, and may contribute to the entertainment, instruction, and reformation of mankind. The one considers man chiefly as born for action; and as influenced in his measures by taste and sentiment; pursuing one object, and avoiding another, according to the value which these objects seem to possess, and according to the light in which they present themselves. As virtue, of all objects, is allowed to be the most valuable, this species of philosophers paint her in the most amiable colours; borrowing all helps from poetry and eloquence, and treating their subject in an easy and obvious manner, and such as is best fitted to please the imagination, and engage the affections. They select the most striking observations and instances from common life; place opposite characters in a proper contrast; and alluring us into the paths of virtue by the views of glory and happiness, direct our steps in these paths by the soundest precepts and most illustrious examples. They make us feel the difference between vice and virtue; they excite and regulate our sentiments; and so they can but bend our hearts to the love of probity and true honour, they think, that they have fully attained the end of all their labours.
The other species of philosophers consider man in the light of a reasonable rather than an active being, and endeavour to form his understanding more than cultivate his manners. They regard human nature as a subject of speculation; and with a narrow scrutiny examine it, in order to find those principles, which regulate our understanding, excite our sentiments, and make us approve or blame any particular object, action, or behaviour. They think it a reproach to all literature, that philosophy should not yet have fixed, beyond controversy, the foundation of morals, reasoning, and criticism; and should for ever talk of truth and falsehood, vice and virtue, beauty and deformity, without being able to determine the source of these distinctions. While they attempt this arduous task, they are deterred by no difficulties; but proceeding from particular instances to general principles, they still push on their enquiries to principles more general, and rest not satisfied till they arrive at those original principles, by which, in every science, all human curiosity must be bounded. Though their speculations seem abstract, and even unintelligible to common readers, they aim at the approbation of the learned and the wise; and think themselves sufficiently compensated for the labour of their whole lives, if they can discover some hidden truths, which may contribute to the instruction of posterity.
One example of that "other species of philosophers" who springs easily to mind is
William Godwin, whose densely-written
Enquiry Concerning Political Justice is precisely the sort narrowly scrutinizing examination of human nature that Hume and Hayek treat with so much skepticism (although Hume, of course, predates Godwin). Godwin believed quite strongly in a moral order that could be approached through reason, and he made it the basis of his political philosophy that a society composed of free-thinking citizens could attain a moral consensus by exercising their minds. But this approach by no means leads Godwin into an embrace of totalitarianism, nor even to seek liberty "in government," as Hayek's quote from Francis Lieber scurrilously implies. Godwin was the first philosophical advocate of anarchism, after all. His rationalist (one musn't say "rational") approach to moral questions was meant not only to tear down immoral institutions, but also to reassure himself that under conditions of total liberty, men and women would still follow basic and "reasonable" morality by their own volition.
Of course, that's a difficult case to make. It rests the case for liberty on two very doubtful propositions: first, that there really exists some sort of universal and "Platonic" moral law, accessible by all rational beings; and secondly, that humans are the sorts of rational beings capable of and interested in pursuing that moral truth. No one has ever really convincingly argued in favor of the first proposition, and the second proposition is empirically refuted daily by the evening news.
Hayek's approach to the problem posed by morality and liberty is a refreshing one, and it employs the insights he gained as an economist in the debate over socialism. Hayek's essential idea was that the amount of information embodied in society is so vast that no central committee, no board of philosopher kings, and no single individual could ever possess it all. The progress of society depends on the freedom of individuals to use the limited information at their disposal to safeguard their own interests, to put into fruition their own plans, and to pioneer new ways of living. In this way, economic success will depend not on the theoretical talents of government mandarins, but only on the real circumstances of life, which will be discovered by trial and error. The task of living will become easier over time as people in society observe the plans of others, adopt those that succeed, and reject those that fail.
Hayek's vision of progress mirrors the biological process of evolution by natural selection -- although, as Hayek insightfully points out, the original inspiration for evolutionary ideas did not come from natural history, but from social history: "[T]here can be little doubt that it was from the theories of social evolution that Darwin and his contemporaries derived the suggestion for their theories." (
The Constitution of Liberty, p. 59) Just as Darwinian theory succeeds at explaining life by clipping away supernatural processes and teleological intentions, so too does Hayekian social evolution achieve great explanatory force by removing the improbable "leap of reason" from the world of "Is" to the world of "Ought" that rationalist ethics is supposed to be able to provide. Hayek argues that moral evolution occurs by small steps, and that mistakes are weeded away by impersonal forces. Social "institutions" take the place of neo-Darwinian "genes."
Institutions, in the Hayekian sense, need to be distinguished from the government ministries and policies with which they might be confused. The name instead refers to much broader patterns and practices within a society, including the mechanisms whereby specific policies are chosen. Institutions are the infrastructure of economic life, and the grammar of social interaction. The right to private property, the tradition of common law, and respect for contract are all examples of the institutions to be found in Hayek's "free societies." Hayek suggests that even very basic moral ideas and practices can be included in this category. Like genes, they can survive the death of the "organisms" that embody them -- individual cultures, in this extended metaphor. They are potentially immortal. Institutions are capable of reproduction by imitation and mutation by experimentation. They are either retained or eliminated by the numerous decisions of individuals in society. These individuals need not be ethical philosophers in order to decide which habits to adopt -- they need only be observant as to which practices promote their own welfare. Economic theory suggests that the decisions of welfare-maximizing individuals will tend to stabilize around mutually beneficial arrangements. These spontaneous arrangements then become codified as moral customs and social institutions.
Hayek's theory of moral evolution is compelling for the same reasons as Darwinian theory: to use
Daniel Dennett's terminology, both Hayek and Darwin replaced "skyhooks" with "cranes." Darwin succeeded in showing that the natural mindless processes of mutation and selective reproduction can generate the illusion of design, closing the explanatory gap previously filled by creator gods and other improbable hypotheses. Hayek eliminates the need for a transcendental Natural Law by showing how numerous social "laws" have arisen naturalistically, by a process which is not exactly mindless but which is nonetheless undirected.
Hayek's insights on cultural evolution were profound, but they were not quite as original or conclusive as Darwin's. As befits a student of social evolution, Hayek had many intellectual predecessors. Among these, the most important was probably Edmund Burke, who
famously argued against the French Revolution by claiming that overturning tradition in favor of a master plan leads us to lose the accumulated wisdom of our ancestors. In more recent years, ideas of cultural evolution have evolved in a new direction, as Richard Dawkins's neologism, the "meme," has taken over the cultural environment.
Memes are cultural replicators -- "viruses of the mind," as some have called them. Quintessential examples of memes include catchy tunes, political cliches, and annoying forwarded emails. Hayekian institutions clearly parallel memes in many ways, yet the two categories are not completely overlapping. Memes can be stored in individual brains, and they can be taken down and transcribed on pieces of paper or magnetic tape. Institutions, on the other hand, demand a social context. It makes little sense to consider the role of institutions such as common law, free markets, or even private property on an island with a single inhabitant.
Institutional evolution and "memetics" are both to be admired for the attempt at applying Darwinian lessons to the cultural sphere. Yet there are deep complexities in social life which frustrate any such program. Biological replicators -- i. e., genes -- mutate at random, and new variants are never rationally examined before being put into operation. Evolutionary improvements are solely the result of blind tinkering. On the other hand, cultural replicators -- both institutions and memes -- are the products of more or less intelligent human beings. It is true that an institution or an invention can prove to be a wild success, even when the originators of the idea have put little thought into their production. Yet most of the time, the most succesful ideas floating around the culture will be the result of intense intellectual effort. As Steven Pinker writes in
How the Mind Works, "[a] complex meme does not arise from the retention of copying errors. It arises because some person knuckles down, racks his brain, musters his ingenuity, and composes or writes or paints or invents something" (p. 209) .
I tend to think that the opposition between rationalist and empiricist liberalism is a red herring. Hayek, like Burke before him, provides a powerful warning to would-be reformers that they ought not to radically overhaul society in the hopes that they can reinvent all social institutions from scratch. The empiricist, evolutionary school provides us with reason to believe that many institutions work better than we think they do -- and certainly better than whatever hare-brained scheme we could come up with on our own. On the other hand, we are often confronted by institutions which clearly do not work at all. In those instances, we have no better path to improvement than reason, guided by our moral sensibilities. And when a society gets to be as corrupt and unjust as Europe was in the eighteenth-century, it's not surprising that lovers of liberty will prefer to take their chances on a revolution.
There has been an interesting discussion going on at
Positive Liberty in recent weeks. Please take a look at Timothy Sandefur's
opening remarks on Hayek; Jason Kuznicki's
reply (in dialogue format); Sandefur's
response; and his later
reflections on the conflict between Hayek and "constructivist rationalism."
