Nozick’s is a split view. There is the morality of the side constraints, and there is the egoistic morality of the market, and they have essentially nothing to do with each other. From the perspective of either, there is no intrinsic reason to care about the other. A similar critique ultimately applies to Hayek’s otherwise very interesting take on a moral vision for a free society in The Fatal Conceit (1988).
Hayek believes human behavior is structured in three tiers. The lowest tier is instinctual and includes genetically supported behavioral patterns and impulses that evolved over the thousands of years of our hunter-gatherer prehistory. The second tier is that of culture. Cultural customs, traditions, mores, and practices are transmitted through social learning. They evolved through a blind, quasi-Darwinian process of relatively random variation and selection through the success or failure of those who adopt them. They are not the product of reason. Reason itself, which is the third tier, is a late product of this process of cultural evolution. It enables us to consciously and critically evaluate evidence, hypotheses, and proposals. It is the only self-aware capacity of the three, but it is a very weak instrument. It is almost entirely incapable of grasping the reasons or justification or purposes of our actions or of predicting their effects. Hayek believes reason across the board is highly overrated. It serves mostly as a source of post hoc rationalizations of our behavior. One should not trust reason, whether theoretical or practical, very far at all. (The hostility to reason betrayed in this book is stunning. But further discussion of this point is a topic for another time.)
The different tiers are the source of different and sometimes conflicting behavioral imperatives, particularly “moral” imperatives. Continue reading
