Without conservatism, social evolution would be as directionless as biological evolution. In social evolution, the endpoint is unobservable, but there are many arguments for its existence. Biological evolution is a two-way street; conservatism makes social evolution a one-way street (with many potholes and bumps, of course). In contrast, social evolution is teleological: It is incoherent, illogical, and intermittent, but ultimately, it has a directive principle toward a higher degree of freedom. The notion that societies mimic some features of biological evolution does not mean that they obey the same laws as living organisms.
