Specific reifications are variations on this general theme. Marriage, for instance, may be reified as an imitation of divine acts of creativity, as a universal mandate of natural laws, as the necessary consequences of biological or psychological forces, or, for that matter, as a functional imperative of the social system. What all these reifications have in common is their obfuscation of marriage as an ongoing human production. [...] Through reification, the world of institutions appears to merge with the world of nature.
