Drawing on Berger and Luckmann’s discussion of reification, this paper examines the five aspects of essentialism that make the social construction of a seemingly objective reality possible. The five aspects are religion (as typically manifested in the idea of ‘God’), science (as typically manifested in the idea of ‘Nature’), reason (as typically manifested in the notion of ‘Logic’), universalism (as typically manifested in the notion of ‘Everybody’), and eternalism (as typically manifested in the notion of ‘Always’). They constitute the foundations of the process of making the merely intersubjective and conventional seem objective and inevitable.
