What is your authentic self—is it something that you design and create, or something to be discovered within yourself? The philosophical literature remains somewhat divided on this question, and this lack of consensus is also reflected in the popular sphere; in fact, ordinary appeals to the notion of an ‘authentic self’ often involve diverse, if not contradictory, views on selfhood. Interestingly, the self-help psychology of Canadian author and professor Jordan Peterson offers a particularly fitting example of this conflict. The argument (...) that Peterson makes for the importance of personal authenticity in his 2018 book, 12 Rules for Life: An Antidote to Chaos, highlights some of the metaphysical and moral challenges surrounding the concept. In particular, his portrayal of the authentic self demonstrates the degree to which conflicting views of selfhood can coincide: at the same time as his belief in biological essentialism supports a view of the self as genetically fixed, his appeal to social autonomy characterises the self as free and self-determined. Nonetheless, conceiving of the self as constrained in some aspects yet autonomous in others is not an inherently contradictory position. This chapter considers the extent to which these two visions of the self can be reconciled in Peterson’s work and, firmly situated as Peterson is within contemporary discourse, what his ideas on authenticity can tell us about the wider cultural debate.
