In this article I explore how socially engaged artistic practice draws upon hybridity as a methodological approach advancing social justice. Through the case study of Theaster Gates’s To Speculate Darkly (2010), a project commissioned by the Chipstone Foundation of Milwaukee, Wisconsin, and shown at the Milwaukee Art Museum, I consider how socially engaged practice mobilizes continually shifting notions of postcolonial hybridity to help museums make meaningful symbolic reparations toward equality and inclusivity. The research is based on interviews I conducted with Gates and with the director and the curator of the Chipstone Foundation. The article will demonstrate that, with hybridity, artists have the potential to subvert hegemonic power structures and to inspire reconciliations between museums and communities. While such reconciliations generally involve complex processes with no clear end point, the evolving concept of hybridity is an effective vehicle to foster pluralistic institutions, cultural organizations characterized by practices built upon shared authority, reciprocity, and mutual trust. Theaster Gates refers to the methodology of hybridity as ‘temple swapping’, an exchange of values between seemingly unlike groups, in his case the black church and the museum, to explore their interconnections and relational sensibilities. Temple swapping, I aim to show, is a valuable metaphor through which to examine socially engaged artistic practice and its implications for museum ethics.
