Abstract
A Sartrean existentialist ethics of authenticity model can serve as an alternative to traditional approaches to the issue of moral responsibilities to future generations. Traditional utilitarian and rights-based positions can fall short when addressing future-persons concern, both through technical problems and their failure to show our interconnectedness with other generations. Sartrean concepts of freedom, responsibility, and authenticity can offer an alternative approach which focuses on interpersonal adoption of the Other’s projects. There is bad faith present in the typical discussion about future generations. We need to rid ourselves of this bad faith in order to engage in authentic relationships with humans of the past, present, and future.
