Heidegger and Sartre on the Problem of Other Minds

Existentialists such as Martin Heidegger and Jean-Paul Sar- tre have offered some interesting responses to the skeptical problem of other minds. However, their contributions are sometimes overlooked in the analytic study of this problem. A traditional view may think the existentialists focus on the ethical issues among conscious minds and take for granted that individuals’ experiences are within a world with others. This paper aims to identify and reconstruct two transcendental arguments on other minds from Heidegger’s and Sartre’s philosophy. I argue that their arguments are strong enough to ward off skeptics and suggest that their existential starting points and methodologies might be our best way out of the puzzle.
