Hume on the Problem of Other Minds

Hume is not often cited as a philosopher who posited a solution to the Problem of Other Minds. He instead seems to assume the belief in other minds in his moral philosophy without justification. However, Hume needs to explain how we experience and respond to others’ affections, and hence generate moral sentiments, given how central the latter are to his moral theory. Two recent interpretations of Hume’s solution to the Problem are the Wittgensteinian Interpretation, and the Simulation Theory Interpretation. Both focus on the concept of sympathy as a solution to the Problem, claiming that, for Hume, sympathy produces the belief in other minds. This paper critically examines these two interpretations and offers an alternative called ‘the Analogical Argument Interpretation’, which reconstructs Hume’s version of an analogical argument carried out not by our rational faculty of mind but by custom and imagination. On this interpretation, Hume does not think that sympathy generates the belief in other minds, but rather, sympathy presupposes that belief.
