Abstract

In this essay I endeavour to discern a possible foundation for Hume's underlying assumption that human minds are similar to each other. The aim of this is to provide a new approach towards A Treatise of Human Nature that links Books II and III with Hume's epistemological discussion in Book I by providing a detailed analysis of the structural parallels and differences between sympathy and causal reasoning. Against this background, the belief in other minds will turn out to pertain to the class of natural beliefs which draw their legitimacy from Hume's attack on the metaphysical notion of reason.
