  Both the EM and the Epicurean similarity mode (SM) of sign-inference move to the non-evident from the evident. We do not know how the opponents defined what is evident, but the SM starts from empirical generalisations that have been, in their turn, built up from individual observations, and, ultimately, from perceptions and feelings, these being two of the standard Epicurean criteria. The experiences of others (if reliable), accessed through research (historia), as well as things proved earlier, may also furnish suitable starting-points for the construction (sunthesis) of inferential transitions (metabaseis) to the non-evident. All this empirical input is most often referred to as ‘things hereabouts’ (ta par’ hêmin), and it stands in opposition both to perceptible things outside our experience, e.g., from living things here to those in chilly ‘Britain, if any’ (§1, v 35–6), and also to those that are in principle imperceptible, as from moving things hereabouts to atoms moving in the void.
