Inferencia semiotica y semejanza en el De signis de Filodemo y en la escuela de medicina empirica. Semiotic inference and similarity in the De signis of Philodemus and the School of Empirical Medicine

With particular emphasis on the first century BC, the theme of Similareidad appears central in both fields of philosophy (Epicurean semiotic) and medicine (that of empirical medicine). In both cases the notion of Similareidad is used as the basis for semiotic inference, acted through a logical passage (or metabasis). However, in Epicureans, metabasis assumes different configurations with respect to that used by empirical physicians: for the former this is configured as a logico-semiotic passage of certain known entities to others not known; while for the latter, which do not accept indicative signs, this is to say that something not evident can be inferred from something evident, metabasis is configured as a passage from known phenomena to other known phenomena.
