The importance of the notion of verisimilitude, or truthlikeness, for a realist conception of knowledge was first realized by Karl Popper when he recognized that only the idea that a false theory can represent a cognitive progress with respect to another theory could reconcile his falsificationist epistemology with his belief in the rationality of science. This paper discusses Popper's 'syntactic' definitions of the comparative and quantitative notions of verisimilitude and then advocates a model-theoretic approach to the task of providing necessary and sufficient conditions for the truth of sentences of the form, 'B is truth-increasing with respect to A', where A and B are taken to be sets of structures.

Abstract
The importance of the notion of verisimilitude, or truthlikeness, for a realist conception of knowledge was first realized by Karl Popper when he recognized that only the idea that a false theory can represent a cognitive progress with respect to another theory could reconcile his falsificationist epistemology with his belief in the rationality of science. This paper discusses Popper's 'syntactic' definitions of the comparative and quantitative notions of verisimilitude and then advocates a model-theoretic approach to the task of providing necessary and sufficient conditions for the truth of sentences of the form, 'B is truth-increasing with respect to A', where A and B are taken to be sets of structures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
