Abstract

Two topics are presently discussed. first, the distinction frege draws between two kinds of laws, natural and normative. secondly, we show how a remark made by frege with respect to different notions of truth is related to the analysis of meaning by family resemblances, as stressed later by wittgenstein. the historical dimension of family formation is discussed and references to 18th and 19th-century philosophers holding similar views are made.
