What is wrong with deductivism?

Abstract

In "Deductivism as an In-terpretative Strategy: A Reply to Groarke's Defense of Reconstructive Deductivism, " David Godden (2005) distinguished two notions of deductiv-ism. On the one hand, as an interpre-tative thesis, deductivism is the view that all-natural language argumenta-tion must be interpreted as being de-ductive. On the other hand, as an evaluative thesis, deductivism is the view that for a conclusion to follow, it has to follow of necessity from the premises-or, in other words, that being a good inference implies being deductive. The main goal of this pa-per is to show that evaluative deduc-tivism is wrong.
