Abstract

In this thesis I am going to explain the role of metaphor in articulation of new scientific theories, explicitly speaking, indeed, I have not a word about metaphorical thinking in theory invention, implicitly speaking. In fact, I talk about conceptual metaphor instead of linguistic metaphor. As another classification, this investigation belongs to “justification context”, rather than “discovery context”. Employing Boyd’ ideas on metaphor in science can lend a hand for acquiring this point. In Boyd’ set of beliefs; we need another reference theory which has not the problems of kiripki-pautnam’s reference fixing theory, thus, Boyd proposes the “epistemic-access theory of reference”. With accepting “interacting view” of Block on metaphor, he demonstrates that in this theory of reference we are not encountering the problems such as referent shifting, lack of precise of metaphor which exist in kripki-pautnam’s reference fixing. On the other hand, by admitting “relativity”, Kuhn criticizes the Boyd’s attitude on metaphor in science. To conclude, I defend kripki-pautnam’s reference fixing theory; since, it seems to be implausible to accept Boyd’s criticism.
