Decent Essays

In this paper, I will begin by briefly explaining both what defines a natural kind term and what the description theory of the meaning and reference of natural kind terms is. I will then proceed to outline Hilary Putman’s argument where his main goal is to defeat the descriptive theory and provide a thesis of that of the following, only one being true, and not both: knowing the meaning of a term is just a matter of being in a certain psychological state, and that the meaning of a term determines its extension. Putnam gives two examples to further explain his claim. In regards to his twin earth thought experiment, he concentrates on the idea that meaning is reference. Building off of the twin earth thought experiment, he then provides more …show more content…

In other words, intention entails sameness of extension, as Putnam puts it.
Putnam’s Argument Hilary Putnam’s account of what makes up a natural kind term relies on our definition stated above, in which he believes natural kind terms hold true in all of nature (this is an important point) through being a rigid designator, or indexical. He believes that
