Kuhn, in Metaphors and Through , claims:
“Metaphors play an essential role in establishing links between scientific language and the world. Those links are not, however, given once and for all. Theory change, in particular, is accompanied by a change in some of the relevant metaphors and in the corresponding parts of the network of similarities through which terms attach to nature.”
Given that exemplars correspond to images of something concrete, and let scientists see similarities between similar problems, can examplars be seen as metaphors as well?
Which is the main sense of "metaphor in science" in Kuhn's philosophy?
