The argument that Chaucer is in some way a cognitive science or an agent of a proto-cognitive science is certainly a complex one to make for three main reasons:
irst we must take into consideration that there is no evidence for or against Chaucer having any formal education of any sort, but we can speculate about certain things he could have been exposed to in schools and among other authors during the time in which he lived.
econd, Chaucer’s narrators are notorious for claiming humility and trying to distance themselves from the stories that they are recounting and the themes they are engaged in. This calls motive into question as well as the things that the narrator explores in the story, including his reflection pertaining to dreams.
hirdly, as with all analysis of literature, there is a fine line between forcing new reading methods onto texts and finding concrete evidence for a theory about a particular piece of literature.
