Another kid on the epistemological block

And so it came to pass that a rival epistemology (the theory of knowledge, especially with regard to its methods, validity, and scope, and the distinction between justified belief and opinion)

wiped out ‘foundationalism’, (do you recall all those teachers who told you what the poem meant)

AND they did dispose once and for all of ‘essentialist’ thinking. 

By deploying new rhetorical, deconstructive and semiological tools, 

they thus believe that they have taken apart all the assumptions by which we imagined ourselves to be independent individuals in a world which  we roughly taught we knew.  

In their Copernican revolution, they despise or at best pity all who are still deluded by geocentric (having or representing the earth as the centre),
mystifications of our deluded epistemology.

Personally, I think they have a point.
