Experimental Reason and Hypothesis

'Experimental Reason' can be defined as the 'faculty of Hypotheses'.  Strangely, despite his praise of Copernicus' innovative hypothesis, in the B edition Preface to the 1st Critique, Kant's only intensive consideration of Hypotheses, at B 798ff, is relatively dismissive of their significance.  Thus, the latter characterization, i. e. that an hypothesis is no more than a conditioned guess, demeans not only the Copernican revolution, but his own, as well, a self-described "experiment" from which his entire doctrine issues forth.  So, while many B edition passages reflect Kant's new-found appreciation of Bacon, B 798ff is not among them.
