A theory of reasoned knowledge is presented by developing and demonstrating the methodology of a novel skeptical critique designed to extend the epistemological practice of belief justification to an epistemological practice of reason justification. Analyses of the reasoning found in the theorizations of certain seminal philosophers and leading scientists will reveal how the absence of the epistemic justification of reason defaults to the use of an unjustified form of reason that runs the play of an unrecognized and unchecked dialectic between (...) epistemology and science. An alternative form of reason will be logically outlined and tested against the formalized skeptical critique in order for the newly recognized dialectic to be checked over reason with provisional epistemic justification. Zeno’s paradox and Green’s and Sellars’ critique of givenness are employed as argument functionaries of the reasoned knowledge theory. (shrink)

Garssen and van Laar in effect concede our main criticism of the pragma-dialectical approach. The criticism is that the conclusions of arguments can be ‘P-D reasonable’ yet patently unreasonable, epistemically speaking. The concession consists in the claim that the theory “remains restricted to the investigation of standpoints in the light of particular sets of starting points” which are “up to individual disputants to create” and the admission that all the relevant terms of normative appraisal have been redefined. We also discuss (...) their criticisms of the epistemic account of argumentation and argument evaluation and raise some new questions about the approach they defend. (shrink)
