This chapter examines the influence of the empirical sciences (e.g., physics, biology, psychology) in contemporary analytic philosophy, with focus on philosophical theories that are guided by findings from the empirical sciences. Scientific approaches to philosophy follow a tradition of philosophical naturalism associated with Quine, which strives to ally philosophical methods and theories more closely with the empirical sciences and away from a priori theorizing and conceptual analysis.

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)
