In this new explanationist account of epistemic justification, Poston argues that the explanatory virtues provide all the materials necessary for a plausible account of justified belief. There are no purely autonomous reasons. Rather reasons occur only within an explanatory coherent set of beliefs.
"In this interesting book, Ted Poston delivers an original and powerful defence of explanatory coherentism about justification. ... an inspiring monograph that actually advances research in this field Scholars and postgraduates interested in the recent debate on coherentism about epistemic justification should definitely read this book." (Luca Moretti, The Philosophical Quarterly, Vol. 67 (266), January, 2017)
