Series Editors’ Preface
Palgrave Innovations in Philosophy is a series of short monographs. Each
bookwillconstitutethe‘newwave’ofpureorappliedphilosophy,both
intermsofitstopicandtheresearchangle,andwillbeconcernedwith
‘hot’newresearchareasinphilosophyanditsneighbouringintellectual
disciplines. These monographs will provide an overview of an emerg-
ing area while at the same time significantly advancing the debate on
this topic and giving the reader a sense of where this debate might be
heading next. While the series will devote attention to core topics of
philosophy, itwillalsofeaturebookswithaninterdisciplinaryoutlook,

Preface
The guiding idea of this book is that a person’s normative standing in
the space of reasons is constituted by her explanatory standing. Thus,
theultimatejustificationofaperson’sbeliefsisconstitutedbyhowwell
those beliefs fit into a virtuous explanatory system which beats rele-
vant competitors. Epistemic justification is holistic because it depends
on the facts about a subject’s entire explanatory position. This book
presentsacasethatabelief’sepistemicjustificationisdeterminedbythe
explanatoryvirtuesofasubject’sentiresystemofbeliefs.
