Theregisteredcompanyaddressis:VanGodewijckstraat30,3311GXDordrecht,TheNetherlands Preface to the Second Edition The second edition of the Encyclopedia of Medieval Philosophy is substan- tially revised and expanded from the first edition, which was published 10yearsago.Itwasalreadyatthattimethelargestreferenceworkonmedieval philosophy inEnglish(orfor thatmatteranylanguageasfar asIknow)and continues to be with almost 500 entries in the new edition. The expanded materialforemostconsistsofnewentriesonlesser-knownfiguresinmedieval philosophy.InallotheraspectstheEncyclopediaisthesameasthefirstedition andincludesentriesonphilosophers,concepts,terms,historicalperiods,sub- jects,andtheculturalcontextofphilosophyintheMiddleAges.Furthermore, itcoversLatin,Arabic,Jewish,andByzantinephilosophyandincludesentries onthecrossfertilizationofthesephilosophicaltraditions. AuniquefeatureoftheEncyclopediaisthatitdoesnotaimtodefinewhat medievalphilosophyis.Itsimplyaimstocoverphilosophybetweentheperiod 500 C.E. and1500C.E. It ismy belief that there isnothing thatis distinctly medieval about philosophy between these dates. Instead, philosophers and theologiansworked(asinothertimes)withthehistoricallygivenmaterialthat theyhadaccesstoandformedtheirownanswerstophilosophicalquestions, someofwhichwereasoldasphilosophyitself,whileothershademergedin thethinker’sownculturalcontext.Theiranswersweresometimesrestrictedby the culture and political atmosphere, and sometimes not. Some of these answersledtothedevelopmentofnewwaysofthinkingandconceptualizing the world, which were contrary to the traditional. This makes it possible to approachmedievalphilosophywithoutanypreconceivedideaofwhatphilos- ophy is or was, which allows the inclusion of all the facets of medieval thinkingthatmakeupphilosophyofthetime. A new feature is also that the Encyclopedia contains a table of contents, whichallowsthereadertogetafastoverviewofthecontents.Theentriesinthe Encyclopedia are organized in an A–Z format for easy access, as in the first edition.Eachentrybeginswithanabstractandendswithreferencestorelated entries and a bibliography divided into primary and secondary sources.

IhavereconceivedtheeditorialboardslightlyforthesecondeditionandI would like to thank theold board for their invaluable contribution. The new board,whichincludessomemembersfromthefirstedition,havebeenequally invaluable in finishing this new edition. The Encyclopedia is now online as v vi PrefacetotheSecondEdition well andexists asalivereferencework,whichmeans thatitiscontinuously updated and expanded. In that form, I hope it will live on for many more decades.IalsoneedtothankthestaffatSpringerReferenceforhelpingmeand forworkingtirelesslytomakethisworksuchagoodresource. Stockholm HenrikLagerlund June2020 Editor Preface to the First Edition Althoughtherearemanyhandbooks,companionsandhistories,thisisthefirst encyclopedia of medieval philosophy published in English. It is, therefore, withsomeexcitementthatIpresentitheretoyou,dearreader.Theaimofthis book is to provide scholars with an easy access reference work that gives accurateandtrustworthysummariesofthepresentstateofresearch.Itincludes entries on philosophers, concepts, terms, historical periods, subjects and the cultural context of philosophy in the Middle Ages. Furthermore, it covers Latin, Arabic, Jewish and Byzantine philosophy, and includes entries on the crossfertilizationofthesephilosophicaltraditions. As mentioned in the first edition, a unique feature of this encyclopedia is thatitdoesnotaimtodefinewhatmedievalphilosophyis.Itsimplyaimsto coverphilosophybetweentheperiod500and1500.Itismybeliefthatthereis nothing that is distinctly medieval about philosophy between these dates. Instead, philosophers and theologians worked (as in other times) with the historically given material that they had access to, and formed their own answerstophilosophicalquestions;someofwhichwereasoldasphilosophy itself, while others had emerged in the thinker’s own cultural context. Their answersweresometimesrestrictedbythecultureandpoliticalatmosphere,and sometimesnot.Someoftheseanswersledtothedevelopmentofnewwaysof thinkingandconceptualizingtheworld,whichwerecontrarytothetraditional.
