"Compared to its closest competitor, the recent Routledge Encyclopedia of Philosophy (Routledge, 1998), the Encyclopedia of Philosophy remains, as a whole, more accessible to students. This is not to say that student users will not be challenged to follow discussions of quantum mechanics, set theory or the works of Bertram Russell. Both sets serve scholars extremely well; however considering the substantial price difference, the Encyclopedia of Philosophy provides a more affordable option for libraries on tight budgets. -- Lawrence Looks at Books

"This encyclopedia will be useful to researchers, scholars, and students. It is written in clear, jargon-free English so that even the educated layperson will be able to use it easily. The Encyclopedia of Philosophy will find much use in larger academic and research libraries." --ARBA, March 2007

"Encyclopedia of Philosophy, second edition, is highly recommended for academic and public libraries and will be indispensable to most."

"The first edition of Encyclopedia of Philosophy, published in eight large volumes in 1967, was the standard philosophy reference for more than a generation. Now comes the second edition, offering hundreds of new articles, addenda to earlier articles, and updated bibliographies." Booklist, January 15, 2007

"While preserving many entries from the 1967 edition, this version adds 450 items on new topics and 300 newly authored versions of prior topics. New subfields like feminist philosophy and applied ethics are covered, as is the philosophy of love and sex in an excellent article by Alan Soble. The 'just war theory' entry should be required reading for all politicians." --Library Journal, April 15, 2007
