In this stimulating book, six leading philosophers - Karl-Otto Apel, Robert Brandom, Karsten Harries, Martha Nussbaum, Barry Stroud, and Allen Wood - consider the nature of philosophy. Although each of them has a unique perspective, they all seem to agree that philosophy seeks to uncover hidden assumptions and concepts in order to expose them to critical scrutiny. It is thus entirely fitting that philosophers should examine their own assumptions about the nature of their discipline. As they delve into the nature of philosophy, the authors address many fascinating subjects: what makes philosophy different from natural science, religion, and other branches of the humanities; whether philosophy can contribute to political transformation, and if so, how; and, whether there can ever be an 'end of philosophy'. The editors' introduction ties together the contributors' diverse perspectives by noting common themes, similarities, and differences.
