this collection brings together key contemporary texts in metaphysics. designed for students and general readers, it has a distinctive pedagogical aim: to enable readers to engage critically with challenging philosophical texts, and thereby use such texts as a springboard for their own philosophical thought and writing. each text is followed by a detailed commentary, which puts the authors views and arguments into context, explains key terms and argumentative moves, and most importantly asks a variety of questions. the questions are designed to prompt the reader to think critically about what the author is saying and why she is saying it, to think of objections, and to formulate and justify his or her own views on the topic.the book includes texts by kripke, lewis, parfit, armstrong, nagel, and dennett, amongst others, and discusses the following topics: free will, personal identity, realism and nominalism, modality, persistence, and realism and anti-realism.
