An Introduction to Metametaphysics

Tuomas E. Tahko is a University Lecturer in Theoretical Philosophy and a Finnish Academy Research Fellow at the University of Helsinki. He is the editor of Contemporary Aristotelian Metaphysics (Cambridge, 2012) and author of numerous articles in journals, including Mind, The Philosophical Quarterly, Erkenntnis and Thought.

'Tahko strikes exactly the right balance between introducing substantive metaphysical topics and exploring various metametaphysical considerations of those topics. An Introduction to Metametaphysics would make a splendid textbook for anyone offering an upper level course in metaphysics.' John Heil, Washington University, St Louis
