Mark Letteri teaches philosophy in Windsor, Ontario, Canada, and hosts an occasional philosophy café and an online philosophical discussion group. He holds a Ph.D. in philosophy from the University of Waterloo, as well as an M.A. in philosophy and a B.A. in psychology from the University of Windsor. Dr. Letteri’s scholarly specialization is continental philosophy. His publications and presentations focus on Heidegger, Nietzsche, philosophical practice, reasoning, and educational development. Dr. Letteri oversees scholarly book series in existentialism and the philosophy of psychology. He is also a former first-year studies coordinator and general education teacher, as well as a former test writer and academic managing editor.

"Mark Letteri’s Heidegger and the Question of Psychology introduces psychologists and psychotherapists to a number of key ideas proposed by Martin Heidegger—the most influential and controversial philosopher of the 20th century. Letteri’s book is at once engaging and informative. Its scope of argument provides readers with a clear and accessible grounding for Heidegger’s concerns and their implications for the ways they might think about—and “do” —psychology. Revealing a depth of scholarly knowledge and acumen, Letteri challenges readers to consider Heidegger’s greatest challenge to psychology: to re-construe its dualist and reductive image of the human being. This is a book I unreservedly recommend to all professionals and trainees who view psychology as something more than a technological tool." – Professor Ernesto Spinelli, PhD, Director, ES Associates
