Virtual Existentialism (2020, with Daniel Vella) This book explores what it means to exist in virtual worlds. Chiefly drawing on the philosophical traditions of existentialism, it articulates the idea that — by means of our technical equipment and coordinated practices — human beings disclose artificial worlds in which they can perceive, feel, act, and think.
Virtual Worlds as Philosophical Tools (2015) Who are we in virtual worlds? Will experiencing worlds that are not 'actual' change our ways of structuring thought? Can these worlds reveal new possibilities to philosophize? This book tries to answer these questions from a perspective that combines the philosophy of technology with virtual worlds research.
