What makes humans human? As science and technology challenge the boundaries between life and non-life, between the organic and the inorganic, this age-old question has become extraordinarily timely. Timothy Morton, a leading exponent of object-oriented philosophy, invites us to see this philosophical question as a deeply political one. In our relationships with non-human beings, we determine the fate of our humanity. Becoming human, Morton argues, really means building solidarity with non-human beings for a broader understanding of reality that both includes and transcends the notion of species.
