This richly illustrated essayistic text that asks us what it means to see the face of the other within the frame of evolutionary collectivity as described by the microbiologist Lynn Margulis. We are taken on a journey through her concept of the holobiont (a collective genetic assemblage) by a dog named Bobby that Emmanuel Levinas met outside a work camp during World War 2.  What develops is an intricate dialogue about historical violence, the limits of empathy, animality, collective responsibility, energy as an individuating force and what use science has in our current societies.
