How Do We See That Something Is Living? Synthetic Creatures and Phenomenology of Perception

Abstract

The creation of synthetic life forms raises the question of what we mean when we say that a synthetic cell is “alive.” This paper analyzes the problem of aliveness both as an epistemological question (how can we know?) and as a phenomenological question (how can we perceive?). It introduces basic concepts that can be used in a phenomenological analysis of the “givenness” of life and argues that aliveness can only be seen with reference to the experiences of the observer as him/herself living. Life is therefore inherently ambiguous. When perceiving other life forms, we are aware of our own life. In order to develop a concept of the “other life” of a synthetic bacterium, we need to be aware of projecting perceptual evidence of our own life onto that of other species. The concept of “other life” can address a very basic layer: seeing another life form’s being-in-the-world as (1) a center of its own spontaneity, (2) a particular way of being in time that can be described as duration, and (3) as a system of processes that contain their own sense as practices.
