Abstract

The distinction between activity and passivity has a deep and fundamental role in scientific and philosophical conceptual frameworks, going back to ancient Greek thinking about society and nature. I briefly indicate the importance of the activity-passivity distinction in the phenomenology of Merleau-Ponty, in relation to Husserl. I then advance a transcendental phenomenological argument that the distinction is, however, not as simple or obvious as it might appear, specifically that it cannot be wholly and determinately defined via a purely abstract, conceptual-discursive procedure, since specifying which of two interacting terms is the active one entails (I argue) an implicit reference to pre scientific, affective experience. But, as I argue, specifying this distinction is nonetheless conceptually fundamental for scientific thinking about nature, especially in biology, despite scientific efforts to abstract from it. Together these arguments amplify, within science itself, Husserl’s and Merleau-Ponty’s point that life, as intrinsically involving affect, is a transcendental condition of science.
