The concept of depth is central to Merleau-Ponty’s phenomenology and informed not only his philosophy of perception but also his thinking about psychology, art and politics. This article traces the ways the notion of depth appears in Merleau-Ponty’s thinking in these fields, contrasting it with Husserl’s own phenomenological investigations. The article starts with a comparison of the function of perception in Husserl’s phenomenology and then proceeds with an analysis of how the issue of depth reappears in Merleau-Ponty’s phenomenology of perception, (...) phenomenology of art and political philosophy. I argue that while Husserl’s approach to phenomenology led him to analyses of aesthetics stemming from works of art as random examples, and to non-participation in politics, Merleau-Ponty’s phenomenology leads to the opposite approach, inviting concrete criticism in art and active participation in politics. It is argued that Merleau-Ponty’s approach is more philosophically consistent. The choice of particular works of art, and the particular political engagements, can retrospectively clarify the transcendental phenomenological investigations themselves. (shrink)
