The concept of "the flesh" (la chair) derives from the writings of Maurice Merleau-Ponty. This was the word he used to name the concrete realm of sentient bodies and life processes that has been eclipsed by the abstractions of science, technology, and modern culture. Topology, to conventional understanding, is the branch of mathematics that concerns itself with the properties of geometric figures that stay the same when the figures are stretched or deformed. Topologies of the Flesh blends continental thought and mathematical imagination, opening up a new area of philosophical inquiry: topological phenomenology. Through its unique application of qualitative mathematics, this work extends the approaches of Merleau-Ponty and Heidegger so as to offer a detailed exploration of previously uncharted dimensions of human experience and the natural world.

The central thesis of this paper is that contemporary theoretical physics is grounded in philosophical presuppositions that make it difficult to effectively address the problems of subject-object interaction and discontinuity inherent to quantum gravity. The core objectivist assumption implicit in relativity theory and quantum mechanics is uncovered and we see that, in string theory, this assumption leads into contradiction. To address this challenge, a new philosophical foundation is proposed based on the phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Then, through the application of qualitative topology and hypernumbers, phenomenological ideas about space, time, and dimension are brought into focus so as to provide specific solutions to the problems of force-field generation and unification. The phenomenological string theory that results speaks to the inconclusiveness of conventional string theory and resolves its core contradiction.

This paper brings to light the significance of Merleau-Ponty’s thinking for contemporary physics. The point of departure is his 1956–57 Collège de France lectures on Nature, coupled with his reflections on the crisis in modern physics appearing in THE VISIBLE AND THE INVISIBLE. Developments in theoretical physics after his death are then explored and a deepening of the crisis is disclosed. The upshot is that physics’ intractable problems of uncertainty and subject-object interaction can only be addressed by shifting its philosophical base from objectivism to phenomenology, as Merleau-Ponty suggested. Merleau-Ponty’s allusion to “topological space” in THE VISIBLE AND THE INVISIBLE provides a clue for bridging the gap between “hard science” and “soft philosophy.” This lead is pursued in the present paper by employing the paradoxical topology of the Klein bottle. The hope is that, by “softening” physics and “hardening” phenomenology, the “two cultures” (cf. C. P. Snow) can be wed and a new kind of science be born.

This book addresses two significant and interrelated problems confronting modern theoretical physics: the unification of the forces of nature and the evolution of the universe. In bringing out the inadequacies of the prevailing approach to these questions, the need is demonstrated for more than just a new theory. The meanings of space and time themselves must be radically rethought, which requires a whole new philosophical foundation. To this end, we turn to the phenomenological writings of Martin Heidegger and Maurice Merleau-Ponty. Their insights into space and time bring the natural world to life in a manner well-suited to the dynamic phenomena of contemporary physics. In aligning continental thought with problems in physics and cosmology, topology is employed. Phenomenological intuitions about space and time are systematically fleshed out via an unconventional approach to this qualitative branch of mathematics. Topological phenomenology is applied to such topics as quantum gravity, cosmogony, symmetry, spin, vorticity, dimension theory, Kaluza-Klein and string theories, fermion-boson interrelatedness, hypernumbers, and the mind-matter interface.
