R. G. Collingwood
Philosophers who appeal to process rather than substance include Heraclitus, Karl Marx, Friedrich Nietzsche, Henri Bergson, Martin Heidegger, Charles Sanders Peirce, William James, Alfred North Whitehead, Maurice Merleau-Ponty, Thomas Nail, Alfred Korzybski, R. G. Collingwood, Alan Watts, Robert M. Pirsig, Roberto Mangabeira Unger, Charles Hartshorne, Arran Gare, Nicholas Rescher, Colin Wilson, Tim Ingold, Bruno Latour, William E. Connolly, and Gilles Deleuze. In physics, Ilya Prigogine distinguishes between the "physics of being" and the "physics of becoming". Process philosophy covers not just scientific intuitions and experiences, but can be used as a conceptual bridge to facilitate discussions among religion, philosophy, and science.
