Jonathan Schaffer is a Distinguished Professor in the Department of Philosophy at Rutgers University. He is an acclaimed metaphysician with a unique mind and approach to philosophy (and who has exquisite taste in epigraphs). Jonathan is best known for his work on monism, in which he contends that the cosmos is the lone fundamental object in reality, and on the grounding relation. He and Robinson begin by exploring monism, including its relationship to contemporary developments in physics, and then move on to the grounding relation, explicating just what this is and how it marks a departure from the dominant Quinean view of metaphysics.linktree: https://linktr.ee/robinsonerhardtOutline:Robinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.
