Jaegwon Kim (born September 12, 1934, in Daegu; died November 27, 2019) was a Korean‑American philosopher noted for his careful analysis of the philosophy of mind. His work addressed how mental properties relate to physical properties, the nature of mental causation, and the problems facing nonreductive physicalist views. He was an emeritus professor at Brown University and taught at several other institutions in the United States.

Overview

Kim became widely known for arguing that many popular positions in contemporary philosophy of mind face difficult tradeoffs. He emphasized conceptual clarity and formal argument, and he brought attention to what has become known as the exclusion problem: if physical causes suffice to bring about physical effects, what causal work is left for mental properties? His essays were collected in volumes such as Supervenience and Mind, which helped shape debate in analytic philosophy.

Key ideas and concepts

  • Supervenience: a relation often used to express dependence of mental properties on physical bases.
  • Mental causation: the question of whether and how mental states can causally influence physical events.
  • Exclusion problem: Kim highlighted a prima facie conflict between causal closure of the physical and the efficacy of distinctively mental properties.
  • Reduction and realization: he explored whether mental properties must be reduced to physical properties or whether they can be regarded as realized by physical structures without ontological independence.

Career and influence

Born in Korea, Kim emigrated to the United States and became an influential voice in analytic philosophy. He published extensively on the metaphysics of mind and causation, and his writing combined technical rigor with attention to implications for broader theoretical positions such as physicalism, functionalism, and emergentism. His critiques motivated subsequent defenses and revisions of nonreductive physicalism and stimulated much literature on how to reconcile mental causation with a physically governed world.

Reception and legacy

Kim’s arguments are central fixtures in contemporary discussions: students of philosophy encounter his statements of the exclusion problem and debates over supervenience in courses on mind and metaphysics. While some philosophers took his conclusions toward reductionism, others developed alternative conceptions of causation or of higher‑level properties to preserve a distinctive role for the mental. His work remains a standard reference point for anyone dealing with the relation between minds and bodies.

He is often identified as a prominent Korean born scholar who became an important figure in American philosophy, and his writings continue to be cited and debated in contemporary literature.
