Thomas Nagel

Thomas Nagel (b. 1937, Belgrade) is an American philosopher, long associated with New York University, and one of the most influential figures in late-twentieth-century analytic philosophy of mind, ethics, and political theory.

His 1974 paper “What Is It Like to Be a Bat?” (published in The Philosophical Review, later collected in Mortal Questions, 1979) became one of the most cited works in the field. Its argument is deceptively simple: there is something it is like, subjectively, to be a conscious organism, and this first-person character of experience cannot be captured by any purely objective, third-person physical description.

We cannot know what it is like to perceive the world through a bat’s echolocation, and no amount of neuroscience closes that gap. The essay crystallized the modern problem of consciousness and the notion of “qualia.” Nagel is a careful, secular philosopher, not a spiritual or mind-power thinker, and that distinction matters here.

In The View from Nowhere (1986) he explored the tension between subjective and objective standpoints, and in his controversial Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False (2012) he argued that consciousness, cognition, and value resist explanation within a strictly physicalist, neo-Darwinian framework, gesturing toward a non-reductive or teleological naturalism without endorsing theism.

Mind and Cosmos drew sharp criticism from many scientists and philosophers and remains a minority, speculative position; it is honest to present it as a serious dissent within philosophy, not a settled result.

Tier: legitimate philosophy (mainstream on consciousness, contested and speculative on anti-Darwinism).
