Introduction

A short journal article, published in The Philosophical Review in October 1974 and later collected in Nagel’s Mortal Questions (1979). Nagel chose bats because they find their way by echolocation, a sense unlike any of ours: we could know everything about a bat’s brain and still not know what it is like to be one. An organism has conscious experience, he proposes, if there is “something it is like” to be that organism. Nagel does not claim that physicalism – the thesis that everything mental is physical – is false, only that we have no concept of how it could be true. The article became a standard starting point for debates about qualia and the “explanatory gap”.
