Abstract
The term “critical thinking” is barely a century old; and it is controversial, fraught with ambiguity, and often treated as an academic orphan, condemned to the margins of scholarly culture. Despite its “royal” ancestry, as the embodiment of rationality inherited from Ancient Greece, it has come to represent an isolated and sectarian field of inquiry. But philosophers would be wise to take due credit for their offspring rather than shun or disavow critical thinking; and other scholars should recognize it as their shared legacy from philosophy, and the embodiment of intellectual rigor.
