The nineteenth-century appraisal of Whewell's philosophy as confused, eclectic, and metaphysical is still dominant today. Yet he keeps reappearing on the agenda of the historians and philosophers of science. Why? Whewell continues to be a puzzle. Historians evade the puzzle by deeming him to have had no serious philosophy but some interesting ideas and/or to have been socially important. Menachim Fisch's recent study offers promise of a new appraisal. But Fisch's account leads back to the puzzle. Fisch poses the question (...) well, promises a new answer, but does not provide one. The puzzle will remain until the strength of Whewell's turn away from empiricist problems to Kantian ones has been appreciated. (shrink)
