Abstract

There have been books written since 1997 both on Hume’s ethics and on metaethics generally which make no mention of Gerhard Schurz’s The Is-Ought Problem. I don’t say that they are ipso facto bad books since they may have merits which make up for this glaring defect. But Schurz’s magnificent The Is-Ought Problem is a major contribution to both logic and metaethics and ethicists who disregard it do so at their intellectual peril.
