Add to ORKGConsider the long-debated principle concerning is and ought: IOP. There is no valid deduction of an ought (or ‘ethical’) statement from an is (or ‘factual’) statement. One very broad motivation for IOP comes from the thought (however vague) that ought statements are ‘funny ’ in a way that is statements aren’t. But whatever the motivation, IOP has long faced a short and sharp challenge from Arthur Prior [6]. LettingO be our unary ought operator, Prior’s now-well-known dilemma runs thus: • Let A be any factual statement, and OB any ought statement.1 • Dilemma: either the disjunction of A and OB is factual or ethical. • Case 1: A ∨OB is ethical. We may validly derive an ought from an is
