Is it Always Fallacious to Derive Values From Facts?

Argumentation 9 (4):553-562 (1995)
Charles Pigden has argued for a logical Is/Ought gap on the grounds of the conservativeness of logic. I offer a counter-example which shows that Pigden’s argument is unsound and that there need be no logical gap between Is-premises and an Ought-conclusion. My counter-example is an argument which is logically valid, has only Is-premises and an Ought-conclusion, does not purport to violate the conservativeness of logic, and does not rely on controversial assumptions about Aristotelian biology or 'institutional facts.'
