Morton's fork
A Morton's fork is a type of false dilemma in which contradictory observations lead to the same conclusion. It is said to have originated with the rationalising of a benevolence by the 15th century English prelate John Morton.
The earliest known use of the term dates from the mid-19th century and the only known earlier mention is a claim by Francis Bacon of an extant tradition.[1]
Dilemma
Under Henry VII, John Morton was made archbishop of Canterbury in 1486 and Lord Chancellor in 1487. He rationalised a benevolence (tax) of Henry's by reasoning that someone living modestly must be saving money, and therefore could afford the benevolence; whereas someone living extravagantly was obviously rich, and therefore could afford the benevolence as well.[2][1] Morton's Fork may have been invented by another of Henry's supporters, Richard Foxe.[3]
Other uses
