The article describes the evolution of Ockham's theory of mental language and its impact on three of his dominican contemporaries at oxford: Hugh Lawton, William Crathorn and Robert Holcot, and its impact at Paris on the works of Gregory of Rimini and Pierre d'Ailly. Hugh Lawton's critical response to Ockham relied on a liar-like paradox to show that mental language would preclude the ability to lie. Crathorn devised an alternative to Ockham's theory in reaction, whereas Holcot defended Ockham's views. At (...) Paris, the debate suggested a solution to the liar paradox to Gregory of Rimini.
