'''Richard the Sophister''' (Richardus Sophista) was an English philosopher/logician who studied at Oxford most likely sometime during the second quarter of the thirteenth century. Richard's identity is uncertain, but he is known to be the author of a collection of logically puzzling sentences, sometimes called “sophisms”, entitled Abstractiones, hence his title ''Magister Abstractionum''.
