Walter Burley (or Burleigh; c. 1275 – 1344/45) was an English scholastic philosopher and logician with at least 50 works attributed to him. He studied under Thomas Wilton[1] and received his Master of Arts degree in 1301, and was a fellow of Merton College, Oxford until about 1310. He then spent sixteen years in Paris, becoming a fellow of the Sorbonne by 1324, before spending 17 years as a clerical courtier in England and Avignon. Burley disagreed with William of Ockham on a number of points concerning logic and natural philosophy. He was known as the Doctor Planus et Perspicuus.
