He taught at Oxford University along with Edmund of Abingdon. David Knowles said that he was "noteworthy for his knowledge of Avicenna and his rejection of the hylomorphism of Avicebron and the plurality of forms.", although the problem of the plurality of forms as understood by later scholastics was not formulated explicitly in Blund"s time. Maurice Powicke calls him the "first English Aristotelian."
Blund was a royal clerk by 1227 and studied at Oxford and Paris, and was at the University of Paris when it was dispersed in 1229.
He was a canon of Chichester before 1232.
He was archbishop of Canterbury during a brief reign, having been elected on 26 August 1232. He was appointed chancellor of the see of York before 3 November 1234, and died in 1248.
