Walter Burley is mostly known for his defense of realism against William of Ockham. The concept of time that he developed in his late literal commentary on Aristotle's Physics has even been labelled 'extremely realistic,' in contrast to William of Ockham's so-called 'extremely subjectivistic' alternative. However, as is shown in this article, when Burley's concept of time is viewed against the background of medieval theories of time, it appears that it is mainly a restatement and further elaboration of opinions held (...) by Averroes. A detailed investigation of Burley's explanation of the reality, definition, and unicity of time, as well as of the relation between time and the intellective soul shows that his realism is certainly far less extreme than it has been believed.
