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.

To discuss moral behavior in organizations, a growing number of authors turn to a ‘virtue ethics’ approach. Central to this approach is the so-called moral character of individuals in organizations: a well-developed moral character enables organizational members to deal with the specific moral issues they encounter during their work. If a virtue ethics perspective is seen as relevant, one may ask how organizations can facilitate that their members can exercise and develop their moral character. In this paper, we argue that (...) the way tasks are defined and interlinked has a profound influence on “exercising and developing moral character”—it can enhance and frustrate it. In order to show how structures may support organizational members to exercise and develop their moral virtues, the paper first describes what it means to exercise and develop virtues in an organizational setting and what is required for it. Next, the paper sets out to explain how specific values on different structural parameters at different structural levels relate to exercising virtues in organizations. (shrink)
John R. Searle is one of the world's leading philosophers. During his long and outstanding career, he has made groundbreaking and lasting contributions to the philosophy of language, to the philosophy of mind, as well as to the nature, structure, and functioning of social reality.

Searle on his overall philosophical enterprise entitled "The Basic Reality and the Human Reality". -/- "I think Münster is probably unique among contemporary universities in its ability to produce such a high level of philosophical production from their philosophy students." - John R.

In the 1970s Codd introduced the relational algebra, with operators selection, projection, union, difference and product, and showed that it is equivalent to first-order logic. In this paper, we show that if we replace in Codd’s relational algebra the product operator by the “semijoin” operator, then the resulting “semijoin algebra” is equivalent to the guarded fragment of first-order logic. We also define a fixed point extension of the semijoin algebra that corresponds to μGF.
