Reinhard Muskens: Calculi for Logics of Thinking Computers and Computer Networks

Lecture by Reinhard Muskens (Tilburg), organized by Grolog

In a now famous paper published in 1976, Nuel Belnap argues that computer reasoning should be modeled on the basis of a four-valued logic in which each value is a combination of the two classical values. Belnap also considers two lattices on these four values, one corresponding to increase in truth and non-falsity, the other to increase of information. Together these two lattices form what is now called a /bilattice/.

More recently Yaroslav Shramko and Heinrich Wansing (2005) have in a sense repeated Belnap's move, arguing that the logic of the reasoning of computer /networks/ should be 16-valued, with each value corresponding to a set of Belnap's values. They consider what is called a /trilattice/ on these 16 values and distinguish between an entailment relation based on the notion of truth and one based on falsity. These two relations are not equal or each other's inverses.

In this talk, which reports on joint work with Stefan Wintein, I will look at syntactic characterisations for these logics, with particular reference to...(continue reading)...

Herman Philipse: Global Evolutionary Debunking Arguments in (Meta-) Ethics Revisited

Lecture by Herman Philipse ( University of Utrecht, The Netherlands), organized by the Department of Ethics, Social and Political Philosophy

In the wake of Sidgwick and Moore, most philosophers seemed to agree that “Evolution has very little indeed to say to Ethics” (Moore 1903: 109). In recent years, however, so-called evolutionary debunking arguments (“EDAs”) have become popular among moral philosophers. According to some, evolutionary explanations of our moral intuitions are “highly significant for normative ethics” (Singer 2005: 343). In this paper, ... (continue reading)...

Ulrike Hahn: Argument Quality: A Bayesian Perspective

Lecture by Ulrike Hahn (Birkbeck University of London), organized by the Department of Theoretical Philosophy

How to measure argument quality is a topic of concern for many disciplines. One long-standing tradition has sought to characterise everyday informal arguments in terms of typical 'schemes' and associated critical questions that may be used for argument evaluation. The talk will discuss...(continue reading...)

Julien Murzi: Naive Logical Properties and Higher-Order Reasoning

Lecture by Julien Murzi, organized by Grolog

Elia Zardini (2013) and Hartry Field (2014) have recently argued that a key semantic ingredient of the v-Curry Paradox, a validity-involving version of Curry's Paradox, is in tension with Goedel's Second Incompleteness Theorem. Moreover, Zardini points to some paradoxes of consistency and incompatibility which, in his view, 'cannot be adequately solved by simply changing the logic' of one's theory, but rather...(continue reading...)

Workshop on Kant's Formula of Universal Law

The Formula of Universal Law is widely considered to be Immanuel Kant’s most important articulation of the principle of morality known as the Categorical Imperative. Yet it is thought, even among Kant scholars and Kantian moral theorists, to face insoluble philosophical problems. As a result, the Formula of Universal Law has fallen out of favor, and Kantian ethicists increasingly turn to the Formula of Humanity to complement it or replace it altogether. In this workshop, four new strategies for a philosophical ‘rehabilitation’ of the Formula of Universal Law will be presented and discussed.

Speakers: Oliver Sensen (Tulane), Sven Nyholm (Cologne), Jochen Bojanowski (Groningen), Pauline Kleingeld (Groningen).
