[Event at CIG] DEON Seminar Series Winter edition: January 27th – Fenrong Liu

[Huimin DONG]

The Society of Deontic Logic and Normative Systems (DEON) has launched an
online seasonal seminar series designed to promote interdisciplinary
cooperation amongst scholars interested in linking the formal-logical study
of normative concepts, normative language and normative systems with
computer science, artificial intelligence, linguistics, philosophy,
organization theory and law. We view the seminar series as an opportunity
to keep in touch with the DEON community and listen in or contribute to
presentations and informal discussions on ongoing work. Everyone who is
interested in this wonderful area and its questions is welcome.

We are happy to announce that our speaker for the DEON winter seminar will
be Fenrong Liu (Professor of Logic, Tsinghua University and University of
Amsterdam).

*Title*: From a two-level perspective on preference to deontic logic

*Abstract*: By 'two-level perspective on preference' I  mean the following
two aspects: a)  given a set of propositions, possibly ordered, we can
*derive* preference relations over individuals.  b) Given preference
relations between individuals, we can *lift* them to an ordering over sets
of individuals. After introducing the latest studies in these two lines, I
will focus on their relevance to deontic logic. In particular, I will
illustrate with the lifted Egli-Milner order and its connection to notions
of conditional ought and conditional permission.
