Research Seminar of the Professorship for Philosophy at the Faculty of Theology: "Analitic philosophy of religion and theology after Frege and Wittgenstein"

If the theology of Thomas Aquinas would be inconceivable without the philosophy of Aristotle and Neoplatonism, then that of Karl Rahner would be inconceivable without that of Kant and Heidegger. Similarly, liberation theology would not have come about without the philosophy of Marx, and process theology without that of Whitehead.

In today's philosophical landscape, analytical philosophy occupies a prominent, if not dominant, place alongside ‘continental’ philosophy, to which the above-mentioned philosophers belong. Does analytical philosophy, and in particular its two founding fathers, Gottlob Frege and Ludwig Wittgenstein, have an influence on theology?

A first attempt in this direction was made by Fergus Kerr: Theology After Wittgenstein. There is no theology after Frege yet. Certainly, however, analytical philosophy has given rise to what is known as analytical philosophy of religion, which has much in common with theology. Are there points of contact between contemporary ‘continental’ theology and ‘analytical’ theology, if such a thing exists?

The lecture series has two objectives: to examine topics in theology and philosophy of religion that are inspired by analytical philosophy, and to search for topics and problems that are common to contemporary ‘continental’ and ‘analytical’ theology.

The lectures are also designed as an academic workshop in the sense that they will attempt to identify paths for future research. The lectures will be held in German or English.
