The 25th conference of the German Society of Philosophy deals with the true, the good, and the beautiful – and, therefore, with everything? Yes and no. As always, the conference will be an exhibition of philosophy and provide the opportunity to present research from all parts of philosophy: in 40 sections there will be talks about virtually all fields and periods of philosophy. At the same time, there will be, mainly in the colloquia, a focus on special questions, which have, in recent years, more and more taken centre stage in philosophical research. These questions are concerned with the relations between truth, goodness and beauty: What is the relation between epistemic and practical norms? Can judgements about the good and the beautiful be true (and false)? What is the value of truth? Is a good life a beautiful life? Is the aim of art beauty, truth or goodness? These and related questions are located at the intersection of theoretical and practical philosophy – and, therefore, maybe at the centre of philosophy in general.
