Questions of a metaphysical character have not been rendered obsolete by modern science. Rather, there remain pressing metaphysical issues both in dealing with foundational scientific problems – like the status of abstract objects in mathematics, or of the unobservable in physics, or of information in biology, and more generally, in dealing with problems that the human condition is entangled with, like the possibility of self-determination, the extent to which a social matrix of ideas is determined by “the Given” and the capability of our minds to grasp the inherent structure of reality. The entry point of our project is thus a firm belief that metaphysical questions are unavoidable even in the age of science and that the metaphysical aspects of scientific and other discourse ought to be made explicit and scrutinized. The aim of our project is to develop appropriate philosophical methods for doing so and to address specific metaphysical issues on that basis.
