ABSTRACT
The aim of this symposium is to investigate several aspects of laws in the sciences of complex systems. The philosophical investigation of complex systems is still significantly underdeveloped in philosophy of science – in particular, the topic of laws in complex systems is a new area of research. In the light of typical features of the macro-behavior of complex systems (such as robustness, universality, non-linearity etc.), the contributions of this symposium will focus on three questions:
I. Is there an adequate explication of complexity? And, if so, which lessons can we learn from this explication regarding our understanding of laws, emergence and causation in the sciences of complex systems?
II. How can we explain the surprising fact that there are any robust and universal macro-laws at all?
III. How do facts about macro-laws metaphysically depend on micro-facts in complex systems? Is the lawful macro-behavior of dynamically complex systems emergent? And, if so, is the emergence at issue metaphysical or (merely) epistemological?
