Unification in Physics and Philosophy International Workshop in Helsinki on May 11th 2019 The workshop is devoted to dealing with problems in physics and philosophy by unification. The basic idea is that a minimal ontological core of postulates or hypothetical laws of nature could provide natural resolutions to long-standing problems that are caused by disunification, and that cannot be properly resolved by focusing only on details of isolated topics. Unification is urgently needed, for in neither discipline do we find a commonly accepted ontological core or world-view that could function as a unifying base. In effect, the great majority of physicists and philosophers focus on specialized problems in isolated research areas. Physics is mainly practiced by developing mathematical descriptions for each isolated area with the help of heterogeneous postulates. On a unifying approach, mathematics should be coupled with hypothetical laws of nature in a unified core, which suffice for different research areas or scales of phenomena. Similarly, in philosophy there is a tendency to specialise in problems of a particular domain, say, what is time, what is persistence, what is causation, rather than to develop unified views of interrelated domains. Furthermore, attempts to address interrelations between physics and philosophy are rare, and when it is done the focus is again within particular domains. The purpose of this workshop is to bring together scholars with a mutual interest in a unified approach of this kind, in order to discuss particular unifying resolutions and more generally what a unified approach should look like. The questions to be discussed include (but are not restricted to): What are the central problems in physics and scientifically oriented philosophy? Can we identify postulates of a provisional scientifically and philosophically sound unified ontology? How do specific provisional postulates unify domains of inquiry that are currently separate and how do they resolve their central problems? What are the criteria by which one theory is to be preferred over another? How did the historical development result in the current situation in physics and philosophy?
