Javier Belastegui

Javier Belastegui is a PhD student in the University of the Basque Country, in Donostia-San Sebastian (Spain), where he finished his studies in Philosophy. He is currently working in a PhD thesis under the supervision of professor Thomas Mormann with a four year grant provided by the Basque Government. He has recently made a research stay at the Munich Center for Mathematical Philosophy in Munich. His thesis deals with the problem of natural kinds. The aim of the thesis is to develop a formal model for resemblance nominalism of kinds, which inevitably involves topological considerations. Besides kinds, he is interested into other topics in metaphysics such as essence, mereology and more generally anything related to formal metaphysics. He is a member of topological philosophy group at ICFO.

Janusz Kaczmarek
Janusz Kaczmarek

Janusz Kaczmarek – is a professor at the University of Łódź and an employee of the Department of Logic and Methodology of Sciences at the University of Łódź. In 1995 he defended his doctoral thesis on the Pragmatic and logical concept of a proposition. In 2009 he defended his second dissertation (the so-called habilitation) based on the monograph Indywidua. Ideas. Concepts. Research in the field of formalised ontology. Currently he deals with the problems of formal logic, philosophy of language and semiotics, but focuses mainly on the study of ontological problems and selected issues of philosophical anthropology. Ontological problems are most often explored by him in a formal way, i.e. with the use of logic, algebraic structures and recently also general topology tools. His main goal is now to create a new method of studying ontological problems (metaphysical), which is called topological ontology. The results of this work can be found, among others, in the papers: (2019), Ontology in Tractatus Logico-Philosophicus. A Topological Approach, (2019), On the Topological Modelling of Ontological Objects: Substance in the Monadology and in earlier papers in Przegląd Filozoficzny, Bulletin of the Section of Logic and others.

Wiesław Kubiś

Wiesław Kubiś, a researcher in the Institute of Mathematics, Czech Academy of Sciences, is a mathematician working mainly in applications of logic. In the last years, his research focuses on developing the theory of generic objects within the framework of category theory. The results have already found numerous, sometimes unexpected, applications in several areas of mathematics, including geometric topology, Banach space theory, and C*-algebra. One of his plans is exploring philosophical aspects of the theory of generic objects.
