Bartosz Biskup is a philosopher, lawyer, a secretary of Jagiellonian Center for Law, Language and Philosophy and a member of Collegium Invisibile. During his studies, he was mostly interested in the philosophy of language (pragmatic-semantic interferences and theory of speech acts) and its implementation to legal problems and interpretation. Now he conducts research in social philosophy and ontology. His PhD research concerns the concept of marriage in the European Convention of Human Rights [within Preludium BIS I Grant, NCN; PI: prof. Adam Dyrda]. Nevertheless, his analysis is not legal in the sense of studying provisions. It aims to explain the presuppositions behind the concept and how marriage can be philosophically described as a social institution. He tries to find whether such a concept may embrace non-conjugal European families, as structures that do not resemble a nuclear family are disadvantaged and discriminated in social life. See a Pop-Sci podcast episode concerning of his PhD [in Polish]. Simultaneously, he is a Principal Investigator of a project concerning the artifactual character of law (Preludium, NCN). The primary question is what additional, comparing to social ontology, conceptual or theoretical utility the artifact framework gives us in scrutinizing law. Another is the relation between the artifactuality of law and the social source thesis (as discussed within general jurisprudence). Finally, the project also aims to determine whether both legal positivism and anti-positivism may accept any of the senses of artifact identified in the project. The artifactual framework may help to elucidate a minimal, standpoint-neutral meaning of the concept of law. Bartosz Biskup is also an author of two pop-sci papers concerning marriage and lying [in Polish].
