Research
The research of Maria van der Schaar concerns the philosophy of logic, including philosophy of language, and its history. Her historical research focuses on early phenomenology, the origins of analytic philosophy, and early modern philosophy. Her philosophical work stands in the tradition of intuitionism and Swedish proof-theory, especially the work of Per Martin-Löf, and she has proposed accounts of judgement, assertion, knowledge and meaning from this perspective. Unique in her research is the idea that the first person cannot be neglected in logic, and in philosophy in general. She aims is to bring problems in analytic philosophy to a deeper level of understanding by introducing ideas coming from phenomenology and the Kantian tradition.
