Research interests

Foundations and Philosophy of Mathematics, in particular Logic.

Social Choice Theory, in particular Election mechanisms.



Prof. dr. H.C.M. (Harrie) de Swart (05-09-1944) was Professor in Logic and Language Analysis in the department of Philosophy at Tilburg University from 1980 till 2009. He studied mathematics and physics at Nijmegen University from 1962 till 1966, where he became assistent and later associate professor, first in the department of Mathematics and later in the department of Philosophy. He defended his Ph.D. thesis on intuitionistic logic in 1976 with Johan de Iongh as promotor. The academic year 1976-1977 was spent as Visiting Fellow in the department of History and Philosophy of Science of Princeton University, USA. Presently he is teaching logic and social choice theory at the department of Philosophy of the Erasmus University in Rotterdam.


Prof. de Swart has served as organizing chair of three international conferences and as program committee member in several others. He has published 16 books either as author or as (co-) editor, and almost 70 articles in academic journals. Up till now he was promotor of 19 Ph.D. students in different fields: logic and automated reasoning, logic and social choice theory, and foundations and philosophy of mathematics. Two more Ph.D. theses under his guidance are presently in preparation.
