Born on 25th November, 1925. He studied philosophy at Wroclaw University
under the supervision of Henryk Mehlberg and Maria Kokoszynska-Lutmanowa.
He received Master degree in 1950 and PhD in 1955 for the dissertation
"The philosophical significance of the Special Theory of Relativity".
In 1962 he presented habilitation dissertation under the title "Physical
Determinism". On the basis of this dissertation he was appointed
at Jagiellonian University as a dozent, and from 1971 as a professor.
Since 1977 he has worked at Warsaw University
His area of specialization comprises philosophy of physics, especially
ontology of physics. In the fifties he mainly worked on the problem
of causality and determinism. Later he focused on the issue of
philosophy of time, based on the Special Theory of Relativity. His main
results in this field concern (1) the nature of time (and spacetime), (2)
important properties of time, such as topological properties and
symmetry properites (anisotropy and homogeneity), (3) relationally
understood past, present and future, and their connections with
becoming and the existence. Since the mid-eighties he has been occupied
with construing the so-called point-eventism, which, according to his view,
constitutes an adequate ontology for the relativistic physics, and
implies set-theoretical realism.
Among his works are: The Properties of Time (1970, in Polish),
The Nature of Time (1974, in Polish), Time: Past, Present,
Future (1979 in Polish, reprinted and revised in English in 1991),
Possible Ontologies (1993), Essays on space-time (1996, in Polish).
