Čapek was strongly influenced by the process philosophy of Henri Bergson and to a lesser degree by Alfred North Whitehead.
[1] He was married to Stephanie Čapek (born Štěpánka Řežábková), who was a school teacher in Czechoslovakia and later a housewife, and died on July 14, 1998 (aged 82), in Little Rock, Arkansas.
Ten days before the Nazi invasion, Čapek left Paris and went to America after an odyssey via Dakar, Casablanca and a Vichy concentration camp in Morocco.
Milič Čapek made major contributions to the understanding of the philosophical implications of relativity theory and quantum mechanics, and to the philosophy of time.
[6] Čapek stated that the reason why we think of time and space as "space-time" and rather than "time-space" is because we give priority to the spatial aspect in our effort to geometrize events and moments, or to render them "space-like", as Einstein said.
