Jean Ladrière (September 7, 1921 – November 26, 2007)[1] was a Belgian logician and philosopher, born in Nivelles. He was professor at the University of Louvain (UCLouvain)[2] from 1959 to 1986, where he was chair of the Higher Institute of Philosophy from 1977 to 1985.[3]
The overall project animating his work (650 scientific articles, partially assembled into a dozen volumes) was to develop, in his words, "a report that is not a simple confrontation, but a justified report to the both reflected and lived between the (Christian) faith and reason," especially scientific and philosophical reason.
