Martial Gueroult (1891-1976) held the chair in History and Technology of Philosophical Systems from 1951 to 1952. Among his unpublished lectures at the Collège de France, the one on Kant from the year 1957-1958 is particularly important. The Archives Department has preserved the manuscript of over 650 pages, to which Gueroult returned on several occasions. Arnaud Pelletier, professor at the Université libre de Bruxelles, has just published it with The Collège de France Publishing Department in their new collection " Faire savoir ".
