Stéphane Lupasco

Stéphane Lupasco, born Ștefan Lupașcu in Bucharest on August 11, 1900, was a Romanian philosopher who developed a new logic, questioning the principle of excluded middle (tertium non datur) in classical logic. His family, with Moldavian aristocratic roots, moved to Paris in 1916, where his mother, a pianist, established them. Lupasco studied philosophy, biology, and physics at the Sorbonne, and briefly law. He was deeply involved in the Parisian artistic and intellectual scene of the 1920s and 1930s, defending his State Doctoral Thesis in 1935. In 1946, he became a research assistant at the French National Science Research Centre but left a decade later due to the institution's inability to categorize his work. Despite limited acceptance by mainstream logicians and philosophers, his work gained public recognition, with "Trois Matières" (1960) becoming a bestseller. He was lauded by some as a major thinker of the 20th century. Lupasco continued publishing into the 1980s, with his final book, "L’Homme et ses trois éthiques," appearing in 1986. He received an award from the American Academy of Arts and Sciences in 1984. He was a founding member of the International Center for Transdisciplinary Research (CIRET) in 1987. Lupasco died in Paris on October 7, 1988. His work, inspired by Einstein and quantum theory, introduced a new logic with a "T-state" that transcends binary oppositions, extending to physics, epistemology, and consciousness.
