This is the introduction of issue 1 of Mɛtascience. -/- This first issue of Mεtascience is a posthumous tribute to Mario Bunge, who died in February 2020. This is not the first time, and certainly not the last, that thinkers pay homage to Mario Bunge or that his work is the subject of study, and rightly so, because the man is a humanist and the work worthy heiress of the Enlightenment. Bunge has made a significant contribution to a wide range (...) of disciplines: physics, philosophy, sociology, psychology, cognitive sciences. This issue is also a way to make his thoughts known to a French-speaking readership. (shrink)
