 In the history of logic, Łukasiewicz’s pioneering studies opened up a new and more fruitful interaction between the past and the present, and the rediscovery and new appreciation of figures from logic’s past “in the light of modern formal logic” has continued to this day, though not all of Łukasiewicz’s own views on how to approach Aristotle or the Stoics have stood the test of time. His work also helped to inspire those historians of logic from the Catholic tradition in Kraków, most notably Jan Salamucha and Józef Bocheński, who applied modern methods to the investigation of logical problems and arguments from the history of philosophy.
