Charles De Koninck is known for participating in an acrimonious debate about the character of the common good and Catholic personalism in the mid-1940s. This is unfortunate because that debate clarified little, and it distracted attention from De Koninck’s important perspective on modernity. We need De Koninck’s philosophy of nature because it can aid us in understanding the achievements of modern science while serving as a bulwark against reductionism.
