The CCA awards five Killam Prizes each year, one in each of five areas: Health Sciences, Social Sciences, Engineering, Natural Sciences, and the Humanities. The prize of CA$100,000 (approximately $78,000) each is to recognize “active Canadian scholars who have distinguished themselves through sustained excellence, making a significant impact in their respective fields.”
Of Professor Ripstein, the CCA writes:
Arthur Ripstein is a leading philosopher whose work has been at the forefront of renewed scholarly interest in the legal and political philosophy of philosopher Immanuel Kant. Ripstein has contributed to some of the most pressing conversations of our time, including those around the connections between individual responsibility and social equality, the legitimate use of public power, and the morality and legality of war.
The Killam Prizes were first awarded in 1981. Philosophers who have won the prize over the past decade include Thomas Hurka (Toronto, 2017), Paul Thagard (Waterloo, 2013), and Jean Grondin (Montreal, 2012). A full list of previous winners is here.
