About the ACPA

Since 1926, scholars and thinkers, mostly based in Canada and the United States, have forged a unique tradition and community known as the "American Catholic Philosophical Association." Steeped in classical sources and cultivating the Catholic Philosophical heritage, this tradition is known for creative engagement with major philosophers of every era and bold responses to the themes and issues of contemporary philosophy.
