Abstract
In the past Boethius was primarily considered to be the author of the Consolatio, or a theologician or logician. But as a philosopher he was the first to reflect on the concept of person, while Augustinus and others only made use of this concept. It is the purpose of this article to show that it was exactly Boethius’ situation in the late antiquity with its many differing traditions that urged and enabled him to ask himself what person essentially is. His new concept of person (: naturae rationabilis individua substantia) puts person first and strengthens - problematically - the position of substance.
