Abstract
In trying to understand St. Thomas’ doctrine on the unity of adequate knowing, one has to locate what he has said on this topic within a larger framework, what he means by being a human being. His personal doctrine, as it is classically interpreted, centers around what I refer to as the unity of a human being or a human person. In general St. Thomas has been interpreted as saying that the human soul has subsistence in its own right, but it is incomplete in nature, and it is related to its body in the unity of a human being as part to part.
