To me, Lonergan’s existential experience of “conversion” is rooted in a model of human nature that is nested: intellect(moral(religious)).

Ironically, this nested model parallels the medieval (static, logical essential) model of anima (soul) joined to caro (flesh) by way of spiritus (an immaterial principle), once the medieval model is presented as nested:  anima(caro(spiritus)).

However, “parallel” does not mean “identity”.

To me, the parallel indicates that Lonergan – similar to many modern thinkers – assumes medieval definitions despite themselves.  This is not bad.  This is one of the ways to recognize postmodernism.

Postmodern thought channels medieval thought.
