In this paper, I discuss Lonergan’s account of the structure of the human good and then demonstrate how it works in reference to a doctor’s description of her experience at a New Orleans’ hospital in the aftermath of Hurricane Katrina. Next, I proceed to define health and disease on the basis of Lonergan’s accounts of the human good, emergent probability and generalized empirical method. Then, I lay out the generic levels of human living in a table of terms whose interrelations embody the multiple dimensions of health and their dynamic potential for integration (and breakdown) in the GEM model of health.
