 However, Luther then goes on to argue that precisely because philosophy is confined to reason that operates within empirical  constraints,[10]  and is unaided by revelation, faith, and scripture, it cannot hope to tell us the whole story about human beings and the world, for which the extra resources available to theology are required, which can thereby put all this in relation to God and so define “the whole and perfect human being” (1536, WA 39.I: 176/LW 34:138). This means that theology can not only treat God as fundamental in its account of efficient and of final causes (as creator, and as the source of eternal happiness and salvation respectively), but it also sees human beings in the light of the Fall and also of grace and salvation, in a way that reason without theology cannot fathom—and if it tries to do so, will distort in a fundamental way.
