I’ve been reading Roland Hein’s book The Harmony Within, a study of GMac’s ‘vision.’ Heins provides a list of recommended secondary sources and I recognized one name - Stephen Prickett - and found a used hardback of his “Romanticism and Religion” for a few bucks and have been reading that as well.
The book (R&R) is an interesting study of GMac and some of his peers - Coleridge, Wordsworth, Longfellow, Maurice, Keble and a number of others. If you are into the literature and theology of their times (the Victorian Age, more or less) you will find this to be a stimulating read.
“The idea of poetic ‘creativity’ developed by Coleridge, Wordsworth and their successors in Victorian England, which is usually seen in aesthetic terms, was in fact a re-discovery and a re-application of a much older Judeo-Christian way of thinking about religious experience.…the result in early nineteenth-century England was that the elusive and yet clearly recognisable phenomenon, a ‘change in sensibility’, which makes the period characteristically different from all that had gone into shaping it.
We call that change in sensibility, loosely enough, ‘Romanticism’…the ambiguity of human experience: a sense of the continuing co-existence and conflict of the natural and secular ‘outer’ world with the ‘inner’ world of religious experience, sacred and felt as super-natural.” page 7. My emphasis.
Gmac and others have brought to life that sensibility which imo is drastically lacking in our current worldview; that lack leads to short-sightedness, the reduction of reality from its fulness, and other things.
