Continuing reading the Marsden book, a quotation in his final chapter sends me to my library to find C.S. Lewis's An Experiment in Critism (1961) and re-read that book's final chapter. From Lewis:
Literary experience heals the wound, without undermining the privilege, of individuality. There are mass emotions which heal the wound; but they destroy the privilege. In them our separate selves are pooled and we sink back into sub-individuality. But in reading great literature I become a thousand men and yet remain myself. Like the night sky in the Greek poem, I see with a myriad eyes, but it is still I who see. Here, as in worship, in love, in moral action, and in knowing, I transcend myself; and am never more myself than when I do.
