This thread's title comes from a blog by Dr. Dimitra Fimi, a well-regarded scholar of Tolkien and fantasy. Her thoughts in the blog struck me as interesting for our discussions here, where we often quote Tolkien's letters as the definitive take on a topic or idea. Yet as Dr. Fimi suggests, there are different ways of reading, different pleasures. And, those pleasures may depend on the type or mode of fantasy an author uses.
Is this a helpful distinction, between readers who read for immersion in alternate worlds and readers who enjoy simply the possibility of alternate worlds without the saturation? I've always been bemused by Tolkien's defense of "applicability" and the freedom of the reader with his attempts in his letters to explain how his Legendarium ought to be read.
