Walden East consists of essays on authors and themes, plus some content. There's splendid stuff about Fritz Leiber, for instance, and even some poems of the fantastic in House of Moonlight. Oh, and there are lots of reviews. All in all, it's a feast for the mind, especially when John tackles some of the more esoteric ideas found in Machen's work. And I can't resist ending with this Machen quote:
Yes, for me the answer comes with the one word, Ecstasy. If ecstasy be present, then I say there is fine literature; if it be absent, then, in spite of all the cleverness, all the talents, all the workmanship and observation and dexterity you may show me, then, I think, we have a product (possibly a very interesting one) which is not fine literature.
