This is my second time attempting this book--this is a thorough work that delves into unpublished works in addition to published and, for a non-scholar, asks for a slower, more aware reading than previous works by the same author.
I found this book well worth the effort for the wide grounding in historical aspects of theories of time, exposure to unpublished but fascinating works (part of the challenge in reading was suppressing the my internal grumbling about not having a finished version of The Notion Club Papers), and for the ways that time dislocations lead to a comparison of war and Faerie. Notwithstanding the specificity of the discussion, this opened up my idea of what it means to write/read fantasy against a scientific understanding of nature.
My one caveat was that I would have preferred an anthology containing some of the poems mentioned (such as The Sea Bell) so that I could refer to a text within the book itself.
