Interesting, but the writing style is too long and winding. De Quincey often strays, and there are innumerable notes and footnotes. The first 200 pages are a general biographical sketch rather than his first-hand interactions. I did visit Dove Cottage in Grasmere and have been to other places he mentions, like Penrith Keswick, etc.
There is a funny quote from Southey about Wordsworth; he says, "To introduce Wordsworth into one's library is like letting a bear into a Tulip Garden." Quincey gives examples of how WW would rip apart pages or books while reading. Coleridge was much better and used to leave behind thoughtful comments beside the margin, unlike WW. According to Quincey, Coleridge, and Southey are more intelligent than WW. Southey was apparently more reserved and mostly talked about his books, dealing less with life (I like him ), while WW was animated and colorful.
Quincey criticizes Coleridge for delving into the Political economy, but I feel Coleridge was pretty good. For instance, in one case, Coleridge said that taxation is like moisture coming out of the ground, momentarily bad for nearby vegetation but better as a whole when it comes down as rain. In another case, Coleridge criticizes another economist who states that vine-dresser add nothing to the economy unless they earn a surplus. Coleridge states we should also take into non-monetary value, including personal satisfaction, and not judge solely based on money and productivity. This is a very modern approach, much like Michael Sandel. I would love to read Coleridge's essays.
Near the end Quincey talks about other lesser know lake poets like Charles Lloyd, Elizabeth Smith, etc. Quincey's relationship with WW soured near the end. The book also has his first letter, as a Cambridge student, to WW.
