Here's a good sentence from Robert Anton Wilson's essay, "Synchonicity and Isomorphism in Finnegans Wake":
"Vico said that every verbal coincidence was a poem showing a new reality."
That's at the top of page 23 in my New Falcon edition, and it seems to be like a pretty good one sentence summary of the article.
I am no Joyce scholar, and I am counting on the James Joyce experts to weigh in, using the comments. I suppose everyone reading the article will have his own verbal coincidences that come to mind. Every time I see Joyce's name, I can't help think of another Joyce, a young woman I got a crush on in college at about the time I was reading Illuminatus! A verbal coincidence: Joyce's middle name is Elaine. My wife Ann's middle name is Elaine.
On page 21, Wilson mentions a Dublin bookstore named Brown and Nolan. Barnes and Noble, a bookstore with the same initials, is the last major bookstore chain standing in the U.S. -- if I had chosen to buy my copy of Coincidance at a bookstore rather than from Amazon, it's where I would have gone.
Wilson writes repeatedly of the two girls and three British soldiers who encounter H.C. Earwicker in the incident in Phoenix Park (page 10, for example); Wilson doesn't say so, but wouldn't this be an example of the Law of Fives? Also on page 10, Wilson offers the theory that the incident occurred at 11:32 a.m. When I got in my car Sunday morning to run the first errand of the day, trying to think of what I should write in this blog entry, I glanced at the clock in my car's dashboard and noticed that it was 11:32 a.m.
Wilson mentions on the last page of the essay that Ireland is divided into four provinces. Coincidance is divided into four parts, each of which has a James Joyce essay.
Reading Wilson's essay made me aware of more holes in my reading: I haven't read Tristam Shandy or The Golden Bough. I downloaded them both and put them on my Kindle. Reading the essay also reminded me that I simply have to read Frances Yates Giordano Bruno and the Hermetic Tradition. (As he often did, Wilson misspells her name as "Francis.")
