So, when I asked around for a list of people who seem Shimerian, one of the names that came up was Madeleine L'Engel. Yes, she is dead. (As are some Shimerians? Here is her obituary in case you want to learn more.) But yes, she is immortal because generations have read, are reading and will read, her work. And, yes, I have.
The work in question I have in mind is A Wrinkle in Time. But, of course, she wrote many more works than that.
Here are some speculations on why she is a Shimerian:
(1) Because time matters. Think of all the ways that temporality matters and that we think through the lens of time. Time flies when you are having fun. Time management (not so fun). Timing your comments in class. Thinking about what count as enduring questions (across time). Taking time to think through ideas. Reading books like Being and Time.
(2) Who can go through life -- and certainly who can go through Shimer -- without thinking about Mrs Whatzit, Mrs Who, and Mrs Which? Really?
(3) Tesseracts are cool. And yes, simply by thinking about this notion you are interdisciplinary -- bringing mathematics and literature together.
So, on this argument, Madeline L'Engel is a Shimerian because there are themes in her work which are connected to what we do (both what we read and what we do), there is a tiny bit of quirky silliness in all of this, and yes, she is all about the ways ideas connect with one another.
I admit I have not read A Wrinkle in Time in a long time. While L'Engel went to Smith and many of her papers are housed at Wheaton College in Illinois, though, I still think she qualifies as a Shimerian.
Have you read L'Engel's work? What do you think? Is she a Shimerian?
