Charles Ashby Lewis, Evanston, ILI am a former investment banker who now chairs his family foundation, not a professional commentator.

I first wrote about Barack Obama’s presidential prospects in November of 2006 and went on to write over 100 commentaries about his campaign and presidency that I emailed to friends, colleagues and acquaintances across the country. I called them “Obamagrams.”: www.obamagrams.com If you have not read any of them, I recommend that you start with #1, then sample #22 and #58.

Then in 2019, I decided to support Mayor Pete Buttigieg’s presidential candidacy, considering him to be the closest analog to Barack Obama among the large field of Democratic candidates. I went on to write 10 commentaries about him which I called “PetePosts.”: www.peteposts.com

During the COVID-19 pandemic, I felt the need to write again.

Building on my previous series, I have decided to dub these “Exograms.” They are not intended to be political, in a partisan sense, but they will probably wander into that territory on occasion.

Exograms is a reference to my 2017 Memorandum on Chicago’s “Education Exoskeleton.”

I believe that an “exoskeleton” is a better metaphor than an “ecosystem” when describing the non-governmental actors of many stripes who have organically allied to help Chicago’s public schools.

I view an exoskeleton as a metaphor for community. An exoskeleton “supports and protects” an animal whereas an ecosystem connotes “competition” among animals and other living things, as in a food chain.

While the specifics of Chicago or of public schools in general may not interest you, I hope to make the metaphor more broadly useful as a conceptual framework within which to contemplate our current COVID-19 predicament and its aftermath, and the very future of our democracy.

If you think others would be interested in my Exograms, please pass them on. If you want me to add anyone to my list, please send their email addresses to me by using the “contact” button on this site.
