The eye’s mind

  • September 29, 2021
  • 14 min

Welcome back folks! Today, we’ve got an audio essay for you. I won’t say too too much—don’t want to spoil it—but it’s about pupils. Not as in students, but as in the dark cores of our eyes. This one of those that’s been in the works for a little while. About a year ago I started collecting all the cool new pupil-related stuff coming out. Then at some point this summer some extra cool stuff came out and I said, “That’s it—time to do it, time to pull this material together into some kind of episode.” So that’s what we have for you today. And I hope you find it eye-opening.

Quick reminder before we get to it: As always, we could really use your help in getting the word out about the show. That might mean subscribing, if you don’t already. It might mean rating or reviewing us on Apple Podcasts. It might mean sending the show to a friend or two. I mean honestly it could mean knitting a Many Minds cardigan for the cold months ahead and sporting it around town. Ceaselessly.

Alright all, on to this week’s essay ‘The eye’s mind.’ Enjoy!
