Protecting Sight #131: A new way to explain explanation. A white cataract, Dodick’s preslice technique, adenosquamous carcinoma, and the Swiss Family Robinson. Surviving and thriving as a surgeon.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, short story or significant work.

Here’s today’s list:

1. Ted Talk – David Deutsch: A new way to explain explanation. “For tens of thousands of years our ancestors understood the world through myths, and the pace of change was glacial. The rise of scientific understanding transformed the world within a few centuries. Why? Physicist David Deutsch proposes a subtle answer.” (

So, what was wrong with that myth and with all prescientific thinking? And what, then, made that momentous difference? I think there’s one thing you have to care about and that implies testability, the scientific method, the Enlightenment and everything. And here’s the crucial thing: there is such a thing as a defect in a story. I don’t just mean a logical defect. I mean a bad explanation. What does that mean?
