recently been reading Theories of Everything by Milton K Munitz, essentially a catalogue of ancient history theorems of existence, early philosophical texts and some bits and pieces of modern works by Einstein and such. Pretty simple, I got it from one of those free libraries.

For some reason, the previous owner highlighted the entirety of Aristotle's On the Heavens and Copernicus' On the Revolutions of the Heavenly Spheres as well as Galileo's Dialogue Concerning the Two Chief World Systems. I've been trying to piece together why those specific pieces are high-lighted and I know the curriculum in this area doesn't cover the actual writings of the book in entirety so it's been a bit of a puzzle figuring out why the entire sections are high-lighted in blue-yellow highlighter.

"DUH" is written in black marker on the side of the book. Irony.

decent book regardless.
