Theaetetus by Plato is very difficult reading (it's Plato after all) that I'll have to reread. Nevertheless, I'm surprised by how much I love it! It will fry your brain (in a good way); you will agree with some things; you might not agree with everything (I don't), but you will be compelled to think deeply. I think, you are in for a treat with this one. Plus, if you are like me, you might find yourself to be the philosopher type of the page 72 and smile.
