I’m writing an essay called “Who Knows Two?” (to be made public a week from today) and would appreciate comments: https://mathenchant.wordpress.com/?p=2247&shareadraft=5acb8145805a2 Is my description of Frege’s work on number correct? What about my description of intuitionism? Is it okay that the article meanders so much, or should I restructure the opening to make it clearer where I’m going? Is there stuff I should cut or shorten (e.g., the Endnote about misreading Latin declension tables)? Or is there stuff I should add? (The piece is already on the long side, but if you know some really juicy things about primitive roots, I’ll consider adding them, or at least adding a reference.), As always, I hope you’ll sign your comments so that I can ask follow-up questions if need be. Thanks, Jim Propp
