As an aside, I took a History of Logic course from Krzysztof Apt (https://inference-review.com/author/krzysztof-apt/ https://inference-review.com/author/krzysztof-apt/) while I was an undergrad and he was briefly at UT Austin. He is an excellent teacher and a very nice man. (He loaned me a copy of a book on Frege's logic during the course---it had been signed and given to him by the person who let him stay on their floor when he first came to the US.)
