A bit expensive. Just get Swi Prolog. https://www.swi-prolog.org/ https://www.swi-prolog.org/ The Simply Logical book as a start: https://book.simply-logical.space/src/simply-logical.html https://book.simply-logical.space/src/simply-logical.html you can get a PDF just fine. Also, for hardcore mode, get paper and pen, I'm not kidding: (again, just use SWI Prolog): https://www.ida.liu.se/~ulfni53/lpp/bok/ https://www.ida.liu.se/~ulfni53/lpp/bok/ Another approach. Scheme and Logic: S9 Scheme, get the bleeding edge version and compile it.
