Query: Simply Incomprehensible!

The author of this book may be a great logician, but he compunicates his ideas extremely badly, making this book agonisingly difficult to read.The author is clearly not a native English speaker, and avoids explaining any concepts in depth, instead using page after page of Prolog code to demonstrate principles.This tiny book really isn't worth the paper its printed on.
