At the time the book was written the later chapters on models of induction and abduction were describing one of the better models of human thought. There is a strong emphasis on meta-interpretation as it was believed that exploration of these models by implementing them in more specific languages would be a path towards intelligence.

A more modern versn of this logical approach would be something like answer-set programming or other constraint based models of logic.
