Planner programming language

Planner (often seen in publications as "PLANNER") is a programming language designed by Carl Hewitt at MIT, and first published in 1969. Hewitt (then a student of Marvin Minsky, Seymour Papert and Mike Paterson) championed the "procedural embedding of knowledge" in the form of high level procedural plans in contrast to the logical approach pioneered by John McCarthy who advocated expressing knowledge declaratively in mathematical logic for artificial intelligence (AI). This raised a fundamental question: "What is the difference between the procedural and logical approaches?" It took several years to provide an answer to this question (see below).
