"The third project I would not like to leave unmentioned is LISP, a fascinating enterprise of a completely different nature. With a few very basic principles at its foundation, it has shown a remarkable stability. Besides that, LISP has been the carrier for a considerable number of in a sense our most sophisticated computer applications. LISP has jokingly been described as "the most intelligent way to misuse a computer". I think that description a great compliment because it transmits the full flavour of liberation: it has assisted a number of our most gifted fellow humans in thinking previously impossible thoughts."
"I must confess that I was very slow on appreciating LISP's merits. My first introduction was via a paper that defined the semantics of LISP in terms of LISP, I did not see how that could make sense, I rejected the paper and LISP with it. My second effort was a study of the LISP 1.5 Manual from MIT which I could not read because it was an incomplete language definition supplemented by equally incomplete description of a possible implementation; that manual was so poorly written that I could not take the authors seriously, and rejected the manual and LISP with it. (I am afraid that tolerance of inadequate texts was not my leading characteristic)."
Yeah, I always thought Dijkstra liked LISP because of the "the most intelligent way to misuse a computer"-quotation. When I read that text, I was completely confused.
