“LISP has been jokingly described as "the most intelligent way to misuse a computer."”
I think that description a great compliment because it transmits the full flavor of liberation: it has assisted a number of our most gifted fellow humans in thinking previously impossible thoughts.

I and Thou (1923)
Context: Some would deny any legitimate use of the word God because it has been misused so much. Certainly it is the most burdened of all human words. Precisely for that reason it is the most imperishable and unavoidable. And how much weight has all erroneous talk about God's nature and works (although there never has been nor can be any such talk that is not erroneous) compared with the one truth that all men who have addressed God really meant him? For whoever pronounces the word God and really means Thou, addresses, no matter what his delusion, the true Thou of his life that cannot be restricted by any other and to whom he stands in a relationship that includes all others.
