This quote doesn't have anything to do with pipe smoking, but it's from one of my favorite pipe-smoking authors, Raymond Chandler.
There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art. Neither is independent of the other or more important than the other. Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from becoming ridiculous.
--- Raymond Chandler, ”Great Thought” (19 February 1938), published in The Notebooks of Raymond Chandler (1976)
