"As Oliver Cromwell said to the General Assembly of the Church of Scotland, "I beseech you, in the bowels of Christ, think it possible that you might be mistaken." Life and the affairs of the living are so tangled, the world not only stranger than we imagine but stranger than we can imagine, that all questions are conundrums, no answers "correct." Is it certain that parallel lines never meet? No. Does water freeze at 32 degrees Fahrenheit? Only probably. Shall I marry? Who can say? And yet the world's work must be done. One Oblomov is enough. Thus we learn a conventional certitude, acting as though all were light by blinking the shadow. A simple proof demonstrates that parallel lines do meet, but, on the assumption that they do not, the architect builds the skyscraper. Despite his knowledge of statistical mechanics, the engineer designs the refrigerator to maintain a constant temperature of 31 degrees. Le cœur a ses raisons que la raison ne connait pas [the heart has its reasons that reason does not know], and families are raised."
