'You _are_ an argument for design,' said the theologian, taking no notice of the poet, 'though you won't admit it. Why won't you take up with my scientific religion?—a religion, you know, that can be expressed with equal facility by emotional or by mathematical terms. It is as easy, when you once understand it, as the first proposition in Euclid. You have two points, Faith and Reason, and you draw a straight line between them. Then you must describe an equilateral triangle—I mean a scientific religion, on the straight line, F R—between Faith and Reason.' 'Oh!' said the professor. 'How do you do it?' 'First,' said the theologian hopefully, 'taking F as your centre, F R as your radius, describe the circle of Theology. Then, taking R as your centre, F R as your radius, describe the circle of Logic. These two circles will intersect at Science, indicated in the proposition by the point S. Join together S F, and then join S R, and you will have the equilateral triangle of a scientific religion on the line F R S.' 'Prove it,' said the professor grimly. 'Science and Faith,' replied the theologian readily, 'equal Faith and Reason, because they are both radii of the same circle, Man being the Radius of the Infinite. Theology—' 'Stop!' ejaculated the professor in the utmost indignation. 'What do you mean by it? I never in my life listened to such unmitigated nonsense. Who gave you leave to talk of a scientific religion as an equilateral triangle? If it is a triangle at all, which there is not the remotest reason to suppose—but I cannot argue with you? You might as well call it a dodecahedron, or the cube root of minus nothing.' 'Oh, very well,' said the theologian with exasperating coolness. 'I thought it possible that even your blind prejudice might not refuse to listen to a simple mathematical demonstration of the possibility of a true scientific religion, but I find that I was mistaken. I am not annoyed—not at all. I prefer to look with lenity upon this outburst of passion, which might, I admit, have roused the anger of a theologian of the old school. But, believe me, I personally feel towards you no enmity—only the profoundest compassion.' Inarticulate sound from the professor.
