It’s strange how the human mind swings back and forth, from one extreme to another. Does truth lie at some point of the pendulum’s swing, at a point where it never rests, not in the dull perpendicular mean where it dangles in the end like a windless flag, but at an angle, nearer one extreme than another? If only a miracle could stop the pendulum at an angle of sixty degrees, one would believe the truth was there.
[Graham Greene, The end of the affair,
Vintag 2019, p. 87]
