“Memory can be warped, it lies, it tells us what we want to hear. So part of this essay is a call to work beyond personal knowledge and thus beyond memory, to test that memory against other evidence in the world. Memory will rarely match that evidence very neatly, but this is a good thing. Discrepancy between memory and other evidence is not a problem—it’s the point. The reckoning, the true story, lives in the space of the contradictions.”
One of my favorites, from Philip Gerard in Brevity. I think it’s often quoted. It should be!
