We Can No Longer Be Sure Of Anything
The brain does not see a thing. Most of its energy is consumed predicting in darkness. At last we understand why we only see what we want to see, just as the moon looms larger on the earthly horizon than above. Now we know that visible light is only a tiny fraction of the whole spectrum. We can no longer be sure of anything. So we need not fight against somebody's views nor die for our own convictions.
