The Bed of Procrustes was a silly old story until about three minutes ago.
Now I see it differently. It describes mental filters. Biases.
When we wander around with preconceived ideas, we only see what we are looking for. Reality is much, much larger than our pea-sized brains.
So when we approach the world with our own conceptions about The Way Things Are, we fit the world into our own mental Procrustean Bed.
