The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two?

Interesting. I discovered for myself that by cupping my fingers in such a way as to present a small aperature to my eye I would see distant objects more clearly. Like a natural monocular. Is that what he is do8ng here?
A common old device for the optically challenged: a patch with many pinholes. Limiting the path to something approaching a single ray is the same as increasing the f number to approach infinity. Any defect in the optical train is therefore negated. The depth of field is therefore amazing.
