Perceptive aberration™

Preamble:
When I was studying optics we learnt about optical aberrations, in particular one called ‘spherical aberration’.

This is where the light rays passing through an albeit perfectly spherical concave lens do not all converge onto a solitary focal point as would be intuitive. Instead the light rays further out from the optical centre of the lens increasingly converge to differing points. Basically this is due to the differing thickness of the lens from its centre to its periphery.

It is this scientific phenomena which is employed in the the pinhole camera a simple device even children can make and experiment with and which captures only those light rays which are central and eliminates those in the periphery, thus providing a clear image on a back plate, even without even a lens.

A similar experience of this affect can be noticed during bright sunlight where one’s distance vision appears to improve as your pupils tightly constrict. Conversely night vision is worse as the pupils dilate to allow more light in but in doing so permit the spherical aberration effect.

Context of this forum:
We see a similar effect in this forum where certain posters choose to only look through their metaphorical pinhole cameras at the world and indeed other people’s beliefs. To them the image they see is clear with no aberrations and so their belief that their perception of reality is correct. In fact what has happened is like the peripheral light rays the other ideas, concepts, principles etc have simply been excluded so as to not blur the focal point.

I really like this analogy and I try to apply to to my own beliefs and processing of other people’s ideas.

It IS a nice analogy, though. In fact, I wish I'd thought of it myself.

Simplifying complex problems invariably leads to this kind of error, with its attendant lack of peripheral vision.

Once again appearing in a thread merely to spread your hate.

You have proven yourself worthless long ago.

Dive seems to be recovering a bit but the rest of the group are totally worthless.
