Eh. To me it looks like the authors extends "lines-as-edges" explanation of why we can understand line drawings to the claim that the visual cortex works almost only on edge detection, which is obviously bunk and so easily refuted by him. Then later he shows a shillouette image we can understand even though the edges themselves are not understandable, and somehow this is supposed to be evidence against lines as edges…
The word is spelled "silhouette".

#172This is wrong, as humans have been drawing and viewing art for tens of thousands of years. Also, for other animals, a form of edge detection is present in for example the tiger paw mark that a tiger leaves on the bark of a tree to mark territory, or simply paw/foot marks on the ground.

Surely if you're upscaling pixel art you're loosing information when you create gradients between pixels. It doesn't seem to me that your metric of information loss was ideal.
Conservation is not just about preserving info, it's also about not adding information that's not here. If you upscale without those gradients (effectively sharpening to the max with nearest neighbor extrapolation) you introduce high frequencies that could not exist in the original data. You've created new information out of nowhere. But of course you're correct that in this case it may be the desirable outcome. I st…
History is sort of inherently rewritten. Memories are (very!) imperfect and even without realizing it we interpret events through our individual biases. Maybe the more precise concern is the increasing _willful_ departure from reality, but we do that naturally too, overlooking parts of reality that would be intolerable if they were always in our face.

It's hard to think of any concrete examples but I will set the scene as best I can and recommend listen to some of the 6 or 7 hour audiobooks narrated by Jonathan Cecil. I just went searching through a bunch of quote lists to try to find examples. I grabbed some just to show the breadth of metaphors and analogs used. What I think I realized is that some of the best examples are probably descriptions of the scenes. I'…
Thank you very much for finding these! I find it surprising that I remember these quotes from the 90s Hugh Laurie and Steven Fry television adaptation 'Jeeves and Wooster' - few TV programmes are faithful enough to their original book to include the dialogue verbatim!
I once tried to read him and found it difficult but the audio books ended being a good listen and available on YouTube.
What the books seem to reveal is just how central Wodehouse is to modern comedy. There are obvious Wodehouse references in Seinfeld. Such the surname VanDelay.
