The feeling of pity is not just anthropomorphizing. It is also metaphorical. We talk about people whose understanding only allows them to cast issues in black and white. Seeing shades of gray is weak to them because they see everything that is neither black nor white as blurring the lines, tainting the pure, and creating a shapeless, muddly mess of the world. But what they see as shades of gray is actually color to a complex mind. Yellow is not just a darker white, it has a personality distinct from a similar tone of blue or pink. All three colors could be photographed to look exactly the same gray on black and white film, but they are so completely different to the human eye that a child would not confuse them. I still remember the amazement I felt on seeing my first big box of 64 Crayola Crayons. Just looking at them was a joy.
People who scoff at middle-of-the road ethics, who mock social or educational initiatives, who defend authority and despise rebellion are people who have formed a clear idea of right and wrong. Their own lives are shaped by lines in black and white. Creative vision, situational ethics, questioning authority: these introduce variables into that picture and mess it up with grays. Such people have no 'cones' to see the color. Or more aptly, since we are all human, their 'cones' have either atrophied from disuse, or the light is too dim for them to function. (Cones need a lot of light, which is why at night, all cats are gray.) It isn't just conformity or closed-mindedness that keeps these people resistant to complex ideas. Their mental 'senses' are presenting them with a clear message, and the evidence that is so glaring to the reformers is as invisible to them as yellow to my dog.
Humans are disgusted when a dog smells shit. We laugh uncomfortably and pull away. We cannot accept that the dog loves the smell of rot or decay because our senses tell us shit is bad. No amount of logical argument will make us encourage shit-sniffing. Between species, there can be no reconciliation. Between humans, the organs of understanding are not missing. They are undeveloped. Framing what you can in black and white reduces complexity and does not solve the problem. It just causes more atrophying. Light, more light is needed, until the 'cones' kick in and reveal the beauty of complexity that makes it worth the price.
