Do you group your books by predominant color of the cover and texture? Or do you group them by subject matter, wether you read them already, wether you would read them again, size, that sort of stuff? The whole idea of human "races" is kind of broken.
I have books with small print that are stupid, I have books with big colorful pictures which are smart. Selecting them by superficial criteria like that, stuff like "is the page count a multiple of 11?" is just hurting yourself.
We operate by finding patterns of large data sets and then manipulating the patterns.
That is literally how our species thinks.
Yup. And our thinking gets *better* by repeating that process. Maybe even reflecting a little, trying to find patterns in the patterns we think we see. Maybe in some dark age it was really important to trust the person who looks like you more than a tree, a lion or a person who is painted in a completely different way (I dare guess that in the times that stuff evolved biologically, differences in skin tone probably played exactly no role). But things quickly got way more complex than that. Using symbols made our thinking powerful, yes, but confusing symbols with things can also become more costly than useful real quick.
