Fluffy Cats to Fat Brains

You have seen cranky cats--they can swell to a seemingly larger animal by bristling their fur. This is a similar effect to dogs finding something elevated to mark. The position on the fire hydrant tells the message RECIPIENT the important data--how big the dog is who shares their neighborhood. Think what critical tinformation that is--kind of like the reason you laugh harder at your boss's jokes.The point here is the advantage size offers in a world of constantly changing chemical flux.

Which makes me wonder if the motive for building the pyramids was similarly biological and motivated. What if the drive that ordered the monumental architecture was like a cat expanding in physical size. Of course, one motive does not rule out other explanations--such either/or logic is fundamental to ordinary mentation (I mean since there is explanation A for the motive of building the pyramids, that rules out explanation B being potent) and a hindrance to considering anything beyond the actual rearranging of the external world. The examples of such rearrangement in this paragraph are not the useful scientifically needed reordering that are obviously useful--like windmills. The very obscureness, of the reason for the size and shape of the pyramids stresses the necessity to look elsewhere for an explanation of their building. My suggestion is that monumental buildings are an attempt by men to fluff up themselves. And it should work, imagine an invading army encountering the pyramids for the first time. Not Napoleon, but the very first time, wouldn't the leader of the invading army think, "what have I gotten myself into?"

And what if---most of man's thinking, most of human words, words like 'Yale' (to use one of Jan Cox's favorite examples) are similarly the result of a need for mortal man to fluff up himself against a reality of the unknown. Perhaps words which do not refer to the external world have a purpose that is hormonal rather than denotative. Only people are unaware of their motives and the reality of the cognitive import of what they are saying.
