“Many textbooks point out that no animal has evolved wheels and cite the fact as an example of how evolution is often incapable of finding the optimal solution to an engineering problem. But it is not a good example at all. Even if nature could have evolved a moose on wheels, it surely would have opted not to. Wheels are good only in a world with roads and rails. They bog down in any terrain that is soft, slippery, steep, or uneven. Legs are better. Wheels have to roll along an unbroken supporting ridge, but legs can be placed on a series of separate footholds, an extreme example being a ladder. Legs can also be placed to minimize lurching and to step over obstacles. Even today, when it seems as if the world has become a parking lot, only about half of the earth's land is accessible to vehicles with wheels or tracks, but most of the earth's land is accessible to vehicles with feet: animals, the vehicles designed by natural selection.”

“No connection, you would agree. But things can come together in strange ways. The wood was at the center, the hub of the wheel. All wheels must have a hub. A ferris wheel has one, as the sun is the hub of the wheeling calendar. Fixed points they are, and best left undisturbed, for without them, nothing holds together. But sometimes people find this out too late.”

“A brick could be affixed to each end of an axle, for an example of transportation in a pre-wheel society.

“Roarke: You'd enjoy flying more if you'd learn the controls.Eve: I'd rather pretend I'm on the ground.Roarke: And how many vehicles have you wrecked, had blown up, or destroyed in the last, oh, two years?Eve: Think about that, then imagine it happening when I'm at the wheel at thirty thousand feet.Roarke: Good point. I'll do the flying.”

“Humans are often credited with having real foresight, in distinction to the rest of biology which does not. For example, Dawkins compares the 'blind watchmaker' of natural selection with the real human one. 'A true watchmaker has foresight: he designs his cogs and springs, and plans their interconnections, with a future purpose in his mind's eye. Natural selection . . . has no purpose in mind'.I think this distinction is wrong. There is no denying that the human watchmaker is different from the natural one. We humans, by virtue of having memes, can think about cogs, and wheels, and keeping time, in a way that animals cannot. Memes are the mind tools with which we do it. But what memetics shows us is that the processes underlying the two kinds of design are essentially the same. They are both evolutionary processes that give rise to design through selection, and in the process they produce what looks like foresight.”

“Politics is not the solution to our problems. It's only a small gear of the wheel.”
