Nasty, Brutish, and Tall

So how much has mankind benefitted from economic progress? Less than we might like to think. The invention of agriculture seems to have triggered a general decline in human health and loss of four inches or so in stature, probably due mainly to an inferior diet, but also perhaps to the more arduous nature of agricultural existence. Domestication of animals brought in a flood of new diseases, and greater population density facilitated epidemic spread. The general decline in stature didn't really turn around until the twentieth century.

For most of humanity, progress has usually been a bummer. The bad effects can be traced to the fact that economic "progress" triggers increases in population until Malthusian effects grind us down. Because we were originally were adapted to Darwinian competition in a much different world, we are not well suited for either the modern diet or lifestyle.

The only known or plausible way to escape the Malthusian trap is limitation of population. For the first time in human history we have good ways to do this, and much of the world has chosen to do so.

Prehistoric life was indeed nasty and brutish, but humans were well adapted to it. It took a thousand centuries, but a better way is now possible.

Anti-Libertarian: re-post

The most pointed critique of social security and liberalism in general is the libertarian critique. The problem with libertarians, for a liberal, is that we have too much in common. We both believe in individual rights, tolerance of individual differences, and dislike government prescription of religion. The basic difference, it seems to me, is the different answers we give to Cain's (with thanks to the Captain - my original version had the corpse asking the question!) famous question: "Am I my brother's keeper?" That's not really my basic bitch against the libertarians though. My real complaint is the same as my complaint against most religion - its premise is a fraud. For those who can't stand to wait for the punchline, I believe that trying to implement libertarian principles leads to tyranny or social disintegration. Demonstrating that takes some historical (and pre-historical) context. For all but the last 15,000 or so of the 100,000 years the human spec...

Uneasy Lies The Head

Uneasy lies the head that wears a crown ........... Shakespeare Henry IV, Part II. So it is with us and our slightly distant primate cousins , so it seems. A 9-year study of wild baboons in Kenya by Princeton University and the Institute of Primate Research may turn conventional assumptions of alphas males upside down. The study found that alpha males have high testosterone levels, which allows them to dominate other baboons, get access to more food, and attract better mates. This is expected. Surprisingly, though, the alpha males also have high levels of stress hormone glucocorticoid, which scientists measured from their feces samples. In fact, the stress of alpha baboons was on par with low-ranking baboons. The convention wisdom is that access to food and females provides life security and thus less stress for dominant males. Conversely, weak males who are constantly threatened by starvation and physical violence from stronger males are thought to be more stressed. The st...

We Call it Soccer

The US played its best, and maybe only good game of World Cup, but lost thanks to brilliant goalkeeping by the Swedish keeper and the bizarre method soccer uses to settle ties when three US stars could not put the ball on frame from the 12 yard spot.  At the end it came down to a blocked shot that spun in by maybe a couple of centimeters. Well, that's football - too much like life.   Which brings me to a modest proposal.  Replace the thirty minute overtimes with as many 7-player 15 minute periods as needed to settle it.  Scoring should be much easier with fewer players.
