David Lester, a psychology professor at Richard Stockton College in New Jersey, has likely thought about suicide longer, harder, and from more angles than any other human. In more than twenty-five-hundred academic publications, he has explored the relationship between suicide and, among other things, alcohol, anger, antidepressants, astrological signs, biochemistry, blood type, body type, depression, drug abuse, gun control, happiness, holidays, Internet use, IQ, mental illness, migraines, the moon, music, national-anthem lyrics, personality type, sexuality, smoking, spirituality, TV watching, and wide-open spaces. Has all this study led Lester to some grand unified theory of suicide? Hardly. So far he has one compelling notion. It’s what might be called the “no one left to blame” theory of suicide. While one might expect that suicide is highest among people whose lives are the hardest, research by Lester and others suggests the opposite: suicide is more common among people with a higher quality of life. “If you’re unhappy and you have something to blame your unhappiness on—if it’s the government, or the economy, or something—then that kind of immunizes you against committing suicide,” he says. “It’s when you have no external cause to blame for your unhappiness that suicide becomes more likely. I’ve used this idea to explain why African-Americans have lower suicide rates, why blind people whose sight is restored often become suicidal, and why adolescent suicide rates often rise as their quality of life gets better.
Despite widespread misconceptions in the United States today that the institution of slavery was based on race, for most of the thousands of years in which slavery existed around the world, it was based on whoever was vulnerable to enslavement and within striking distance. Thus Europeans enslaved other Europeans, just as Asians enslaved other Asians and Africans enslaved other Africans, while Polynesians enslaved other Polynesians and the indigenous peoples of the Western Hemisphere enslaved other indigenous peoples of the Western Hemisphere. The very word “slave" derived from the word for Slavs, who were enslaved by fellow Europeans for centuries before Africans began to be brought in chains to the Western Hemisphere. Africans were not singled out by a race for ownership by Europeans, they were resorted to after the rise of nation-states with armies and navies in other parts of the world which reduced the number of places that could be raided for slaves without great costs and risks. Slave-raiding continued in Africa, primarily by Africans enslaving other Africans and then, in West Africa, selling some of their slaves to whites to take to the Western Hemisphere. Meanwhile, the growing range of ships and the growing wealth of nations eventually made economically feasible the transportation of vast numbers of slaves from one continent to another, creating racial differences between the enslaved and their owners as a dominant pattern in the Western Hemisphere. Such a pattern was by no means limited to Europeans owning non-Europeans, however. There were many examples of the reverse, quite aside from vast regions of the earth where neither the slaves nor their owners were either black or white.
