Jon Hubbard, a Republican member of the Arkansas House of Representatives, has a book, titled "Letters to the Editor: Confessions of a Frustrated Conservative." Among its statements for which Hubbard has been criticized and disavowed by the Republican Party is, "The institution of slavery that the black race has long believed to be an abomination upon its people may actually have been a blessing in disguise. The blacks who could endure those conditions and circumstances would someday be rewarded with citizenship in the greatest nation ever established upon the face of the Earth."

Hubbard's observation reminded me of my 1972 job interview at the University of Massachusetts. During a reception, one of the Marxist professors asked me what I thought about the relationship between capitalism and slavery. My response was that slavery has existed everywhere in the world, under every political and economic system, and was by no means unique to capitalism or the United States. Perturbed by my response, he asked me what my feelings were about the enslavement of my ancestors. I answered that slavery is a despicable violation of human rights but that the enslavement of my ancestors is history, and one of the immutable facts of history is that nothing can be done to change it.

The matter could have been left there, but I volunteered that today's American blacks have benefited enormously from the horrible suffering of our ancestors. Why? I said the standard of living and personal liberty of black Americans are better than what blacks living anywhere in Africa have. I then asked the professor what it was that explained how tens of millions of blacks came to be born in the US instead of Africa. He wouldn't answer, but an answer other than slavery would have been sheer idiocy. I attempted to assuage the professor's and his colleagues' shock by explaining to them that to morally condemn a practice such as slavery does not require one to also deny its effects.

My yet-to-be-learned lesson -- and perhaps that of Rep. Hubbard -- is that there are certain topics or arguments that one should not bring up in the presence of children or those with little understanding. Both might see that explaining a phenomenon is the same as giving it moral sanction or justification. It's as if one's explanation that the independent influence of gravity on a falling object is to cause it to accelerate at 32 feet per second per second could be interpreted as giving moral sanction and justification to gravity.

Slavery is widely misunderstood, and as such has been a tool for hustlers and demagogues. Slavery has been part of the human condition throughout recorded history and everywhere on the globe. Romans enslaved other Europeans; Greeks enslaved other Greeks; Asians enslaved Asians; Africans enslaved Africans; and in the New World, Aztecs enslaved Aztecs and other native groups. Even the word slave is derived from the fact that Slavic people were among the early European slaves.

Though racism has been used to justify slavery, the origins of slavery had little to do with racism. In recent history, the major slave traders and slave owners have been Arabs, who enslaved Europeans, black Africans and Asians. A unique aspect of slavery in the Western world was the moral outrage against it, which began to emerge in the 18th century and led to massive efforts to eliminate it. It was Britain's military might and the sight of the Union Jack on the high seas that ultimately put an end to the slave trade.

Unfortunately, the facts about slavery are not the lessons taught in our schools and colleges. The gross misrepresentation and suggestion in textbooks and lectures is that slavery was a uniquely American practice done by racist white people to black people. Despite abundant historical evidence, youngsters are taught nothing about how the Founding Fathers quarreled, debated and agonized over the slave issue.
