Part 3

The Malthusian Mechanism

Limited resources lead to wars, famine, and diseases and, thus, to a decrease in human numbers. Mankind has done well to check famine, fend off disease, and staunch war. But to have done so without a commensurate policy of population control was irresponsible.

The Assimilative Mechanism

Mankind is not divorced from nature. Humanity is destined to be impacted by its choices and by the reverberations of its actions. Damage caused to the environment haunts - in a complex feedback loop - the perpetrators.

Examples:

Immoderate use of antibiotics leads to the eruption of drug-resistant strains of pathogens. A myriad types of cancer are caused by human pollution. Man is the victim of its own destructive excesses.

The Cognitive Mechanism

Humans intentionally limit the propagation of their race through family planning, abortion, and contraceptives. Genetic engineering will likely intermesh with these to produce "enhanced" or "designed" progeny to specifications.

We must stop procreating. Or, else, pray for a reduction in our numbers.

This could be achieved benignly, for instance by colonizing space, or the ocean depths - both remote and technologically unfeasible possibilities.

Yet, the alternative is cataclysmic. Unintended wars, rampant disease, and lethal famines will ultimately trim our numbers - no matter how noble our intentions and how diligent our efforts to curb them.

Is this a bad thing?

Not necessarily. To my mind, even a Malthusian resolution is preferable to the alternative of slow decay, uniform impecuniosity, and perdition in instalments - an alternative made inexorable by our collective irresponsibility and denial.

Racing Down

Eugenics and the Future of the Human Species

By: Dr. Sam Vaknin

"It is clear that modern medicine has created a serious dilemma ... In the past, there were many children who never survived - they succumbed to various diseases ... But in a sense modern medicine has put natural selection out of commission. Something that has helped one individual over a serious illness can in the long run contribute to weakening the resistance of the whole human race to certain diseases. If we pay absolutely no attention to what is called hereditary hygiene, we could find ourselves facing a degeneration of the human race. Mankind's hereditary potential for resisting serious disease will be weakened."

(Jostein Gaarder in "Sophie's World", a bestselling philosophy textbook for adolescents published in Oslo, Norway, in 1991 and, afterwards, throughout the world, having been translated to dozens of languages)

The Nazis regarded the murder of the feeble-minded and the mentally insane - intended to purify the race and maintain hereditary hygiene - as a form of euthanasia.

German doctors were enthusiastic proponents of an eugenics movements rooted in 19th century social Darwinism. Luke Gormally writes, in his essay "Walton, Davies, and Boyd" (published in "Euthanasia Examined - Ethical, Clinical, and Legal Perspectives", ed. John Keown, Cambridge University Press, 1995):

"When the jurist Karl Binding and the psychiatrist Alfred Hoche published their tract The Permission to Destroy Life that is Not Worth Living in 1920 ... their motive was to rid society of the 'human ballast and enormous economic burden' of care for the mentally ill, the handicapped, retarded and deformed children, and the incurably ill. But the reason they invoked to justify the killing of human beings who fell into these categories was that the lives of such human beings were 'not worth living', were 'devoid of value'"

It is this association with the hideous Nazi regime that gave eugenics - a term coined by a relative of Charles Darwin, Sir Francis Galton, in 1883 - its bad name. Richard Lynn, of the University of Ulster of North Ireland, thinks that this recoil resulted in "Dysgenics - the genetic deterioration of modern (human) population", as the title of his controversial tome puts it.

The crux of the argument for eugenics is that a host of technological, cultural, and social developments conspired to give rise to negative selection of the weakest, least intelligent, sickest, the habitually criminal, the sexually deviant, the mentally-ill, and the least adapted.

Contraception is more widely used by the affluent and the well-educated than by the destitute and dull. Birth control as practiced in places like China distorted both the sex distribution in the cities - and increased the weight of the rural population (rural couples in China are allowed to have two children rather than the urban one).

Modern medicine and the welfare state collaborate in sustaining alive individuals - mainly the mentally retarded, the mentally ill, the sick, and the genetically defective - who would otherwise have been culled by natural selection to the betterment of the entire species.

Eugenics may be based on a literal understanding of Darwin's metaphor.

The 2002 edition of the Encyclopedia Britannica has this to say:

"Darwin's description of the process of natural selection as the survival of the fittest in the struggle for life is a metaphor. "Struggle" does not necessarily mean contention, strife, or combat; "survival" does not mean that ravages of death are needed to make the selection effective; and "fittest" is virtually never a single optimal genotype but rather an array of genotypes that collectively enhance population survival rather than extinction. All these considerations are most apposite to consideration of natural selection in humans. Decreasing infant and childhood mortality rates do not necessarily mean that natural selection in the human species no longer operates. Theoretically, natural selection could be very effective if all the children born reached maturity.
