called directional.
Moreover, "bad" genes are often connected to "desirable genes" (pleitropy). Sickle cell anemia protects certain African tribes against malaria. This is called "diversifying or disruptive natural selection". Artificial selection can thus fast deteriorate into adverse selection due to ignorance.
Modern eugenics relies on statistics. It is no longer concerned with causes - but with phenomena and the likely effects of intervention. If the adverse traits of off-spring and parents are strongly correlated - then preventing parents with certain undesirable qualities from multiplying will surely reduce the incidence of said dispositions in the general population. Yet, correlation does not necessarily imply causation. The manipulation of one parameter of the correlation does not inevitably alter it - or the incidence of the outcome.
Eugenicists often hark back to wisdom garnered by generations of breeders and farmers. But the unequivocal lesson of thousands of years of artificial selection is that cross-breeding (hybridization) - even of two lines of inferior genetic stock - yields valuable genotypes. Inter-marriage between races, groups in the population, ethnic groups, and clans is thus bound to improve the species' chances of survival more than any eugenic scheme.
The Myth of the Right to Life
By: Dr. Sam Vaknin
I. The Right to Life
Generations of malleable Israeli children are brought up on the story of the misnamed Jewish settlement Tel-Hai ("Mount of Life"), Israel's Alamo. There, among the picturesque valleys of the Galilee, a one-armed hero named Joseph Trumpeldor is said to have died, eight decades ago, from an Arab stray bullet, mumbling: "It is good to die for our country." Judaism is dubbed "A Teaching of Life" - but it would seem that the sanctity of life can and does take a back seat to some overriding values.
The right to life - at least of human beings - is a rarely questioned fundamental moral principle. In Western cultures, it is assumed to be inalienable and indivisible (i.e., monolithic). Yet, it is neither. Even if we accept the axiomatic - and therefore arbitrary - source of this right, we are still faced with intractable dilemmas. All said, the right to life may be nothing more than a cultural construct, dependent on social mores, historical contexts, and exegetic systems.
Rights - whether moral or legal - impose obligations or duties on third parties towards the right-holder. One has a right AGAINST other people and thus can prescribe to them certain obligatory behaviors and proscribe certain acts or omissions. Rights and duties are two sides of the same Janus-like ethical coin.
This duality confuses people. They often erroneously identify rights with their attendant duties or obligations, with the morally decent, or even with the morally permissible. One's rights inform other people how they MUST behave towards one - not how they SHOULD or OUGHT to act morally. Moral behavior is not dependent on the existence of a right. Obligations are.
To complicate matters further, many apparently simple and straightforward rights are amalgams of more basic moral or legal principles. To treat such rights as unities is to mistreat them.
Take the right to life. It is a compendium of no less than eight distinct rights: the right to be brought to life, the right to be born, the right to have one's life maintained, the right not to be killed, the right to have one's life saved, the right to save one's life (wrongly reduced to the right to self-defense), the right to terminate one's life, and the right to have one's life terminated.
None of these rights is self-evident, or unambiguous, or universal, or immutable, or automatically applicable. It is safe to say, therefore, that these rights are not primary as hitherto believed - but derivative.
The Right to be Brought to Life
In most moral systems - including all major religions and Western legal methodologies - it is life that gives rise to rights. The dead have rights only because of the existence of the living. Where there is no life - there are no rights. Stones have no rights (though many animists would find this statement abhorrent).
Hence the vitriolic debate about cloning which involves denuding an unfertilized egg of its nucleus. Is there life in an egg or a sperm cell?
That something exists, does not necessarily imply that it harbors life. Sand exists and it is inanimate. But what about things that exist and have the potential to develop life? No one disputes the existence of eggs and sperms - or their capacity to grow alive.
Is the potential to be alive a legitimate source of rights? Does the egg have any rights, or, at the very least, the right to be brought to life (the right to become or to be) and thus to acquire rights? The much trumpeted right to acquire life pertains to an entity which exists but is not alive - an egg. It is, therefore, an
