Medical technology: difficult questions ahead
The poignant case of baby MB
(Judge backs parents in refusing withdrawal of baby's
life support)
highlights the growing moral, ethical and legal questions posed by the
increasing ability of medical technology to sustain humans whose
natural organs can no longer function unaided.
But an even bigger dilemma looms on the horizon: as nanoscience
combines with medical technology to manipulate and even replace brain
tissue, what will be the legal status of part-human, part-silicon
hybrids that are able to exercise free will? Will such entities have
'human' rights and legal liability? At what point will it be possible
to declare patients clinically dead so that death certificates --
essential legal instruments in society -- may be issued?
The answers to these and similar questions that are already arising
will depend on our definition of human consciousness; an area in which
our knowledge is still next to nothing.

We have become a sex-obsessed society
So it has come to this. Our children can no longer visit supermarket
toilets without fear of attack by sexual predators
(Girl aged 11 raped in supermarket, 07 Mar 06).
The estimated age of the suspect is telling - just 16. If correct this
tragedy will be the latest in a string of increasingly violent sex
crimes by youngsters that include brazen attacks on teachers in the
classroom. But how much have we, adults, contributed to this appalling
state of affairs?
We have become a sex-obsessed society with gratuitous images, foul
language and innuendo pervading every aspect of life. A pleasurable act
bequeathed to us by nature for the purposes of procreation has become
the prime definition of our culture. Sex is healthy. Sexual
obsession is perverse. My wife and I (hardly religious prudes) once
stared in disbelief at a huge billboard along London's North Circular
displaying a near-nude female in cowboy boots and hat selling -- wait
for it -- office accommodation!
Advertisements during last night's screening of Malcolm X (a Black
Muslim icon) on ITV4 were exclusively for sex and singles chat lines
with the usual suggestive images. Sex 'sells', hence its cynical
commercial over-exploitation in a society that has lost all moral
restraint. No wonder
some Muslims in Britain and groups like
Christian Exodus in the US wish to live in separate areas
governed by ecclesiastical law.
It is disingenuous and hypocritical to contend (as apologists do) that
our glamourisation of sex has nothing to do with the corruption of our
young. Until recently the UK had the highest number of under-age
pregnancies per head of population in Europe. No amount of sex
education will reverse the trend significantly unless we also adopt
more responsible attitudes to sex in public. And that means curbing the
urge to indulge in exhibitionist practices like 'dogging' -- having sex
in public car parks -- made fashionable by celebrities. Ironically,
even as we wallow in eroticism, birth rates are falling in many
European states (immigrants excepted). Perhaps the strain of permanent
arousal is affecting our production of the necessary gametes!
Historians tell us that sexual depravity contributed to the downfall of
ancient Greek and Roman civilisations. If we do not act to return sex
to the confines of private relationships where it properly belongs, we
may live to see our post-modern, secular societies fall to religious
fundamentalists.

Evolution and ID: The controversy continues
Rupert Cornwell's report in
The Independent (Feb 21) on the continuing
controversy in the US over Evolution and ID (Intelligent Design) shows
how misunderstood and confused the issues have become.
Evolution is accepted as fact within the scientific community for
convenience; not because it has been conclusively proven.
Investigation continues into the origins of life
and macroevolution (emergence of an entirely new species from
another). Almost 150 years after Darwin, no fossils in transition
between species -- except for
notorious forgeries -- have ever been found. But
there is plenty of evidence for microevolution (development of new
features within species that aid survival).
Christian fundamentalists take the Bible assertion that God created man
in his own image literally. They therefore vehemently oppose any
teaching that we 'evolved from monkeys' since this by inference reduces
God to a bestial concept. Legal battles over evolution in US schools
go back to 1925 when
John Scopes was fined $100 for violating a
Tennessee law that forbade any teaching 'that man has descended from a
lower order of animals'. Since then fundamentalists have seized on any
scientific proposal that appears to contradict evolution.
Some scientists (hardly crazed fundamentalists) believe the
evidence
suggests that intelligent causes exist and these can be empirically
detected -- hence ID. Supporting pillars other than the
irreducible complexity of life forms include the
anomalous structure of water (without which no
life can exist),
anthropic coincidences
and the remarkable
Fibonacci ratio. The cumulative evidence has persuaded distinguished
former sceptics like physicist Freeman Dyson and philosopher Antony
Flew.
Contrary to media reports ID is not an 'anti-evolution movement'.
It just happens to be the latest tool employed by
fundamentalists in their long campaign against the teaching of
evolution as a scientific fact. It is worth remembering that when
Darwin presented his theory of evolution as the origin of species, many
bitter sceptics were scientists while some enthusiastic supporters were
Christian theologians and writers that saw evolution as God's plan
unfolding over geological time.
As Lehigh University Professor of Biochemistry Michael J. Behe reminds
colleagues:
"Science is not a game in which arbitrary rules are used to decide what
explanations are to be permitted. Rather, it is an effort to make true
statements about physical reality."
Rather than the current hysterical reaction that is achieving
little more than sensational press reports, the scientific
establishment should reclaim ID from religious fundamentalists and
support research to determine the origin of the intelligence in nature
that is becoming increasingly hard to ignore.

Feeding the Mind
At the start of Lent last year
I examined the practice of periodic
fasting that is encouraged by some religions and the origin of the
preceding bacchanalia. I have since learnt that the term 'Carnival' for
the excesses over Mardi Gras derives from 'Carne' (meat) and 'Vale'
(goodbye). Thus, observers are literally waving goodbye to meat and
other things of the flesh immediately before abstinence for 40 days and
nights.
It is interesting how many secular people also make an effort at
self-denial over Lent. Alison Steed highlights some financial benefits
for those willing to give up a few luxuries
(Daily Telegraph, 25 Feb 06). Ed Caesar suggests an
environment-friendly action plan for self and the public
(Independent, 01 March 06). The latter
includes giving up 'rushing' and 'working through lunch'. Caesar
quotes A.C. Grayling: "A great deal of possibility, of new ideas, is
lost by rushing." And "We've forgotten what's meant by 'recreation' . .
. It means to reinvigorate [re-create] yourself, to get your powers
back up again, and to feed one's mind as well as one's body."
Increasingly the mindless frenzy of modern society is depriving us of
the space and ability to think rationally and productively. Our desire
for simple, instant explanations and solutions is leaving us open to
manipulation by unscrupulous charlatans of all persuasions. Human
agenda is in danger of being reduced to knee-jerk reactions to
spoon-fed media propaganda (especially on television), spun at the
behest of power-hungry politicians, religious extremists and greedy
corporatists among others.
As Rene Descartes said, "Corgito ergo sum [I think, therefore I am]".
Mental inactivity and a diet of junk ideas lead to degeneration of the
mind just as lack of physical exercise and a diet of junk food harm our
physical body. It is frightening that we appear to be forgetting the
real lesson of Hitler: how easy it is to induce and harness herd
mentality for evil pursuits in a society that has lost the capacity for
independent thought.
Whether or not one is religious, it is a good idea to indulge in
periods of quiet contemplation away from the hubbub of life. Charles
and John Wesley (founders of Methodism) recounted this warning by their
mother: "Anything that gives the body power over the mind is an evil
thing."
We need to feed our mind regularly with the right nutrition so
it can flourish and control negative physical impulses.
