Evolution, Science, and Urban Legends

Superstitions of the Age

The current age thinks itself the best and the brightest. This is an effect, in part, of the reigning paradigm of the current scientific community: evolutionism. This scientific meta-theory propounds that things develop by natural order and law: that is, they evolve to higher and higher planes of existence, from the simple to the more complex and advanced.  

Under the influence of evolutionism, each generation tends to consider itself superior and more advanced than those that have gone before. One upshot is the denigration of history to irrelevance. Why study primitives--except to set a backdrop for our comparatively advanced and sophisticated state?

One manifestation of this self-claimed superiority is medical science. Pop-medicine regales us with accounts of how superstitious and primitive the medical knowledge and treatments of former generations was. Implication: we are so much better and smarter now. One example of a medical procedure once widely practised in the West is bleeding. There are many others.  "How stupid and ignorant those doctors and medical scientists were," is the overriding discourse.

Conveniently, we overlook the embarrassing implication that generations to come will look back at us and likewise chortle with amusement at the ignorance and stupidity of the medical profession at the "turn of the century". This is not to deny that knowledge via the hard sciences does increase and grow. There is a very important sense in which we now know far more than the "bleeders". The Christian attributes this to the coming of the Kingdom of God upon earth, as man fulfils the commands of subduing the earth and making it bring forth and bud, on the one hand, and makes disciples of Christ of every nation, on the other. This is gradual, developmental process is the fruit of God's unfolding human history for His glory and the blessing of His people. It is not the result of the "law" of randomness, as the evolutionist propounds.

The Christian also knows through rigorous historical research that cultures and ages do not necessarily retain the knowledge they acquire. Things known now can be lost to future generations, through wars, famines, plagues, earthquakes and other calamities. It can also result from civilisations crumbling from with--partially at times as a result of scientific and technological error. The Roman's proclivity to use lead pipes almost certainly contributed to the decline of that civilisation.

This raises the possibility that current prevailing medical consensuses may turn out to be profoundly ignorant and damaging to society. Take for example diet. We are threatened, we are told, by a plague of obesity. A new term has entered the lexicon: morbidly obese. Nutritionists, funded by the state, lecture us on what we should eat, and not eat--to escape the scourge. But obesity is just the latest food-related plague. Prior to that it was heart disease.

But what if the dietary preventatives for heart disease (high carb, low-fat diets) actually helped produce an epidemic of obesity? One gets an inkling that future generations will look back at us and conclude that we really were an ignorant lot.

One risk we are very clear about: when science gets married to government campaigns or programmes, the first thing to fly out the window is scientific rigour. The thing is that rigorous scientific research, particularly when dealing with human beings, is inevitably tenuous. It has to end up talking about probabilities and possibilities. Moreover, much current research is statistically based, trying to establish correlations and, from there, causality. For instance: 62% of people with bigger than average eye teeth contract gangrene in rest homes. Ergo, eye teeth size is a likely causal factor for gangrene.

Such research methodology, unless rigorously constrained, is readily subject to fallacious reasoning. But governments require certainty for public health programmes. "Large eye teeth are a danger: get your dentist to reduce their size."  Actually, this rapidly translates into state funding of eye-teeth reduction procedures.  This food is "bad"; that food is "good". Don't do this; do that. When government, who pay, require emphatic certainty, scientists readily comply. But rigour and integrity have long since flown out the window. The upshot: urban myths substitute for effective cures.

When all this takes place within the prevailing discourse of evolutionism, flattering the age with the idea that we are the best and the brightest thus far, superstition and easy credulity can rapidly become the order of the day.
