To add to and clarify the comments that others have made, as well as Dawkins’ original contention–the harm of astrology, naturopathic medicine, et cetera is that they adopt the language and terminology of science but are not themselves based upon science or fact. Casually reading and enjoying the horoscope column in the Sunday paper is one thing (I prefer The Onion for all of my astrology needs), but when you are making descions about the fate of the free world you should probably be consulting more, uh, astute sources than your wife’s soothsayer. (Robert Heinlein hit that one on the head, at least.)
When you get into a field like medicine the damage becomes even more pronounced. “Naturopathic medicine”–and in particular the snake-oil pseudoscience of homeopathy and allopathic medicine–serves only to provide a nonsense alternative to effective, if less hyped standard medical treatments treatments. The alleged mechanisms behind such treatments make less sense than the four bodily humours, and the result is often that patients eschew proven treatments with limited (but realistic) claims in favor of the miracle quack nostrums to their eventual ruin. How many breast cancer patients who could have survived via surgery and light chemotherapy have instead succombed while persuing a program of Laetrile treatment?
This isn’t to say that Western pharmacological-based medicine is the end-all, be-all of medicine; as the field develops it is often discovered that some standard treatments are little more effective than placebo, or that illnesses thought to have one simple cause are in fact the result of several unsuspected influences. Indeed, it is the key facet of the scientific method that any theory, no matter how established, is still subject to challenge and disproof. Nor can it be said that there is nothing to be gained from investigating traditional or osteopathic treatments; new drugs are often discovered in (and improved from) folk remedies, and osteopaths, acupuncturists, and other “traditional healers” have long known what is only now becoming apparent to Western medical science, namely that accurate and comprehensive diagnosis requires a holistic approach to pathology rather than just zeroing in and treating the obvious symptoms. But these are lessons to be winnowed out from the chaff of superstition.
From that perspective, these “crazy things” aren’t just harmless diversions but instead insidious mistruths which detract from the ability of people to make accurate observation and critical assessment of the world around them. If you believe that light bulbs are illluminated by faerie magicks then you aren’t going to bother learning about electricity, and when the fuse blows out all of the praying and sacrificing to the faerie king isn’t going to bring the lights back. As fighting against ignorance and learning to appreciate the beauty in knowledge rather than worshiping a veil of mysticism is the key theme of the book (the title of the book is a reference to Keat’s criticism of Isaac Newton shattering the elegance of a rainbow by describing the components that make it), this essay was particularly adroit, certainly moreso than some others included.
Aside from his positions in his technical field of study (evolutionary zoology), I tend to agree with Dawkins philosophically on most counts, including his advocacy of atheism and criticism of unfounded mysticism as an obfusacatory tactic by those who advocate positions that they cannot validate. But I have to admit that he often overreaches–and in a manner that is obnoxiously polemical–when he tries to conflate his writings on evolution with his position on religion, and as a result weakens both arguments. As a scientist and champion of Ronald Fisher’s study of quanatitive genetics and George C. Williams theory of gene-centricity kin selection (as well as making valuable contributions of his own in ethology) he’s done very valuable work, and his popular writings (The Selfish Gene, The Extended Phenotype, The Blind Watchmaker) have served to make modern evolutionary theory accessible to non-technical readers (even if they have been rampantly misinterpreted in their themes and appropriately questioned in some details). As a philosopher and social theorist, however, he comes across as being distinctly amateurish; his contemporary and competitor in science popularization, Stephen J. Gould, was actually much superior in this regard and made the effort to present the viewpoints of those he stringently disagreed with not as deluded or ignorant but rather based upon a different body of knowledge and understanding of the natural world.
In the case of the article quoted from the OP, it seems that Dawkins was attempting–rather lamely and unsuccessfully, in my personal literary opinion–to engage in social satire in the vein of Johnathon Swift. One can scarcely read past the second paragraph without coming to the realization that he’s making an analogy, and one that is rather old hat for all of that. I don’t think he’s wrong–he makes some valid points in the article–but the writing isn’t particularly effective as satire and could be taken by many as being simply in bad taste, which is nearly always the response to ineffective humor.
