Book summary “A Devil's Chaplain”: summary

Introduction

You often navigate a world saturated with unearned deference to faith, religious dogmas, and pervasive pseudoscience. You face the constant challenge of distinguishing rigorous empirical evidence from comforting cultural delusions. Richard Dawkins offers a robust defense of scientific truth, evolutionary biology, and critical thinking in his collection of essays.

Science is the ultimate tool for truth, standing against the infectious mind viruses of religion and pseudoscience through rigorous evidence and Universal Darwinism.

This summary explores the foundational principles of scientific skepticism and empirical testing. You will examine the mechanics of Universal Darwinism and digital genetics across biological systems. You will also analyze how cultural ideas replicate through memetics and why organized religion demands unquestioning obedience.

What makes scientific evidence superior to postmodern relativism? How do genes and memes shape human behavior? Why do religious dogmas persist despite lacking empirical support?

1. Science and Sensibility

Science relies on rigorous empirical evidence and testability, whereas postmodernism and alternative practices rely on meaningless jargon and unearned deference. You must look past fashionable intellectual impostures to value genuine empirical thought.

Some prominent postmodern and psychoanalytic intellectuals use scientific and mathematical terminology in a meaningless and fraudulent way to project false profundity.

Alan Sokal and Jean Bricmont analyzed various fashionable thinkers who invoke physics, mathematics, and chaos theory completely out of context and with total disregard for their real meanings. They substituted jargon and word-games for genuine thought.

Jacques Lacan attempted to prove an algebraic equation using square roots of minus one in a way that is pure gibberish. Luce Irigaray argued that Einstein's mass-energy equivalence formula is a sexed equation that privileges the speed of light over other speeds.

Postmodern Impostures

Computer algorithms can automatically generate endless streams of grammatically correct postmodern nonsense that are indistinguishable from real texts by famous theorists.

Andrew Bulhak created a computer program called the Postmodernism Generator that spontaneously produces complex, unique academic papers complete with numbered endnotes using faultless grammatical principles.

The program generated an article called Capitalist theory and the subtextual paradigm of context attributed to authors from the Department of English at Cambridge University. The randomly generated article produced by the program reached 6000-words in length.

The Sokal Hoax

A physicist successfully exposed the lack of academic rigor in cultural studies journals by publishing a completely bogus, jargon-filled paper that passed peer review.

Alan Sokal submitted a intentionally nonsensical paper packed with postmodern buzzwords and scientific howlers to the American journal Social Text. The editors accepted and published it because its ideological stance conformed to their own beliefs, failing to catch the absurd fake science.

In 1996, Alan Sokal submitted the paper titled Transgressing the Boundaries: towards a transformative hermeneutics of quantum gravity to Social Text. It was accepted and later revealed as unadulterated nonsense, which won him the Ig Nobel Prize for literature.

Universal Darwinism

Biology becomes a mere collection of disconnected facts unless it is taught through the unifying lens of evolution. Rigid exam syllabuses often relegate evolution to a brief mention at the end of courses, forcing teachers into rote learning. However, without evolutionary theory, you cannot understand why biological phenomena exist.

Frederick William Sanderson transformed a struggling school into a powerhouse of science and engineering by rejecting rote examinations in favor of freedom, cooperation, and practical discovery. As headmaster of Oundle from 1892 to 1922, Sanderson left laboratories and workshops unlocked, encouraged independent student research, focused heavily on average or struggling pupils, and integrated practical making with intellectual inquiry. Student numbers grew from 100 to 500 over thirty years during his 1857 to 1922 lifespan.

When a student accidentally damaged a surface plate by using it as an anvil, Sanderson's punishment was Oundelian. The student had to study the manufacture and use of surface plates and present a report.

Richard Dawkins illustrated the vastness of evolutionary time by comparing a history book written at one century per page to a slender paperback for a Young Earth creationist view versus a bookshelf ten miles long for actual scientific history.

Darwinian natural selection is not merely a localized phenomenon for Earth's biology, but a fundamental universal principle wherever life may exist. In 1982, the author introduced the concept of Universal Darwinism at a Cambridge conference commemorating the centenary of Darwin's death to denote that replication, mutation, and selection are foundational mechanisms inherent to life itself across the universe. The term was further discussed in 1991 at the second Man and Beast symposium in Washington DC, extending Darwin's insights far beyond standard terrestrial biology.

2. Darwinism and Evolutionary Theory

Universal Darwinism explains adaptation and selection across biology, while sexual selection and genetic mechanisms govern life's complexity.

Core Darwinism defines evolution as the adaptationally nonrandom survival of small, random hereditary changes through gradual steps. Navigating the gigantic mathematical space of possible organisms requires gradualistic steps because the vast majority of genetic combinations are non-viable or dead. Searching the immediate genetic neighborhood of already viable organisms is the only way to find improved adaptations.

Universal Darwinism arguments dictate that recipe and epigenetic embryology is irreversible and cannot reverse-translate acquired traits into genes, indiscriminate inheritance of acquired traits would accumulate injuries and disease, and use-and-disuse rules are too crude to fashion intricate microscopic adaptations like eye lenses. Lamarckian inheritance of acquired characteristics fails theoretical tests because embryology is epigenetic, acquired traits are rarely improvements, and use-and-disuse rules lack fine-tuning power.

Sexual Selection

Charles Darwin and Alfred Russel Wallace disagreed sharply over sexual selection, with Wallace rejecting pure aesthetic whim in favor of utilitarian explanations. While Darwin believed that female aesthetic preference for bright colors and ornamentation could evolve purely as an arbitrary preference, Wallace insisted that advertising traits must signal utilitarian qualities like being a good provider. Helena Cronin's book The Ant and the Peacock traces these threads, classifying later theorists as Wallaceans and Darwinians. Modern Wallaceans like William Hamilton and Amotz Zahavi view these traits as honest badges of true quality such as health or parasite resistance.

R.A. Fisher provided a sound theoretical foundation for sexual selection by showing how female preference and male advertisement genes coevolve. Fisher suggested that female preference could be under genetic control and subject to natural selection just like male qualities. The interaction between selection on female preference genes and male advertisement genes drives the expansion of increasingly extravagant sexual advertisements.

Sexual selection is strictly about competition between members of the same sex for mates, differing from the broader mechanics of natural selection. Sexual selection produces adaptations for outcompeting rivals, such as fighting weapons or attraction displays. Essential reproductive organs like a penis for intromission are products of natural selection because they are needed regardless of rival competition, whereas ornamental colors on those organs are products of sexual selection.

Male vervet monkeys have a bright red penis and sky-blue scrotum used in dominance displays, which would lose their colors if rival competition were removed.

You can determine if a trait was sexually selected by testing its survival value:

• Imagine that all competitors of the same sex could be magicked away.
• Observe if the pressure for the adaptation disappears to determine if it was sexually selected.

Genetics and Human Evolution

R.A. Fisher proved that the stable sex ratio is determined by equal parental expenditure of resources on sons and daughters. Since every individual has one father and one mother, the total male contribution to posterity equals the total female contribution. If one sex is in the minority, an individual of that sex expects a greater share of descendants, driving selection to rebalance the sex ratio until total parental expenditure on sons equals that on daughters.

Robert Trivers applied the concept of parental investment opportunity costs to explain sexual inequalities and behavioral roles. Parental investment is defined as an opportunity cost measured in lost opportunities to invest in other offspring. Because mothers typically invest more than fathers, members of the low-investing sex compete intensely for the high-investing sex, making males more competitive, brightly colored, and variable in reproductive success.

Molecular clocks and radioactive dating allow scientists to calibrate the timeline of splits in the human family tree. Assuming evolutionary change at the molecular level proceeds at a fixed rate based on Motoo Kimura's neutral theory of neutral mutations, genetic differences can be measured as a clock. Combining this with radioactive dating of volcanic rocks gives absolute dates in millions of years for evolutionary splits.

Fossil discoveries progressing backward include Homo erectus, Homo habilis, Australopithecus afarensis, Ardipithecus, Orrorin, and Sahelanthropus.

Genetic analysis shows that 98 percent of human genome is identical with chimpanzees, with 96 percent resemblance between humans and orang utans, 92 percent resemblance between apes and Old World monkeys, 5 to 8 million years ago for human-chimpanzee split, 14 million years ago for African apes and orang utans split, and 25 million years ago for apes and Old World monkeys split.

Fossil evidence proves that bipedality evolved long before human brains expanded significantly in size. While Darwin guessed that upright posture and brain enlargement happened simultaneously, fossil records demonstrate that Australopithecus was already bipedal with human-like feet three million years ago while retaining a brain size comparable to a chimpanzee.

Human evolution can be understood as neoteny, or evolutionary infantilization, where humans mature sexually while retaining juvenile morphological traits. Juvenile chimpanzees resemble humans far more than adult chimpanzees do. Neoteny allows a lineage to initiate new directions of evolution by halting development at an earlier physical stage, much like the sexually mature axolotl tadpole.

Julian and Aldous Huxley researched neoteny and amphibians like the axolotl, which was featured in Aldous Huxley's novel After Many a Summer, while requiring a hypothetical 200 years lifespan for humans to finally grow up.

3. Information Theory and Genetics

Claude Shannon introduced information theory at Bell Telephone Company in 1948, distinguishing between information, redundancy, and noise. Information is measured as the reduction of ignorance or surprise value, equivalent to the number of yes/no questions needed to reach certainty from a range of alternatives.

A nurse holding up a pink card for a girl halves the expectant father's prior uncertainty from two possibilities, conveying exactly one bit of information.

Genomics functions through digital information technology, where natural selection acts as an information pump preserving ancestral survival instructions.

Genomes possess a total information capacity measurable in gigabits, but much of it consists of repetitive nonsense or pseudogenes. Only a small fraction is actively transcribed into proteins, and the true information content is even smaller once all internal redundancy is compressed out. Humans use only about 2 percent of their total genome capacity, while the crested newt has a genome capacity ten times larger than the human genome due to unused repetitive sequences. There is a 3 orders of magnitude increase in human genome information capacity compared to bacterial ancestors, and the crested newt reaches an estimated 40 gigabits.

Genes duplicate and diverge over millions of years, creating internal family trees of related genes within the same genome. Human adult haemoglobin is a composite of alpha and beta globin chains whose genes reside on different chromosomes, having split from an ancient gene about 500 million years ago. Each alpha globin chain contains 141 amino acids, and each beta globin chain contains 146 amino acids.

Natural selection narrows down random genetic variations, discarding unsuccessful genes and retaining successful ones. Camel DNA has been sculpted by survival in ancient deserts, preserving a coded description of ancestral environments known as the Genetic Book of the Dead.

The Future of Sequencing

Genes operate as blueprints during protein translation, but function more like recipes when interacting to form complex bodies and psychological traits. A blueprint features a strict one-to-one, reversible mapping between components and the final product, which applies when DNA translates into precise protein shapes. The discovery of genetic markers near the Xq28 region linked to male homosexuality indicates a statistical predisposition rather than absolute genetic determinism.

DNA sequencing power follows an exponential growth trend dubbed Son of Moore's Law, with sequencing costs halving every twenty-seven months. Sequencing costs dropped from about 1000 pounds per letter in 1965 to 10 pounds per letter in 1975, 1 pound per letter in 1995, and about 0.1 pounds per letter around 2000 during the Human Genome Project.

Advances in genomics and embryology by 2050 will enable complete species tree mapping and the potential physical reconstruction of extinct ancestors. Comparing human and chimpanzee genomes could allow researchers to computationally reconstruct the genome of their common ancestor and bring an australopithecine like Lucy back through surrogate implantation.

4. Memes and Viruses of the Mind

Culture evolves through self-replicating elements passed on by imitation. You can trace this cultural analogue to the gene across words, ideas, faiths, mannerisms, and fashions. On 29 August 1998, the Oxford English Dictionary listed 5042 mentions of the adjectival form memetic on the World Wide Web, while the alt.memetics newsgroup received about 12000 postings over the past year.

Cultural ideas replicate like genes through imitation, and religious dogmas operate as pernicious mind viruses that exploit vulnerable children.

Richard Dawkins acquired the intonations and speech manners of his Oxford tutor Peter Brunet. He later observed a pupil whose gesture of screwing her eyes shut and freezing was recognized by a philosopher as a direct imitation of Wittgenstein passed through her parents.

The Science of Memetics

Cultural transmission works with high fidelity when you copy instructions rather than copying the end product directly. In Lamarckian inheritance, you pass on the phenotype directly, leading to rapid degradation like the game of Chinese Whispers. In Weismannian inheritance, what passes down is a self-normalizing, error-correcting set of instructions that prevents progressive deterioration.

You can experience this transmission in an origami experiment where children teach each other how to fold a paper Chinese junk using instructions. Quantitative errors or clumsy folds made by one child are corrected by the next child rather than perpetuated. Richard Dawkins learned this Chinese junk origami from his father and reintroduced it to a new school cohort 25 years later.

To test this replication yourself, follow these steps:

• Take a square sheet of paper and fold all four corners exactly into the middle.
• Take the reduced square so formed, and fold one side into the middle.
• Fold the opposite side into the middle, symmetrically.
• In the same way, take the rectangle so formed, and fold its two ends into the middle.
• Take the small square so formed, and fold it backwards, exactly along the straight line where your last two folds met.

Infections of Faith

Computers and cellular machinery share two qualities that make them friendly to parasitic replicators: a readiness to replicate information accurately and a readiness to obey instructions encoded in that information. Successful viruses avoid detection and prevent immediate destruction so they can spread widely. The Internet Worm paralyzed much of the computing power of the United States on 2 November 1988 by clogging around 6000 computer memories within 24 hours.

Human children are evolutionarily preprogrammed to absorb a large dictionary, syntactic rules, and encyclopedic information before reaching half their adult size. Because you must acquire vast amounts of cultural data rapidly, your mind is exceptionally gullible and wide open to subversion by pernicious information. A trusting six-year-old child believes in Father Christmas, Thomas the Tank Engine, and witches changing princes into frogs, and is sent for weekly instruction to a Roman Catholic nun without her father's consent.

Certain religious and memetic doctrines are favored precisely because they are ridiculous or burdensome. Drawing an analogy to Amotz Zahavi's handicap theory in sexual selection where peacocks evolve burdensome tails to prove their strength, religious doctrines that demand belief in impossible things act as costly handicaps that test and authenticate the believer's commitment. A rabbi scrutinizing menthol ingredients in China for kosher purity explains that Kashrut laws are intentionally arbitrary divine ordinances without reason given precisely because following them is 100 per cent difficult.

Mind viruses sustain themselves by making a virtue out of a lack of evidence and treating mystery as an intrinsic good. The Reverend Jim Jones led more than 900 followers of the Peoples' Temple sect to drink cyanide in Jonestown after calling his flock together to demonstrate dignity in dying.

Science is not a virus because the selective forces scrutinize ideas based on exacting methodological standards rather than arbitrary self-serving propagation. Anthony Kenny eventually renounced his Catholic priestly orders after three decades because he could no longer tolerate the obvious contradictions within Catholic belief, transitioning to a respected scholar.

5. Science, Religion, and Skepticism

Organized religion demands unearned social deference and promotes dangerous divisions, while science offers the only reliable method for discovering objective reality.

Some thinkers use religious vocabulary metaphorically. This creates a false impression of convergence between science and religion. Ursula Goodenough's book The Sacred Depths of Nature is marketed as religious and praised by theologians. Yet she does not believe in a supreme being or life after death, making her views identical to atheist viewpoints. Redefining secular awe as religion creates semantic confusion.

Quantum mechanics is frequently hijacked by mystics to peddle pseudoscientific nonsense. Psychiatry professor Patricia Newton lectured on Afrocentric healing, claiming traditional healers tap into negative entropy and superquantum velocity.

Separate Magisteria

Religious apologists claim religion stays off science's turf when speaking to intellectuals. Yet they rely on miracle stories like the Virgin Birth to recruit uneducated audiences. These miracles constitute explicit scientific claims. Pope Pius XII declared the bodily Assumption of the Blessed Virgin Mary to be an infallible dogma of the Catholic Faith in 1950. It took the Vatican 350 years to reconcile with Galileo after his death.

Agnostic conciliation treats unfounded religious claims as if they hold equal weight simply because a negative cannot be conclusively disproven. Bertrand Russell argued that we cannot disprove the existence of a china teapot orbiting the Sun, yet we do not treat the teapot theory as valid. If a belief cannot be supported by empirical evidence, it deserves no more validation than an orbiting celestial teapot.

Deference to Faith

Society grants unearned deference and automatic respect to religious opinions in media, education, and politics. During media discussions following the cloning of Dolly the sheep, religious leaders were invited despite displaying profound ignorance of biology and physics. Political views must be defended through logic and evidence, while religious views are treated as off-limits.

Religion acts as the most inflammatory and dangerous enemy-labelling device in human history, dividing communities and perpetuating generational vendettas. The September 11 terrorist attacks and the subsequent National Day of Prayer united mutually incompatible faiths in homage to the very force that caused the problem.

Douglas Adams viewed the natural complexity of the universe through evolution as a source of awe far superior to religious ignorance. Adams wrote The Hitchhiker's Guide to the Galaxy and created concepts like the Infinite Improbability Drive, deeply rooted in scientific thinking. At Adams's memorial service at St Martin in the Fields, heartfelt tributes, music, and readings celebrated his life far better than standard religious rites could have.

Adams famously illustrated cognitive bias using the puddle analogy, describing a puddle waking up to find itself in a hole. The puddle concludes that the hole fits it so neatly it must have been designed specifically to hold it, right up until the moment it evaporates. This teleological illusion makes people falsely assume a creator designed the cosmos for human existence.

6. Methodology, Alternative Medicine, and Truth

Rigorous double-blind testing and empirical evidence are required to dismantle pseudoscientific alternative medicine and protect objective truth.

The human mind naturally seeks patterns and creates stories where none exist, making statistical analysis and controlled experiments necessary to discover objective truths. Personal anecdotes are unreliable evidence because human psychology easily mistakes randomness for design. Ray Hyman tested kinesiology practitioners in experiments where alternative muscle-strength diagnostic claims collapsed entirely under double-blind conditions.

Testing Homeopathy

Alternative medical practices like homeopathy fail basic scientific standards and should be tested using rigorous double-blind, randomized methodologies. Prince Charles called for 10,000,000 pounds of government money to research alternative medicine, while alternative practitioners consistently avoid funding tests that would expose their lack of efficacy. James Randi calculated that after typical homeopathic succussive dilutions, a single molecule of the active ingredient would remain in a vat the size of the solar system.

To evaluate such claims fairly, you can design a clinical test using clear experimental steps:

• Obtain consent from 1000 patients and separate them into 500 experimental and 500 control subjects
• Have every patient examined by a certified homeopath to prescribe individually tailored therapy
• Use a computer to randomize half the prescriptions to omit the supposed active ingredient as a blind control
• Ensure patients, therapists, pharmacists, and judges remain completely unaware of group assignments using coded bottles
• Record medical judgments before and after treatment, break the computer codes, and analyze results statistically

The Pattern-Seeking Mind

John Diamond demonstrated vital intellectual courage by refusing false comforts and alternative miracle cures during his terminal battle with cancer. John Diamond wrote movingly about his affliction and rejected alternative cancer treatments despite being inundated with well-intentioned advice and false miracle offers. Diamond exposed how pushers of dishonest alternative remedies exploit vulnerable patients for financial gain.
