Outgrowing God

Outgrowing God Plot Summary

Introduction

Religion has been a dominant force in human civilization for millennia, shaping cultures, morals, and worldviews. Yet the advancement of scientific knowledge and critical thinking has increasingly challenged traditional religious beliefs. This intellectual journey—from faith to reason—represents one of humanity's most profound transformations. The question of whether belief in God is necessary or rational forms the central exploration, examining both the psychological and intellectual foundations of religious faith. The arguments presented tackle fundamental questions about the origins of religious belief, the historical reliability of sacred texts, the formation of myths, the relationship between morality and divine command, and how scientific understanding—particularly evolution—provides compelling alternative explanations for phenomena once attributed to divine design. Through careful logical analysis and examination of evidence, this exploration not only challenges religious dogma but also offers a framework for understanding the natural world and human ethics without reliance on supernatural forces. This journey ultimately leads to a more coherent understanding of reality based on evidence rather than faith.

Chapter 1: Religious Diversity and the Problem of Many Gods

Throughout human history, thousands of gods have been worshipped across different cultures and time periods. Polytheistic religions like those of the ancient Greeks, Romans, and Vikings featured pantheons with numerous deities—each responsible for different aspects of life and nature. The Viking gods included Wotan (Odin), Thor, and Baldr, while Greek and Roman mythology featured Zeus (Jupiter), Poseidon (Neptune), and Aphrodite (Venus). Even today, Hinduism embraces thousands of deities. The remarkable diversity of religious beliefs presents a logical challenge to the truth claims of any particular religion. If you were born in ancient Greece, you would likely have believed in Zeus and Apollo rather than in Yahweh. If born in modern Pakistan or Egypt, you would probably believe Jesus was merely a prophet rather than the Son of God. The geographic and cultural distribution of religious beliefs strongly suggests that faith is primarily determined by accident of birth and cultural inheritance rather than objective truth. Children often inherit their parents' religious affiliations before they can develop critical thinking skills. This observation leads to the uncomfortable realization that if diverse religious beliefs contradict each other, they cannot all be correct. The sheer variety of mutually exclusive religious claims throughout history suggests that humans have a tendency to create gods rather than gods creating humans. Even within monotheistic traditions, inconsistencies emerge. Christianity, despite claiming monotheism, includes elements that resemble polytheism: the Trinity concept, Satan as a powerful supernatural antagonist, and (in Catholicism) the veneration of Mary and numerous saints. Muslims and Jews might view these practices as effectively polytheistic, despite Christians' insistence otherwise. These theological contradictions further undermine the coherence of exclusive religious truth claims. Modern secular positions range from explicit atheism (the rejection of belief in any gods) to agnosticism (the view that we cannot know whether gods exist) to various forms of deism or pantheism (belief in abstract or non-personal conceptions of divinity). What unites these perspectives is the recognition that the specific, anthropomorphic gods of traditional religions likely represent human cultural creations rather than cosmic realities. The multiplicity of contradictory religious beliefs throughout history provides strong evidence that gods are human inventions, not divine revelations.

Chapter 2: Historical Reliability of Religious Texts

The historical reliability of religious texts—particularly the Bible—faces significant challenges when subjected to critical examination. The New Testament gospels, often presumed to be eyewitness accounts, were actually written decades after the events they purport to describe. Mark, the earliest gospel, appeared approximately 35-40 years after Jesus's death, while Matthew, Luke, and John came even later. This substantial time gap allowed for considerable distortion through oral transmission. Authorship of biblical texts presents another problem. Despite traditional attributions, scholars widely agree that the gospels were not written by eyewitnesses or direct associates of Jesus. Matthew was not written by the tax-collector disciple, nor John by "the beloved disciple." Instead, these attributions were later traditions with little historical foundation. The gap between events and documentation, combined with uncertain authorship, undermines claims of historical accuracy. External historical corroboration for biblical narratives is remarkably sparse. Outside the gospels, contemporary historical references to Jesus are minimal. Josephus, a Jewish historian writing in the late first century, briefly mentions Jesus, but scholars suspect the most theological portions of this reference were later Christian interpolations. The Roman historian Tacitus makes a passing reference to "Christus" being executed under Pontius Pilate, but provides no details that would confirm gospel narratives. Internal contradictions between gospel accounts further challenge their historical reliability. The gospels disagree on fundamental details: Matthew and Luke present contradictory genealogies for Jesus; birth narratives differ substantially; accounts of Jesus's resurrection contain irreconcilable elements. These discrepancies suggest theological agendas rather than historical reporting. Matthew's gospel particularly reveals an obsession with demonstrating fulfilled prophecies, even when this requires strained interpretations of Old Testament texts. The gospel authors' evident theological motivations compromise their historical objectivity. For instance, Matthew's account of Jesus's virgin birth stems from a mistranslation of Isaiah, where the Hebrew word "almah" (young woman) became "parthenos" (virgin) in the Greek Septuagint. Such theological imperatives shaped the narrative more than historical accuracy. Similarly, both Matthew and Luke contrive different explanations for Jesus's birth in Bethlehem to fulfill prophecy, despite evidence suggesting he was from Nazareth. Critical historical methodology requires extraordinary evidence for extraordinary claims. While a wandering preacher named Jesus may well have existed in first-century Palestine, claims about virgin birth, miracles, and resurrection lack the robust historical evidence that would justify their acceptance. When we apply the same historical standards to biblical texts that we would to any ancient document, their reliability as factual accounts becomes highly questionable.

Chapter 3: Myth Formation and Cultural Transmission

Myths emerge and evolve through recognizable patterns of cultural transmission and transformation. Religious stories, despite their sacred status for believers, follow the same patterns of development as other cultural narratives. The Bible contains numerous examples of myths whose origins can be traced to earlier cultural sources. The Genesis flood narrative, for instance, closely parallels the older Mesopotamian Epic of Gilgamesh and its story of Utnapishtim, suggesting cultural borrowing rather than independent historical accounts of the same event. The "Chinese Whispers" effect (also known as the "Telephone Game") explains how stories naturally change as they pass through multiple retellings. Each person in the transmission chain introduces subtle modifications—emphasizing certain elements, forgetting others, reconciling apparent contradictions, or embellishing for dramatic effect. Over generations, these cumulative alterations can substantially transform a narrative while preserving its core motifs. This process explains why similar mythic themes appear across cultures with distinctive variations. Modern myth formation provides observable examples of this process. The cargo cults of Melanesia emerged when isolated islanders encountered technologically advanced military forces during World War II. Having no framework to understand aircraft delivering supplies, they developed rituals and beliefs aimed at attracting these "gifts from the gods," complete with wooden "control towers" and imitation airstrips. Similarly, the contemporary cult venerating Prince Philip on Vanuatu demonstrates how deification can occur even in modern times. These examples reveal the sociopsychological mechanisms behind religious myth formation. Religious movements can emerge with remarkable speed. Mormonism, founded by Joseph Smith in the 1820s, has grown into a worldwide religion with millions of adherents despite its recent origins and considerable evidence contradicting its historical claims. Smith's "translation" of ancient Egyptian documents (later proven to be standard funeral texts unrelated to his claims) demonstrates how religious authority can override empirical evidence. The rapid growth of Mormonism illustrates how religious movements can thrive despite factual contradictions. The widespread similarities in myths across cultures reveal common patterns in human psychology and social organization rather than divine revelation. Creation myths, flood stories, virgin birth narratives, and dying-and-rising god motifs appear across numerous unconnected cultures. These parallels suggest that myths emerge from universal human experiences, cognitive biases, and social needs rather than historical events or supernatural interventions. The cross-cultural ubiquity of certain mythic patterns undermines claims that any particular religious tradition uniquely represents divine truth. Understanding myth formation reveals that religious narratives follow predictable patterns of cultural evolution rather than divine preservation of historical truth. Appreciating myths as powerful cultural expressions does not require accepting their literal truth claims. Indeed, the documented processes of myth formation provide a more parsimonious explanation for religious stories than supernatural intervention.

Chapter 4: Morality Without Divine Command

The relationship between religion and morality represents one of the most persistent misconceptions in ethical thinking. Many religious believers assume that without divine commands, morality would have no foundation and ethical behavior no motivation. This assumption, however, fails to withstand critical examination. Moral intuitions and ethical reasoning operate effectively without religious foundations, as demonstrated by the moral lives of non-religious individuals and societies. Historical examination reveals that morality has evolved significantly over time, often in directions contrary to traditional religious teachings. Attitudes toward slavery, women's rights, and treatment of minorities have undergone radical transformation in recent centuries. These moral advances frequently occurred despite religious resistance rather than because of it. Religious texts themselves contain moral prescriptions—such as endorsements of slavery, ethnic cleansing, and severe punishments for minor offenses—that modern believers typically reject or reinterpret. This selective approach to religious ethics suggests that believers already employ independent moral judgment that transcends scriptural authority. Empirical evidence contradicts the claim that religiosity correlates with ethical behavior. Secular societies in Northern Europe consistently rank among the most peaceful, equitable, and compassionate by objective measures. Within the United States, prison populations show religious believers dramatically overrepresented relative to atheists. While individual religious communities certainly inspire moral excellence among their members, the broader pattern suggests morality functions independently of religious belief. Philanthropic giving, volunteer work, and humanitarian efforts flourish among both religious and non-religious populations. Divine command theory—the idea that actions are right because God commands them—faces the insurmountable philosophical challenge articulated in Plato's Euthyphro dilemma: Is something good because God commands it, or does God command it because it is good? If the former, morality becomes arbitrary; if the latter, moral standards exist independently of divine will. Either way, divine commands cannot serve as the ultimate foundation for ethics. This philosophical problem reveals that even theistic morality requires standards of goodness that transcend mere divine decree. Alternative foundations for ethics exist in human experience, reason, and natural social instincts. Empathy, reciprocity, and cooperation emerge naturally from human social nature without requiring supernatural reinforcement. Secular ethical frameworks—from utilitarianism to Kantian ethics to virtue ethics—provide robust systems for moral reasoning without appealing to divine authority. These approaches ground morality in universal human experiences and rational principles accessible to believers and non-believers alike. The evolution of moral thinking demonstrates that ethical progress comes through rational reflection, expanded empathy, and social dialogue rather than religious revelation. The moral arc of history bends toward greater inclusion and compassion not through stricter adherence to ancient texts but through the application of evolving ethical principles to new circumstances. Religion may provide motivational structure and community reinforcement for moral behavior, but the content of ethics derives from human nature and reasoned consideration of wellbeing.

Chapter 5: Evolution as an Alternative to Design

The apparent design in living organisms represented the strongest historical argument for the existence of a creator. From the intricate mechanisms of the eye to the specialized adaptations of predators and prey, living things display levels of complexity and functionality that intuitively suggest intentional design. This appearance of design posed a formidable intellectual challenge to naturalistic explanation until Darwin's theory of evolution by natural selection revolutionized our understanding. Evolution through natural selection operates through a surprisingly simple mechanism with profound explanatory power. Random genetic variations continually arise in populations. Most variations are neutral or harmful, but occasionally beneficial variations emerge that enhance survival or reproduction in a particular environment. Individuals possessing these advantageous traits leave more offspring, who inherit these beneficial variations. Over generations, adaptive traits accumulate, gradually producing organisms exquisitely adapted to their environments. This process requires no foresight, planning, or designer—only the non-random selection of random variations. The power of cumulative selection explains how complexity emerges incrementally over evolutionary time. Each small improvement builds upon previous adaptations, creating structures of astounding sophistication through countless small steps. The vertebrate eye, often cited as too complex to have evolved naturally, demonstrates this principle. Comparative anatomy reveals a spectrum of light-sensitive structures across animal species, from simple photosensitive cells to fully-formed camera eyes. Each intermediate form provides survival advantages, making the evolutionary pathway both plausible and well-documented. Evolutionary explanations surpass design hypotheses in accounting for the flaws and quirks observed in living organisms. The recurrent laryngeal nerve in mammals makes an absurdly circuitous route from the brain to the larynx, looping unnecessarily around the aorta—a peculiarity perfectly explained by evolutionary history but inexplicable as intelligent design. Similarly, the backward wiring of the vertebrate retina, vestigial structures like the human appendix, and numerous other "design flaws" make sense as products of evolutionary history constrained by previous adaptations. The evidence for evolution spans multiple scientific disciplines, creating an overwhelming convergence of support. Fossil records document transitional forms across major evolutionary transitions. Comparative anatomy reveals structural homologies indicating common descent. Biogeography—the distribution of species across continents—aligns perfectly with evolutionary predictions but contradicts creation accounts. Most definitively, molecular genetics provides a precise record of evolutionary relationships through DNA similarities that exactly match the patterns predicted by common descent. Natural selection provides a complete explanation for apparent design without requiring a designer. This represents perhaps the single most significant intellectual revolution in human understanding of the natural world. By demonstrating how blind physical processes can generate complex, functional systems, evolution removes the strongest traditional argument for divine creation. The power of natural selection to explain biological complexity undermines the need to invoke supernatural design in understanding the living world.

Chapter 6: The Self-Assembly of Complexity in Nature

Complex order emerges spontaneously throughout nature without requiring external design or direction. Crystallization exemplifies this principle: the geometric precision of snowflakes and mineral crystals results from the self-organizing properties of molecules following simple physical laws. Each snowflake's intricate six-fold symmetry emerges not from a designer's blueprint but from the atomic structure of water molecules as they freeze. This natural process demonstrates how complexity can self-assemble from simple components following basic rules. Biological self-assembly occurs at multiple levels of organization. Proteins—the molecular machinery of living cells—spontaneously fold into precise three-dimensional structures determined by their amino acid sequences. This folding follows physical principles similar to crystallization, where molecular forces guide components into energetically favorable arrangements. The lambda bacteriophage virus exemplifies this process: its complex structure, resembling a lunar landing module, self-assembles from protein components without external direction, demonstrating that highly functional biological structures can form through purely physical processes. Embryological development reveals another dimension of natural self-organization. The transformation from a single fertilized cell to a complex organism occurs not through central planning but through local interactions between neighboring cells. Each cell follows simple rules based on its immediate environment and genetic instructions, with no comprehensive "blueprint" of the final organism. Computer simulations demonstrate that complex, coordinated structures emerge when individual elements follow local rules—just as flocking birds create mesmerizing aerial patterns without a choreographer. Bottom-up processes fundamentally differ from top-down design. Human-engineered systems typically involve blueprints, specifications, and centralized control—a designer conceives the whole before constructing the parts. By contrast, natural systems emerge through local interactions without centralized control or preconceived plans. This distinction between bottom-up emergence and top-down design proves crucial for understanding biological complexity: living systems develop through evolutionary processes that have no foresight or planning, yet produce structures of remarkable sophistication. The chemical foundation of life illustrates self-organization at the molecular level. Enzymes—proteins that catalyze specific chemical reactions—create order in cellular chemistry through molecular recognition. Like precisely shaped jigsaw pieces, enzymes selectively bind to specific molecules, facilitating chemical transformations without requiring conscious direction. This molecular selectivity, multiplied across thousands of different enzymes, coordinates the intricate dance of cellular metabolism without central control. The ordered complexity of living chemistry emerges from countless local interactions rather than comprehensive design. Self-organizing principles extend beyond biology to cosmic scales. Computer simulations of universe formation, starting with simple physical laws and initial conditions, generate structures remarkably similar to the observed cosmos—complete with galaxies, clusters, and superclusters arranged in complex patterns. The correspondence between these simulations and astronomical observations demonstrates that even the largest-scale structures in nature can emerge through unguided physical processes. From snowflakes to galaxies, complexity self-assembles according to physical principles without requiring external design.

Chapter 7: Scientific Courage and Confronting the Unknown

Scientific progress often requires extraordinary intellectual courage to challenge intuitive assumptions and confront disturbing possibilities. The history of science reveals a pattern: ideas that initially seem absurd or counter-intuitive—that Earth moves around the sun, that continents drift across the planet's surface, that all life shares common ancestry—eventually become established knowledge through evidence and reasoning. This pattern suggests a valuable approach to remaining mysteries: intellectual courage in confronting the unknown rather than retreating to supernatural explanations. Quantum physics exemplifies how scientific understanding can transcend common sense. The Copenhagen Interpretation suggests that quantum events remain undetermined until measured—a notion so counter-intuitive that Schrödinger's famous cat paradox was created to highlight its apparent absurdity. Yet experimental evidence consistently confirms quantum theory's predictions with unprecedented precision. This demonstrates how nature often operates according to principles that violate our intuitions but yield to systematic investigation. Scientific courage involves following evidence even when it leads to deeply unsettling conclusions. The expanding universe and contemporary cosmology present similar challenges to intuition. The concept that space itself expands, that time began with the Big Bang, that our universe might be one among many in a vast multiverse—these ideas strain comprehension. Yet mathematical models based on these counter-intuitive premises accurately predict observable phenomena. The Illustris simulation, modeling cosmic evolution from shortly after the Big Bang, produces structures virtually indistinguishable from actual telescope observations. This predictive success justifies confidence in scientific approaches to ultimate questions. The anthropic principle offers insight into apparent cosmic "fine-tuning" without requiring divine intervention. We necessarily observe a universe compatible with our existence—in a multiverse with varying physical constants, conscious observers would only arise in regions where conditions permit. This perspective transforms the apparent improbability of our life-supporting universe from evidence of design to an expected consequence of observer selection. The anthropic principle exemplifies how scientific reasoning can address profound questions without resorting to supernatural explanations. Throughout history, gods have been invoked to explain phenomena not yet understood through natural processes. The "god of the gaps" approach places divine agency in the diminishing spaces between scientific explanations. Yet the consistent pattern of scientific progress has been to fill these gaps with natural mechanisms, from weather phenomena once attributed to temperamental deities to biological complexity once considered proof of divine craftsmanship. This historical pattern suggests intellectual humility regarding current mysteries: gaps in understanding represent opportunities for discovery rather than evidence for supernatural intervention. The greatest demonstration of scientific courage was Darwin's willingness to confront the apparent design in living organisms with a purely naturalistic explanation. This intellectual breakthrough required extraordinary courage precisely because it challenged humanity's most deeply held intuitions about purpose and design in nature. Darwin's success in explaining biological complexity through natural selection provides a model for addressing remaining mysteries. If science could solve what appeared to be the strongest case for supernatural design—the exquisite adaptation of living organisms—we have reason for confidence that remaining puzzles will yield to similar approaches.

Summary

The journey from religious belief to a naturalistic understanding of reality requires confronting deeply ingrained intuitions and cultural inheritances. Through critical examination of religious diversity, the historical unreliability of sacred texts, the natural processes of myth formation, the independence of morality from divine command, the explanatory power of evolution, and the self-organizing properties of matter, a compelling alternative to supernatural explanations emerges. This intellectual path requires courage but offers a more coherent and evidence-based understanding of our place in the cosmos. The core insight that unifies this exploration is that natural processes—evolution by natural selection, self-organization, emergent complexity—provide more powerful and parsimonious explanations for the phenomena once attributed to divine design. Rather than diminishing our appreciation for life's complexity or the universe's grandeur, this naturalistic understanding enhances our wonder by revealing the remarkable capacity of unguided processes to generate order, complexity, and even consciousness. For those willing to follow evidence where it leads, outgrowing supernatural explanations represents not a loss of meaning but an intellectual coming-of-age—an embrace of reality in all its natural splendor and mystery.
