Natural Man

In Short

This book is a polemical defense of rationalism, arguing that human progress is exclusively the product of physical labor, scientific advancement, and the rejection of theological dogma. It maps the trajectory of humanity from an animal-like existence in "holes in the earth" to a sophisticated society built on technology and reason. By dismissing religious explanations for human origins and morality, the work frames the history of the world as a long, difficult struggle to overcome nature, ultimately positioning secular human effort as the sole source of genuine societal improvement.

The Story

The narrative begins with a firm rejection of the creation stories found in Genesis, favoring instead the theories of Darwin, Haeckel, and Huxley. The author asserts that humanity evolved from primitive, brute-like ancestors—beings that shared an anatomical structure with apes and lacked any inherent morality or sense of justice. In these early, barbaric times, human life was defined by a constant, fearful battle against predatory beasts and rival tribes. Survival required total focus on the immediate struggle for life, and it was only through the slow development of intellect and the control of fire that humans began to secure their environment.

As tribes expanded into nations, the author tracks how humanity began to invent gods to explain the phenomena of the universe. Initially, these deities were fetishes or animal spirits, eventually evolving into anthropomorphic figures created in man's own image. This period of theological development, according to the text, was a product of human credulity and an untrained capacity for observation. The author describes this era as one of spiritual despotism, where priests and monarchs maintained power by fostering ignorance and inciting religious wars. Throughout centuries of institutionalized corruption, the progress of humanity was frequently impeded by the church, which held the mind in "abject bondage."

The arc of the story shifts significantly with the advent of the printing press and the rise of scientific inquiry. The author highlights the courage of early skeptics like Bruno, Vanini, and Galileo, who dared to challenge prevailing theological dogmas despite the risk of persecution or execution. As these seeds of doubt took root, a new era emerged. The focus of human society began to pivot from the "next world" to the tangible needs of the current one. The author argues that the true transformation of the world occurred not through prayer or divine favor, but through the secular labor of mankind—building houses, developing agriculture, and harnessing steam and electricity.

The book concludes by contrasting the failures of theological faith—described as a "ship without a rudder"—with the growing strength of human reason. The author maintains that while humanity has achieved a high level of civilization, the work is far from finished. Significant social inequities, poverty, and systemic injustice remain. The final call to action urges reformers to continue the fight for knowledge and social improvement, insisting that crime and suffering are the results of specific causes that can be remedied through education and better circumstances. The author leaves the reader with a vision of the future where the collective "secular faith" in human progress serves as the primary engine for a more just and enlightened world.

How It Unfolds

The rejection of myth The author immediately challenges the Mosaic account of creation, arguing that modern science has rendered such religious explanations obsolete. He insists that man’s origin is a matter for scientific evidence rather than theological doctrine.

The struggle for survival The text describes early man living in constant terror, competing for life against savage animals. This primitive state is characterized by total ignorance, where cleanliness, truth, and justice were non-existent.

The theological era The author details the rise of religion as a misguided attempt to explain the mysteries of the universe. He describes how priesthoods used this ignorance to exert control, leading to centuries of war and persecution.

The birth of skepticism The narrative moves to the sixteenth century, tracing the dangerous lives of early thinkers who questioned the church. The author celebrates these figures as the necessary catalysts for intellectual freedom and progress.

The age of secular labor The book examines the shift toward industrialization and the triumph of technology over superstition. It posits that steam, electricity, and engineering have done more for human well-being than all religious institutions combined.

The future of reform The final section addresses ongoing social inequalities and the need for continued activism. The author argues that because humanity has successfully used reason to conquer nature, it must now apply that same reason to solve social problems.

The People

The book focuses less on specific individuals than on the archetypes that define human history. The Skeptic—represented by figures like Bruno, Galileo, and Thomas Paine—is the hero of the narrative. These individuals are defined by their courage, their intellectual honesty, and their willingness to face persecution to expose the errors of theology. They stand against the Theologian, who represents the primary obstacle to progress. The theologian is portrayed as a beneficiary of human ignorance, clinging to power by fostering superstition and maintaining spiritual despotism.

The third, central figure is "The Natural Man," the raw material of humanity itself. This figure begins as a barbaric, dirty, and untruthful creature, yet one possessing the latent capacity for improvement. Through the narrative, this natural man evolves into the Modern Secular Worker. This transformation is fueled by "carnal reason," the engine of all societal advancement. Unlike the theologian, who directs his energy toward the afterlife, the secular worker directs his efforts toward improving the material world. By the end of the text, this worker is no longer a subject of religious authority but an autonomous agent responsible for his own liberation and the ongoing improvement of the human condition.

In Its Own Voice

The author highlights the necessity of scientific evidence over ancient tradition when discussing the origins of the human species.

"The researches of men of science lead us to the belief that the authors of the first and second chapters of Genesis were mistaken."

The text argues that the virtues often attributed to natural instinct are actually hard-won cultural achievements.

"Assuredly neither cleanliness nor the love of cleanliness is natural to man, but only the capacity of acquiring a love of cleanliness."

The author emphasizes that secular innovation, rather than spiritual devotion, is the true architect of modern comfort.

"One Stephenson is worth a thousand theologians; one Edison of more value to the world than all the gods that men's imagination have ever pictured."

What It's Really About

The central theme is the triumph of human reason over superstition. The book is an argument for secularism, asserting that morality, justice, and societal advancement are not divinely ordained but are constructed through experience and collective effort. It poses the question: if the universe is governed by laws that are discoverable through science, what role remains for the supernatural? The author concludes that religion has historically served as a tool for control and a barrier to progress, whereas "carnal reason" is the only reliable guide for humanity. The text fundamentally questions the value of faith, suggesting that a focus on tangible, worldly improvement—specifically the alleviation of poverty and the pursuit of knowledge—is the only moral path for a modern society.

Why Read It Today

Readers interested in the history of secularism or the nineteenth-century "Freethought" movement will find this a fascinating, albeit intense, primary document. The author writes with a fierce, uncompromising clarity that makes his position impossible to mistake. However, the modern reader should be prepared for the author’s blunt, Victorian-era language regarding "savage races"—a term and concept used throughout to contrast primitive life with Western industrial progress. This perspective reflects the period’s limitations, and while the author’s arguments for human equality are socially progressive for his time, his anthropological observations are rooted in nineteenth-century biases.

The experience of reading this book is like encountering a polemical pamphlet stretched into a manifesto. It is not a nuanced or balanced historical survey; it is a declaration of war against theological influence in public life. Those who prefer measured academic prose may find the author’s biting, aggressive tone challenging. Yet, the book remains a powerful testament to the fervor of the rationalist movement. What stays with the reader is the author's unwavering conviction that humanity is its own savior. Even if one disagrees with his total dismissal of religion, his celebration of human ingenuity and the persistent, quiet labor that built our modern world is undeniably stirring.
