Sex--The Unknown Quantity: The Spiritual Function of Sex

Alexander J. (Alexander James) McIvor-Tyndall (d. 1940)

Philosophy & Ethics6 min read·1,280 words

This exploration of human intimacy argues that the secret to a meaningful life lies not in physical indulgence, but in the spiritual alchemy of the sexes. It posits that true union requires transcending the animal nature to achieve a higher state of consciousness.

In Short

This book is a philosophical treatise from 1916 that attempts to reframe sexuality as a sacred, cosmic force rather than a mere biological function. It critiques the restrictive social norms and hypocrisies of early 20th-century marriage, advocating instead for "spiritual counterpartal affinity." By blending historical symbolism, mysticism, and social commentary, the text seeks to guide the reader toward a state of freedom and internal integrity. It has remained a curiosity of the New Thought movement, documenting the early intellectual pushback against Victorian-era repression and rigid gender roles.

The Story

Advertisement

The narrative arc of the book begins by establishing the "fundamental basis of the universe" as sex itself. The author posits that early civilizations understood this sacred connection through nature-based worship, but warns that humanity has since fallen into a state of "sex-degradation." The argument moves through history, exploring how the shift from the worship of the female generative principle to the male phallic principle led to a loss of balance, resulting in the enslavement of women and the rise of profligate, animalistic behaviors that still plague modern society.

As the book progresses, the focus shifts to the institution of marriage. The author argues that modern legal marriage is often a hollow shell, frequently based on ownership, economic expediency, or social conformity rather than genuine love. The text maintains that true marriage is a "scientific possibility" occurring only when two spiritual counterparts align. The author harshly critiques the "Eugenic" movements of the time for ignoring the soul in favor of physical breeding, comparing such efforts to the cold, unbalanced practices of ancient Rome and Greece, which ultimately led those civilizations to ruin.

The middle chapters confront the painful reality of sexual exploitation, specifically addressing the "white slavery" of the period. Here, the author challenges the reader to look past the superficial definition of "chastity," which he considers a commercialized mask, and instead demand an honest, equal moral standard for both sexes. He argues that the stigma surrounding unmarried mothers is a symptom of a society that prioritizes property and reputation over human life and spiritual truth.

The final phase of the book explores the path toward "Regeneration." The author introduces the reader to the idea of "transmuting" sexual energy into higher creative and spiritual channels. By looking at mythological symbols—such as the Ark of the Covenant or the union of the sun and moon in alchemy—he illustrates that these stories were never meant to be taken literally, but were instead allegories for the inner, spiritual union of the masculine and feminine qualities within every individual. The journey concludes with a call for the reader to abandon the desire to "possess" a partner. Instead, the author advocates for a future where humanity is free from the coercion of vows and false moralities, ultimately finding a "Social Paradise" through the selfless, spiritual understanding of the creative power of love.

How It Unfolds

The universal principle The book opens by defining sex as the primary, eternal source of all life. It asserts that human progress depends on moving beyond current, debased interpretations of this power.

Historical decline The author traces the evolution of sex-worship, arguing that humanity’s descent from reverent nature-worship into power-hungry phallic cults caused our current cultural fragmentation.

Marriage as a construct The text pivots to examine the institution of marriage, contrasting the "perfect" union of spiritual counterparts with the "coercive" legal contracts that characterize modern society.

The anatomy of deception The argument deepens by attacking the societal hypocrisy regarding chastity and virtue. The author condemns the way traditional morality creates a culture of secrecy and exploitation.

The path of transmutation The author outlines a method for the individual to evolve, suggesting that sexual energy must be transmuted into "interior functions" to achieve personal and collective growth.

The ideal of freedom The conclusion dismisses the need for rigid marriage vows in favor of mutual confidence. The book ends by urging the reader to prioritize soul-level unity over the animal instinct for possession.

The People

The book is less a character-driven narrative and more a discourse addressed to the "intelligent public" and the "Child of Tomorrow." Central to the text is the Man-God, the archetypal figure of evolved humanity that the author believes we are all awaiting. This figure represents the potential for every person to transcend their "animal nature." The Unmarried Mother also serves as a pivotal, sympathetic figure in the author’s critique; she is presented as a victim of a society that equates moral worth with legal status. Opposing these figures are the "Self-constituted Keepers of Morality," including civic leaders and clergy members who, in the author's view, are blinded by fear and "mental perverts" who see only decay where there is sacred mystery. Finally, the "Alchemist" appears as a symbolic seeker—a master who understands that true power comes not from turning lead to gold, but from finding one’s true spiritual counterpart to achieve illumination.

In Its Own Voice

"The fundamental basis of the universe is Sex."

This statement serves as the author's opening thesis, establishing his premise that the sex-function is the core of all reality.

"Possession! that is the word that spells unhappiness, in married life; each wants to possess the other; neither one tries for the spirit of union."

The author uses this observation to critique the core flaw he perceives in traditional, possessive marriage models.

"The love that is of the soul fills the breast first of all, and is only felt in the region popularly, but erroneously, supposed to circumscribe the sex-function, as a secondary and by no means compulsory consideration."

This passage encapsulates the author’s spiritual argument, distancing true love from the physical organs of procreation.

What It's Really About

At its heart, this book is an argument for the "spiritualization" of human desire. It seeks to resolve the tension between our physical reality and our desire for a higher, more meaningful existence. The central question asks whether humanity can move past its "animal" instincts—such as greed, jealousy, and the drive to possess—to establish a society based on unity and mutual respect. The book posits that our current social problems, including divorce, prostitution, and war, are all symptoms of our failure to understand that the creative energy of sex is the same energy that, when properly channeled, leads to spiritual enlightenment. It is a work about the evolution of the human consciousness from the external to the internal.

Why Read It Today

Readers interested in the history of alternative spirituality and the early 20th-century movements that challenged Victorian morality will find this a fascinating document. It is written with a sense of urgent, prophetic fervor that is characteristic of the New Thought era. You will feel the author’s frustration with the "slow-moving mind" of his peers, which adds a visceral, human tone to the philosophical density of the text.

However, the modern reader should be prepared for the book's significant challenges. The author’s prose is grand and sometimes repetitive, often favoring sweeping, unproven declarations about "cosmic laws" over empirical evidence. The references to historical figures and ancient mysticism are used loosely, which may frustrate those looking for scholarly rigor. Furthermore, the reader will encounter period-specific attitudes that, while intended by the author as progressive, can strike a modern ear as dated or patronizing. The book is an artifact of a specific intellectual moment; it is best approached as a window into the bold, often contradictory, and deeply idealistic quest for a new definition of the self at the turn of the century. It stays with you because it forces a confrontation with the very things we still struggle to discuss openly: the intersection of our deepest biological drives and our highest spiritual aspirations.
