Science and the Infinite

In Short

Written to comfort the suffering and dying, this treatise bridges early twentieth-century scientific discoveries with mystical theology. Sydney T. Klein systematically examines how finite human senses warp reality, arguing that space and time are merely conceptual limits rather than objective truths. By integrating concepts from physical optics, geometry, frequency spectrums, and natural history with Christian mysticism, Klein demonstrates that the physical universe is a temporary shadow of a eternal spiritual reality. The book endures as a fascinating artifact of early modern attempts to harmonize rigorous physical science with spiritual devotion.

The Story

Klein begins his argument by framing human perception as an imperfect filter. Earthly senses react only to motion and change, leaving humans trapped within artificial boundaries of space and time. To illustrate how easily perception misleads, Klein contrasts light and sound, noting how the brain constructs an illusion of solid reality from rapid, discrete atomic movements, much like a swarm of bees appearing as a single dense object from afar.

Moving into philosophical synthesis, Klein posits that every individual possesses two distinct personalities: a physical ego bound to finite senses and a transcendental spiritual self unconditioned by space or time. True insight requires stepping beyond the physical ego to perceive the spiritual reality behind material phenomena. To ground this belief historically, Klein turns to classical geometry and medieval architecture. He highlights Plato’s insistence on geometry as the key to eternal truth and traces how medieval masons embedded sacred geometry—specifically the Vesica Piscis and the equilateral triangle—into Gothic cathedrals as physical symbols of the Divine Logos.

Klein then expands his lens to physical science, tracing how all material structures derive from uniform protoplasmic cells and fundamental atomic bricks. He argues that the entire natural world operates through a principle of influence and sympathy. Drawing on Charles Darwin's theories, Klein reinterprets biological adaptation as a form of natural "prayer," where organisms must bring themselves into harmony with their environment to survive. He extends this concept to physics through experiments with acoustic resonance and vibrating iron bars, demonstrating that inert matter responds powerfully when touched by frequencies tuned to its innate characteristics.

Finally, Klein addresses the mysteries of scale and temporal perception. He charts the vast electromagnetic spectrum—from radio waves to visible light and chemical rays—showing that human vision apprehends only a fraction of existing physical reality. He then explores time perception through thought experiments, demonstrating how changing our rate of sensory processing alters our experience of duration, making a brief moment feel like millennia or an entire lifetime pass in minutes. Through examples like Mozart hearing a full symphony instantaneously in his mind, Klein concludes that time and space are merely tools for processing experience sequentially. The ultimate goal of human existence is introspection—knowing oneself to realize that the human soul is an eternal emanation of the Divine Absolute.

How It Unfolds

The limits of perception Klein opens by showing how human reliance on sensory excitation creates false concepts of continuous time, space, and physical solidity.

The dual nature of man He divides human identity into a finite physical ego and an omnipresent transcendental self that exists outside spatial and temporal limits.

Sacred geometry and form Tracing Hellenic philosophy and Gothic architecture, he explains how geometric figures like the Vesica Piscis serve as physical symbols of eternal truths.

The unified physical world He examines biology and atomic theory, arguing that all living organisms and material elements are built from identical fundamental components.

Sympathy and natural prayer Integrating Darwinian evolution and acoustic physics, he demonstrates how survival and resonance both depend on an entity aligning with its environment.

The vast invisible spectrum By mapping electromagnetic frequencies, he reveals that human eyes and ears perceive only a tiny sliver of the actual physical universe.

The relativity of time Through mental experiments and artistic creation, he illustrates how time perception is an artificial framework constructed by the physical brain.

The return to the absolute He closes by calling for deep introspection, asserting that the soul realizes its true immortality by recognizing its oneness with God.

The People

The Physical Ego The temporal human identity that relies entirely on sensory inputs, sequential thought, and physical motion to understand its surroundings. It wants to organize existence into measurable units of space and time, but it remains constantly deceived by illusions of solidity, distance, and physical death.

The Transcendental Ego The true spiritual self present within every human being, unbound by temporal or spatial constraints. It seeks union with the divine reality and can only be accessed when the physical ego is quieted through self-forgetting and mystical contemplation.

Plato and the Ancient Geometers Historical thinkers who recognized geometry as the supreme science capable of revealing absolute, unchangeable truth. They viewed God as a divine architect constantly geometrizing the universe, using mathematical proportions to bridge the physical world and eternal concepts.

Charles Darwin The evolutionary biologist whose principles of natural selection and environmental harmony Klein adapts. Within the argument, Darwin represents the bridge between physical observation and spiritual law, demonstrating that all living things must adapt to their surroundings to survive.

In Its Own Voice

"Many of us allow ourselves to be overwhelmed by the small worries and vexations of everyday life, clothing them with a reality quite disproportionate to their importance..."

Klein frames his philosophical inquiry in the preface as a practical cure for daily anxiety and the fear of mortality.

"A fair analogy would be to liken it to a swarm of bees, for we know that it is composed of an immense number of independent atoms or molecules which are darting about..."

He illustrates the deceptive nature of human touch, explaining that objects appearing solid are actually composed of rapidly moving particles.

"The whole of what we call Creation... is but the sensuous expression of the Reality..."

In describing the mystical state, Klein asserts that the physical universe is merely an outward, sensory manifestation of a deeper spiritual truth.

What It's Really About

At its core, the book argues that scientific discovery and spiritual mysticism are not opposing forces, but two ways of observing the same fundamental reality. Klein contends that human suffering, fear of death, and existential confusion stem directly from mistaking physical sensory inputs for absolute reality. By using early twentieth-century advances in physics, wave theory, and evolutionary biology, he attempts to demonstrate scientifically that material existence is merely a limited projection. The work ultimately aims to reframe religious faith as an exact, introspective science, urging readers to look past temporal illusions to find peace in an omnipresent, non-physical God.

Why Read It Today

This work offers a captivating look at Edwardian intellectual history, capturing a moment when cutting-edge physical sciences were eagerly embraced to validate spiritual experiences. Readers interested in the historical intersection of science, esoteric geometry, and Christian mysticism will find Klein's synthesis unique and thought-provoking. His prose maintains a gentle, compassionate tone born out of a desire to comfort the terminally ill, making complex scientific analogies feel personal and accessible.

Modern readers should be prepared for period-specific prose structures and dense thematic leaps, as Klein moves swiftly from optical physics to Plato, Gothic masonry, and biological evolution within a few pages. Some of his scientific references reflect the state of research in 1912—such as early atomic models and ether theories—and his evolutionary analogies take creative liberties with Darwinian theory. Nevertheless, the book’s core contemplation of time, sensory limitation, and the search for meaning beyond material appearances remains deeply engaging for anyone fascinated by the boundaries of human perception.
