Monism

“All variations return to one principle; all things in the universe are but different reflections of a single substance.”

I. The Core Definition

Monism posits that the entire universe is ultimately composed of “only one fundamental substance or force.” There is no absolute division between spirit and matter, or between the Creator and the created. We often believe the world is filled with intricately linked yet independent individuals, but this is actually like the relationship between the ocean and its waves: you, me, the flowers, the trees, and the stars are all just different waves rippling on the surface of the same “Cosmic Ocean.” Simply put, the world is not a fractured jigsaw puzzle, but an indivisible, absolute whole.

II. The Core Questions It Seeks to Answer

• The Mind-Body Gap: If the soul (intangible) and the body (tangible) are two completely different things, how is it possible for them to communicate and influence each other? (Attempting to resolve the deadlock of Dualism).
• The Fear of Isolation: In the vast, indifferent universe, are humans truly isolated, helpless outsiders ready to perish at any moment, or are we an indispensable part of this massive living organism?
• The Opposition of God and Nature: If God (the Creator) sits high above, are nature and humanity merely lowly appendages? What exactly is the relationship between God and this material world?

III. Key Tenets and Ideological Breakdown

• The Single Substance:This is the cornerstone of Monism (especially in the Spinozan system). There are no two or more independent substances in the universe. There is no “God” sitting high in the sky independent of the world, nor is there “matter” independent of God. God is Nature itself (Deus sive Natura). The entire universe is the one, infinite, and eternal substance; everything we see is merely a variation within this substance.
• Two Sides of the Same Coin:Monism perfectly solves the dilemma of how “mind and body” interact. It argues that mind and matter are not “interacting” at all, because they are the exact same thing expressed in different dimensions. When you feel sad (a mental attribute), your brain simultaneously secretes stress hormones (a material attribute). Just like the front and profile of the same person, or the sheet music and the sound of the same melody, spirit and matter are an absolutely synchronized, inseparable whole.
• Modes and the Ocean:If the universe is the sole substance, what then are we humans? Monism refers to all independent individuals as “Modes.” You are not an independently existing substance; you are merely a “posture” temporarily expressed by the grand substance of the universe. Just like a brief wave (you) rising on the ocean (the substance). The wave will rise and dissipate, but the essence of the seawater is never diminished. Therefore, all things are absolutely connected at their core.
• Logical Necessity:Since the entire universe is a unified whole, the occurrence of every event is driven by the inevitable chain of causality within this massive system. There is no such thing as an accident, nor are there arbitrary miracles. Understanding this necessity, a person will no longer feel angry or complain about fate, but can accept all things with pure rationality, attaining true “tranquility of mind.”

IV. Key Figures & Quotes

Baruch Spinoza — The 17th-century Dutch philosopher and intellectual giant who developed Monism to its pinnacle; the philosopher most revered by Albert Einstein.

“God or Nature. Whatever is, is in God, and without God nothing can be, or be conceived.”

Parmenides — An ancient Greek philosopher and the patriarch of Western Monism.

“What is, is. All is one, uncreated and indestructible.”

V. Modern Relevance and Reflection

Modern society is highly “fragmented” and “atomized.” We live in concrete boxes, scroll on isolated smartphone screens, and pursue extreme individualism. We feel disconnected from nature (thus we ruthlessly destroy the environment); we view others as mortal enemies in competition (thus we are filled with jealousy and anxiety). This is a severe form of “existential loneliness.”

Monism is the ultimate prescription for curing modern humanity’s “isolation syndrome” and “eco-anxiety.”

When you feel isolated, helpless, and suffocated by stress in this world, Monism invites you to look up at the starry sky or reach down and touch the soil beneath your feet. It tells you: you are not an outsider “thrown” into this universe; you are the eyes and consciousness grown out of the universe itself. The carbon in your body comes from the explosions of ancient stars, and the carbon dioxide you exhale will become the leaves in tomorrow’s forest.

In daily life, Monism teaches us to establish a “Holistic view.” Stop separating your psychological stress from your physical fatigue (mind-body monism); stop feeling that sacrificing the environment for profit has nothing to do with you (ecological monism); stop using extreme polarities (black-and-white, friend-or-foe) to tear apart interpersonal relationships. When you realize that “harming others or the environment is essentially harming yourself,” you can liberate yourself from narrow egocentrism and attain a profound tranquility—breathing and sharing a destiny with the entire world.
