Baruch Spinoza’s Ethics: What Does It Really Mean to Live Ethically?
The Obedient Life We Never Questioned
We praise the person who follows the rules. The employee who never questions a directive, the citizen who defers to authority, the believer who suppresses doubt—these are the figures our culture rewards with the word "ethical." Morality, we have been taught, is fundamentally about obedience: obedience to God, to law, to social convention. To be good is to restrain yourself.
But what if this entire architecture of virtue is built on a misunderstanding? What if the very act of obedience, performed without understanding, is not morality at all but merely a more sophisticated form of servitude?
This is the provocation that Baruch Spinoza (1632–1677) inscribed into one of the most dangerous books in the history of Western thought: Ethica, ordine geometrico demonstrata—the Ethics, Demonstrated in Geometrical Order, published posthumously in 1677.
A Philosopher Forged in Exile
To understand why Spinoza had to write the Ethics, one must first understand what was taken from him. In July 1656, the young Spinoza was issued a herem—the harshest excommunication ever pronounced by the Portuguese-Jewish community in Amsterdam. He was twenty-three. The decree forbade any person from communicating with him, reading his writings, or standing within six feet of his body. He would spend the rest of his life grinding lenses for a living, while quietly constructing a philosophical system that would shake the foundations of European theology.
The Ethics was Spinoza’s answer to a world that demanded blind submission. Written between 1661 and 1675 in the austere language of Euclidean geometry—definitions, axioms, propositions, demonstrations—this was not a plea for tolerance. It was a radical dismantling of the very concept that morality requires an external lawgiver.
God Is Not Watching: The Revolution of Deus sive Natura
The cornerstone of Spinoza’s Ethics is a claim so audacious that it earned him the label "atheist" for centuries: Deus sive Natura—God, or Nature. God is not a transcendent judge who dispenses commandments from beyond the sky. God is the infinite, self-causing substance of which all things—rocks, rivers, human minds—are modes or expressions.
If God and Nature are one, then the moral framework built upon divine reward and punishment collapses entirely. There is no cosmic tribunal. There is no afterlife where accounts are settled. The universe operates not by will but by necessity, and to call one arrangement of matter "good" and another "evil" is merely to project human appetite onto an indifferent cosmos.
This is not nihilism. It is the precondition for a genuinely liberated ethics.
Conatus: You Are Already Striving
If morality is not obedience, then what is it? Spinoza’s answer arrives in Part III of the Ethics, in one of the most consequential sentences in the history of philosophy:
The conatus with which each thing endeavors to persist in its own being is nothing but the actual essence of the thing itself. — Baruch Spinoza, Ethics, Part III, Proposition 7 (1677)
Conatus—the striving to persevere in one’s own being—is not a moral duty imposed from without. It is what you already are. Every organism, every mind, every configuration of nature expresses a drive to sustain and enhance its own existence. Ethics, for Spinoza, is not about suppressing this drive in the name of duty. It is about understanding it—and thereby increasing our power to act freely.
Here the layers of the concept unfold. Conatus is not mere biological survival. When the mind achieves adequate ideas—when it understands the true causes of things rather than clinging to confused images—its power of thinking expands. Joy, in Spinoza’s precise vocabulary, is the passage from a lesser to a greater perfection. Sadness is the reverse. To live ethically is to live in such a way that one’s capacity for understanding, and therefore for joy, continually increases.
The Wellness Industry and the Betrayal of Conatus
Now turn this lens on our present moment. The contemporary wellness industry speaks relentlessly of "self-care" and "self-improvement." Yet what it typically offers is a menu of passive consumption: supplements, meditation apps, productivity hacks, curated routines designed to make you a more efficient unit within the very system that exhausted you in the first place. The conatus is hijacked: the striving to persevere becomes the striving to perform.
Spinoza would recognize this as a form of what he called servitude—bondage to passions we do not understand. When we obey an algorithm that tells us how to feel, when we measure our worth by metrics invented by someone else’s profit motive, we are not exercising conatus. We are surrendering it. The Ethics insists that genuine well-being cannot be purchased or prescribed. It can only be achieved through the difficult, sometimes painful labor of understanding—understanding ourselves, our affects, and the structures that shape them.
From Solitary Striving to Collective Reason
Yet Spinoza was no apostle of rugged individualism. Part IV of the Ethics makes an astonishing claim: nothing is more useful to a human being than another human being who lives according to reason. The conatus of each individual is not diminished but amplified through rational community. When people come together not through fear or obedience but through shared understanding, they form what Spinoza called a society governed by reason—a polity in which each person’s flourishing strengthens the whole.
This is a vision of solidarity that needs no external lawgiver, no threat of punishment, no promise of heaven. It is grounded in the recognition that my capacity to understand is inseparable from yours, that the structures which diminish your power of thinking inevitably diminish mine. In an age when loneliness has been declared a public health emergency and political life is poisoned by manufactured fear, Spinoza’s rational solidarity is not a historical curiosity. It is an urgent blueprint.
Spinoza spent his life grinding lenses—shaping glass so that others might see more clearly. The Ethics is itself a lens, one that asks us to stop obeying and start understanding. The question it leaves with us is devastatingly simple: Are you living according to what you understand, or according to what you have been told to believe?
I would be grateful to hear your answer.
