Are humans cooperative or competitive in the state of nature? Philosophical and empirical angles.

Did you know that one of the strongest pieces of evidence for ancient human cooperation is a 15,000-year-old femur bone that had been broken and then healed? In the wild, a broken leg is a death sentence because you cannot hunt or flee. A healed femur proves that someone stayed with the injured person, bound the wound, and fed them until they recovered. This suggests that our "natural" state might be defined more by a bandage than a spear. ## The Philosophical Battle: Hobbes vs. Rousseau The debate over our "state of nature"—the hypothetical condition of humanity before organized government—is dominated by two opposing thinkers. Thomas Hobbes, writing in his 1651 masterpiece [*Leviathan*](https://en.wikipedia.org/wiki/Leviathan_(Hobbes_book)), argued that humans are inherently selfish and driven by a "perpetual and restless desire of power after power." Without a strong central authority to keep us in check, he believed we would descend into chaos. > "In such condition, there is no place for industry... no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short." A century later, [Jean-Jacques Rousseau](https://plato.stanford.edu/entries/rousseau/) offered a counter-narrative in his *Discourse on Inequality*. He imagined the "noble savage" as peaceful and self-sufficient, arguing that it was the invention of private property and "civilization" that introduced greed and conflict. To Rousseau, we are born cooperative, but society corrupts us. ## The Empirical Reality: Evolution and Mutual Aid Modern science suggests the truth is a complex mix of both. Biologists like [Frans de Waal](https://www.ted.com/talks/frans_de_waal_moral_behavior_in_animals) have shown that primates—our closest relatives—display deep-seated tendencies for empathy and fairness. In his book [*Mutual Aid: A Factor of Evolution*](https://en.wikipedia.org/wiki/Mutual_Aid:_A_Factor_of_Evolution), the naturalist Pyotr Kropotkin argued against the "survival of the fittest" as a purely competitive struggle. He observed that species which learn to cooperate often have a better chance of survival than those that are constantly at war with one another. However, humans are also "groupish." We are hyper-cooperative with our "in-group" (our tribe or family) but can become intensely competitive or even violent toward "out-groups." This is known as **parochial altruism**. We evolved to cooperate in order to compete more effectively as a unit. ## The Synthesis We aren't strictly "good" or "bad" by nature. Instead, we are **strategically social**. We possess the biological hardware for extreme kindness and extreme cruelty, and which one we use depends heavily on our environment and our perceived safety. *** **Explore Further:** 1. If humans are naturally cooperative within groups, does the existence of modern "nations" help us scale that cooperation, or does it just create larger, more dangerous "out-groups"? 2. How does the **Prisoner's Dilemma** in [Game Theory](https://plato.stanford.edu/entries/game-theory/) explain why two selfish people might choose to cooperate even when it seems risky? 3. If Rousseau was right that society "corrupts" us, would it even be possible to return to a simpler, more cooperative way of living in a world of 8 billion people?

Imagine you are standing in a wild, unclaimed forest and you spot a bush heavy with ripe blackberries. According to Thomas Hobbes, you would have to fight everyone else for those berries. According to Jean-Jacques Rousseau, you’d pick them peacefully and move on, never thinking of "owning" the bush. **John Locke** offers a third way. In his 1689 work, [*Two Treatises of Government*](https://en.wikipedia.org/wiki/Two_Treatises_of_Government), Locke argued that the state of nature is neither a bloodbath nor a selfless utopia. Instead, it is a place of **ordered liberty** governed by human reason. ## A State of Liberty, Not License Locke believed that even without a government, humans are bound by a "Law of Nature." This isn't a physical law like gravity, but a moral law discovered through reason. He argued that because we are all equal, no one has the right to harm another's life, health, liberty, or possessions. > "The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind... that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions." While Hobbes saw humans as driven by fear, Locke saw us as naturally capable of following a moral compass. To Locke, we aren't "nasty and brutish"; we are generally reasonable neighbors who occasionally have "inconveniences" or disagreements. ## The Magic of Labor: How "Mine" Begins One of Locke’s most influential ideas is the **Labor Theory of Property**. He asked: How does a person come to own something in a world that was originally given to all of us in common? His answer was simple: **Labor**. When you pick those blackberries in the forest, you have mixed your physical effort (your labor) with the fruit. Because you own your body and your effort, the fruit becomes yours. This "mixing" creates a natural right to property before any government ever exists. However, Locke added a famous condition known as the **Lockean Proviso**: you can only claim property if there is "enough, and as good, left in common for others." You can’t pick every single berry and let them rot while others starve. ## Why Bother with Government? If the state of nature is mostly peaceful and reasonable, why would we ever leave it? Locke argued that we create a **Social Contract** to solve the "inconveniences" of being our own judges. 1. **Lack of an established law:** People might disagree on how the Law of Nature applies to a specific fight. 2. **Lack of an impartial judge:** If someone steals your berries, you might be too angry to decide on a fair punishment. 3. **Lack of enforcement:** You might not be strong enough to get your property back on your own. For Locke, the government isn't a terrifying master (like Hobbes's *Leviathan*); it’s more like a **hired referee**. Its only job is to protect the "natural rights" we already had in the state of nature. If the referee stops being fair, Locke famously argued that the people have a [right to revolution](https://plato.stanford.edu/entries/locke-political/#Revo).

The social contract isn't just an old dusty agreement between kings and peasants; it is the invisible software running our modern world. While Hobbes and Rousseau argued over whether we are naturally "good" or "bad," modern thinkers have taken the concept into much weirder and more provocative territory. ### 1. The Veil of Ignorance: Fairness as a Thought Experiment Imagine you are about to be born, but you have no idea who you will be—you could be a billionaire, a person with a disability, a minority, or a genius. What laws would you write? **John Rawls**, one of the most influential political philosophers of the 20th century, introduced this "Original Position" in his book [*A Theory of Justice*](https://en.wikipedia.org/wiki/A_Theory_of_Justice). He argues that a truly just social contract can only be designed if we step behind a "Veil of Ignorance." This rabbit hole shifts the conversation from "how did society start?" to a practical mathematical question: how do we ensure the person at the bottom of the ladder still has a life worth living? ### 2. The Racial Contract: The Agreement to Exclude What if the social contract wasn't a universal agreement for "humanity," but a private club where some people were never invited to sign? **Charles Mills**, in his groundbreaking work [*The Racial Contract*](https://en.wikipedia.org/wiki/The_Racial_Contract), argues that traditional philosophy ignores a dark reality: the "contract" was often an agreement between one group of people to exploit another. This perspective provides a "glitch in the matrix" moment, forcing you to ask if our current laws are actually neutral or if they are simply a continuation of an older, exclusionary deal. > "The Social Contract is not a contract between everybody ('we the people'), but between some people (white people) over other people (non-white people)." — Charles Mills ### 3. The Prisoner’s Dilemma: The Math of Trust Why do we follow the rules even when no one is looking? It might not be because we are "good," but because of a mathematical trap. **Game Theory** uses the [Prisoner's Dilemma](https://en.wikipedia.org/wiki/Prisoner%27s_dilemma) to show why two rational people might not cooperate, even if it seems in their best interest to do so. Exploring this reveals why social contracts are so fragile. It introduces the concept of "Tit-for-Tat"—the idea that cooperation only survives if we have a way to punish cheaters. Robert Axelrod’s book [*The Evolution of Cooperation*](https://en.wikipedia.org/wiki/The_Evolution_of_Cooperation) is the essential guide here, proving that "niceness" can be a winning biological strategy. ### 4. The Right of Exit: Can You Unsubscribe? If you never signed a physical piece of paper when you were born, why are you bound by the laws of your country? This rabbit hole explores the concept of **Tacit Consent**. Philosophers like John Locke argued that by using the roads and enjoying police protection, you have "signed" the contract with your feet. However, modern "Seasteaders" and "Sovereign Individuals" are looking for ways to opt out entirely by creating new societies on international waters or in digital spaces. Exploring the work of [Robert Nozick](https://en.wikipedia.org/wiki/Robert_Nozick) in *Anarchy, State, and Utopia* challenges the idea that the state has a monopoly on your life just because you happen to be standing on its dirt.
