The Ethics of Becoming Useful to Others

Why rational people seek friendship, cooperation, and mutual strengthening.

I.

Selfishness has a bad name in moral philosophy, and for good reason. The selfish person who exploits others, who treats relationships as transactions, who views cooperation as weakness, is a familiar and unattractive figure. But Spinoza argues that genuine self-interest, understood adequately, leads to the opposite of exploitation. It leads to cooperation, friendship, and the active desire to be useful to others.

The reasoning is geometric. A human being's power to act is increased by the presence of other human beings who are themselves powerful. Isolation diminishes power, because a solitary person can do less than a coordinated group. Hostility diminishes power further, because energy spent fighting others is energy not spent on constructive activity. Therefore, the rational person seeks the company of others who are rational, because their rationality increases his own.

II.

This is not altruism in the sense of self-sacrifice. It is the recognition that self-interest and other-interest converge when both are understood adequately. The farmer who helps his neighbor build a barn is not sacrificing his interest to the neighbor's. He is investing in a relationship that will yield returns when he needs help with his own harvest. The investment is rational, not charitable.

But Spinoza goes further. The rational person does not merely cooperate instrumentally. He finds joy in the flourishing of others, because he understands that their flourishing is connected to his own. The joy is not a calculation. It is an affect, but it is an affect grounded in an adequate idea: the idea that human beings are more powerful together than apart.

III.

The ethics of becoming useful to others has a practical dimension that is often neglected. To be useful, you must be capable. A person who has nothing to offer cannot be useful, no matter how good his intentions. The cultivation of personal capacity (skill, knowledge, emotional stability, material resources) is therefore a moral obligation, because it increases your ability to benefit others.

This is the opposite of the self-abnegation that some moral traditions recommend. Spinoza does not tell you to diminish yourself so that others may rise. He tells you to increase yourself so that your increase can be shared. The strong person who helps others is a force for good. The weak person who sacrifices what little he has for others is a double loss: his own power is diminished, and the help he can offer is minimal.

IV.

The social dimension of usefulness is equally important. A society of useful people is a society in which cooperation is the default. A society of useless people is a society in which dependence, resentment, and conflict are the defaults. The difference is not a matter of moral exhortation. It is a matter of conditions that produce capable or incapable citizens.

This is why Spinoza's political philosophy emphasizes education, freedom of thought, and the creation of institutions that increase individual power. A state that wants useful citizens must invest in the capacities of its people. A state that neglects education, that suppresses thought, that keeps its population weak in order to keep it governable, is a state that is manufacturing uselessness, and it will pay the price in diminished collective power.

V.

The ethics of becoming useful to others culminates in the ideal of friendship among the wise. The free person seeks the company of other free people, not because he needs them in a dependent sense, but because their presence increases his joy and his power. Their understanding amplifies his understanding. Their serenity reinforces his own. The friendship is not based on need but on shared strength.

This is the highest form of human relationship, in Spinoza's view, and it is the natural outcome of a life governed by reason. The person who understands himself adequately understands that others are not threats to his power but potential sources of its increase. The pursuit of usefulness is not a sacrifice. It is a strategy, and the strategy works because human beings are modes of a single substance, connected by the causal order that makes their flourishing interdependent.
