“Auguste Comte invented this word in 1851 as the deliberate opposite of egoism.”
In 1851, Auguste Comte published Systeme de politique positive and needed a word for the moral opposite of egoism. He built one from Italian altrui, an adjectival pronoun denoting belonging to others, which itself descended from the Latin phrase alteri huic, a dative construction meaning to this other person. Comte added the French suffix -isme and produced altruisme. The word reached English by 1853 through translations of his work.
The Latin ancestry is older than Comte realized. Alter, meaning the other in Latin, appears in Roman legal and philosophical texts from Cicero onward. It gave Italian altrui, and it also gave English words like alter, alternate, and altercation. The specific construction alteri huic, used in Roman legal texts as a dative phrase meaning to this other, was the precise ancestor Comte adapted into his neologism.
Comte's original sense was explicitly sociological and prescriptive. In his Religion of Humanity, altruism was not a description of behavior but a moral duty: living for others as the highest social obligation. Herbert Spencer and Charles Darwin adopted the term in the 1860s and 1870s, giving it a scientific dimension. By the time Darwin wrote about it in The Descent of Man in 1871, altruistic had shed most of its Comtean religious connotations and become a biological and psychological category.
The word's journey from French philosophical coinage to universal English psychological term happened in under fifty years. English dictionaries recorded altruistic by the 1870s. By the late 19th century, economists, psychologists, and evolutionary biologists were all using it in contexts Comte never imagined. The word is now one of those rare academic coinages that successfully migrated into common usage without losing its precision.

Altruistic now covers a range of behaviors from anonymous charitable giving to the self-sacrifice of emergency responders. Evolutionary biologists use it to describe cooperative behaviors in animals where one individual acts at cost to itself for the benefit of another. Economists use it in game theory to explain why people cooperate when defection would pay better. The word has proved remarkably durable, outlasting Comte's Religion of Humanity by more than a century.
What Comte wanted was a word that made moral seriousness possible without religious premises. What he gave us was a term useful precisely where he did not expect it: in laboratories studying ants, in psychological experiments on anonymity and giving, in debates about market failure. The word is now so common that most users have no idea it was invented by one man in one book. The best moral vocabulary is the kind you forget was invented.
