Auguste Comte

Positivist · Europe · 1798 to 1857

French thinker who held that knowledge should rest on observed facts, and who proposed a science of society.

What it is

Auguste Comte (1798 to 1857) was a French thinker, born in Montpellier, who founded positivism and gave sociology its name. His central idea is that the study of the world and of society should rest on observed facts and scientific laws, and not on speculation about causes beyond experience.

He worked out a philosophy of mathematics, physics, chemistry and biology in turn, and then sought a science of society. Later in life he proposed a Religion of Humanity, which many of his admirers did not follow. He held that the progress of knowledge and the order of society belong together, and that a science of society would help humankind to function as one.

The main ideas

  • Positivism. Genuine knowledge comes from observation and the laws that relate observed facts, not from searching for hidden essences or first causes.
  • Three stages. Human thought, and societies with it, pass through three stages: the theological, the metaphysical and the positive, in which science governs.
  • A hierarchy of the sciences. The sciences form an ordered series, from mathematics up to the study of society, each resting on those before it.
  • Sociology and altruism. He called the science of society sociology, and urged that people live for the sake of others, a view for which he coined the word altruism.

What it looks like in practice

Picture someone trying to understand why a town's economy collapsed. Comte would ask them to set aside explanations in terms of fate or hidden forces and look for regular patterns in observed facts, in the way a scientist studies any other part of nature. The aim is not only to explain what happened, but to learn from regular patterns how a society could be arranged better, so that knowledge of society becomes a guide to improving it, as knowledge of nature guides engineering and medicine. This is an illustration of the idea, not a quotation.

Books and moments

  • The Course of Positive Philosophy is his large work setting out positivism and the sciences.
  • The System of Positive Polity is his later work on society and the Religion of Humanity.

Questions and criticism

  • Can society be studied like nature? His claim that human affairs follow discoverable laws has been supported and strongly doubted.
  • Is the three-stage story true? The idea that thought advances in neat stages is thought too simple by many historians.
  • Why a religion of humanity? His late turn to a secular religion is seen by some as a natural extension and by others as a break with his own method.

Close neighbours

He worked with Saint-Simon early on, and Mill engaged with his ideas. The pages on Mill and Hume show related thinking about experience and knowledge.
