Claude Henri Saint-Simon (1760-1825) was a positivist who believed that the study of
social phenomena should employ the same scientific techniques as the natural
sciences. But he also saw the need for socialist reforms, especially
centralized planning of the economic system.
Auguste Comte (1798-1857) coined the term "sociology." Like
Saint-Simon, he believed the study of social phenomena should employ scientific
techniques. But Comte was disturbed by the chaos of French society and was
critical of the Enlightenment and the French Revolution. Comte developed an
evolutionary theory of social cahange in his law of the three stages. He argued
that social disorder was caused by ideas left over from the idea systems of
earlier stages. Only when a scientific footing for the governing of society was
established would the social upheavals of his time cease. Comte also stressed
the systematic character of society and accorded great importance to the role
of consensus. These beliefs made Comte a forerunner of positivism and reformism
in classical sociological theory.
Emile Durkheim (1858-1917) legitimized sociology in France and became a dominant force
in the development of the discipline worldwide. Although he was politically
liberal, he took a more conservative position intellectually, arguing that the
social disorders produced by striking social changes could be reduced through
social reform. Durkheim argued that sociology was the study of structures that
are external to, and coercive over, the individual; for example, legal codes
and shared moral beliefs, which he called social facts. In Suicide he
made his case for the importance of sociology by demonstrating that socialfacts could cause individual behavior. He argued that societies were held
together by a strongly held collective morality called the collective
conscience. Because of the complexity of modern societies, the collective
conscience had become weaker, resulting in a variety of social pathologies. In
his later work, Dukheim turned to the religion of primitive societies to
demonstrate the importance of the collective consciousness.
