Auguste Comte (full name Isidore Marie Auguste François Xavier Comte) (January 17 (recorded January 19), 1798 - September 5, 1857) was a French thinker who coined the term sociology. He is remembered for being the first to apply the scientific method to the social world.
One universal law that Comte saw at work in all sciences he called the 'law of three phases'. It is by his statement of this law that he is best known in the English-speaking world; namely, that society has gone through three phases: Theological, Metaphysical, and Scientific. He also gave the name "Positive" to the last of these because of the polysemous connotations of the word.
