Jacques Maritain (18 November 1882 – 28 April 1973) was a French Catholic philosopher. Raised as a Protestant, he converted to Catholicism in 1906. An author of more than 60 books, he helped to revive St. Thomas Aquinas for modern times and is a prominent drafter of the Universal Declaration of Human Rights. Pope Paul VI presented his "Message to Men of Thought and of Science" at the close of Vatican II to Maritain, his long-time friend and mentor. Maritain's interest and works spanned many aspects of philosophy, including aesthetics, political theory, the philosophy of science, metaphysics, education, liturgy and ecclesiology.

Maritain was born in Paris, the son of Paul Maritain, who was a lawyer, and his wife Geneviève Favre, the daughter of Jules Favre, and was reared in a liberal Protestant milieu. He was sent to the Lycée Henri-IV. Later, he attended the Sorbonne, studying the natural sciences; chemistry, biology and physics.

At the Sorbonne, he met Raïssa Oumançoff, a Russian Jewish émigré. They married in 1904. A noted poet and mystic, she participated as his intellectual partner in his search for truth. Raissa's sister, Vera Oumançoff, lived with Jacques and Raissa for almost all their married life.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
