“Hayek’s essential political philosophy was that liberty is the supremacy of law. To some, this may appear a paradoxical conception of liberty, for liberty is too often considered to be the absence of law. This, however, was the exact opposite of Hayek’s view. He thought that liberty is not possible without law. Right law is liberty.”

R. v. Cobbett (1804), 29 How. St. Tr. 49.
Context: The law of England is a law of liberty, and, consistently with this liberty, we have not what is called an imprimatur (let it be printed); there is no such preliminary licence necessary. But if a man publish a paper, he is exposed to the penal consequences, as he is in every other act, if it be illegal.

Hayek's Journey: The Mind of Friedrich Hayek (2003)
Context: Hayek died in Freiburg, Germany, on March 23, 1992, less than two months shy of his ninety-third birthday. After 1985, he was unable to work and lost contact with almost all friends and associates. In his last years, almost the only people with whom he had regular contact were his wife, Helene; secretary Charlotte Cubitt, whom he always called “Mrs. Cubitt”; children Larry and Christine Hayek; and Bartley. Hayek was grateful to Cubitt for her assistance from 1977 to 1992. He inscribed in her copy of The Fatal Conceit in 1990: “In gratitude for all her help over so many years F. A. Hayek.”
During his last years, he had periods of more and less lucidity, as well as being ill and depressed. Lord Harris of the Institute of Economic Affairs wrote in his obituary of Hayek that “by 1989 the great man had lost touch with affairs.” He was buried in Vienna, the place of his birth.
[... ] Friedrich Hayek was the greatest political philosopher of liberty during the twentieth century.

King v. Wagstaffe (1665), Sir Thomas Ray. Rep. 138.

Source: The Law (1850)
Context: Life, faculties, production — in other words, individuality, liberty, property — this is man. And in spite of the cunning of artful political leaders, these three gifts from God precede all human legislation, and are superior to it. Life, liberty, and property do not exist because men have made laws. On the contrary, it was the fact that life, liberty, and property existed beforehand that caused men to make laws in the first place.
