“I am a great admirer of Professor Hayek. Some of his books are absolutely supreme—“The Constitution of Liberty” and the three volumes on “Law, Legislation and Liberty”—and would be well read by almost every hon. Member.”

Principles of Legislation (1830), Ch. X : Analysis of Political Good and Evil; How they are spread in society
Context: It is with government, as with medicine. They have both but a choice of evils. Every law is an evil, for every law is an infraction of liberty: And I repeat that government has but a choice of evils: In making this choice, what ought to be the object of the legislator? He ought to assure himself of two things; 1st, that in every case, the incidents which he tries to prevent are really evils; and 2ndly, that if evils, they are greater than those which he employs to prevent them.
There are then two things to be regarded; the evil of the offence and the evil of the law; the evil of the malady and the evil of the remedy.
An evil comes rarely alone. A lot of evil cannot well fall upon an individual without spreading itself about him, as about a common centre. In the course of its progress we see it take different shapes: we see evil of one kind issue from evil of another kind; evil proceed from good and good from evil. All these changes, it is important to know and to distinguish; in this, in fact, consists the essence of legislation.

The Rights of the Colonists (1772)

1830s, The Lyceum Address (1838)
Context: Let every American, every lover of liberty, every well-wisher to his posterity swear by the blood of the Revolution never to violate in the least particular the laws of the country, and never to tolerate their violation by others. As the patriots of seventy-six did to the support of the Declaration of Independence, so to the support of the Constitution and laws let every American pledge his life, his property, and his sacred honor — let every man remember that to violate the law is to trample on the blood of his father, and to tear the charter of his own and his children's liberty. Let reverence for the laws be breathed by every American mother to the lisping babe that prattles on her lap; let it be taught in schools, in seminaries, and in colleges; let it be written in primers, spelling-books, and in almanacs; let it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice. And, in short, let it become the political religion of the nation; and let the old and the young, the rich and the poor, the grave and the gay of all sexes and tongues and colors and conditions, sacrifice unceasingly upon its altars. While ever a state of feeling such as this shall universally or even very generally prevail throughout the nation, vain will be every effort, and fruitless every attempt, to subvert our national freedom.

Amoureux et jaloux de la liberté humaine, et la considérant comme la condition absolue de tout ce que nous adorons et respectons dans l'humanité, je retourne la phrase de Voltaire, et je dis : Si Dieu existait réellement, il faudrait le faire disparaître.
Source: God and the State (1871; publ. 1882), Ch. II; Variants or variant translations of this statement have also been attributed to Bakunin:
The first revolt is against the supreme tyranny of theology, of the phantom of God. As long as we have a master in heaven, we will be slaves on earth.
A boss in Heaven is the best excuse for a boss on earth, therefore If God did exist, he would have to be abolished.
