France France supported the Americans in their revolt against English rule and, in 1789, overthrew their own monarchy, with the cry of "Liberté, égalité, fraternité". The bloodbath that followed, known as the reign of terror, soured many people on the idea of liberty. Edmund Burke, considered one of the fathers of conservatism, wrote "The French had shewn themselves the ablest architects of ruin that had hitherto existed in the world." Ideologies Liberalism According to the Concise Oxford Dictionary of Politics, liberalism is "the belief that it is the aim of politics to preserve individual rights and to maximize freedom of choice". But they point out that there is considerable discussion about how to achieve those goals. Every discussion of freedom depends on three key components: who is free, what they are free to do, and what forces restrict their freedom. John Gray argues that the core belief of liberalism is toleration. Liberals allow others freedom to do what they want, in exchange for having the same freedom in return. This idea of freedom is personal rather than political. William Safire points out that liberalism is attacked by both the Right and the Left: by the Right for defending such practices as abortion, homosexuality, and atheism, and by the Left for defending free enterprise and the rights of the individual over the collective.

Their approach to implementing liberty involves opposing any governmental coercion, aside from that which is necessary to prevent individuals from coercing each other. Libertarianism is guided by the principle commonly known as the Non-Aggression Principle (NAP). The Non-Aggression Principle asserts that aggression against an individual or an individual's property is always an immoral violation of one's life, liberty, and property rights. Utilizing deceit instead of consent to achieve ends is also a violation of the Non-Aggression principle. Therefore, under the framework of the Non-Aggression principle, rape, murder, deception, involuntary taxation, government regulation, and other behaviors that initiate aggression against otherwise peaceful individuals are considered violations of this principle. This principle is most commonly adhered to by libertarians. A common elevator pitch for this principle is, "Good ideas don't require force." Republican liberty According to republican theorists of freedom, like the historian Quentin Skinner or the philosopher Philip Pettit, one's liberty should not be viewed as the absence of
