“Man has rights because they are natural rights. They are grounded in the nature of man: the individual's capacity for conscious choice, the necessity for him to use his mind and energy to adopt goals and values, to find out about the world, to pursue his ends in order to survive and prosper, his capacity and need to communicate and interact with other human beings and to participate in the division of labor.”

“It is infinitely better to rely on the pursuit of economic interest by landowners or street companies than to depend on the dubious “altruism” of bureaucrats and government officials.”

“Of all the numerous forms that governments have taken over the centuries, of all the concepts and institutions that have been tried, none has succeeded in keeping the State in check.”

“The greatest danger to the State is independent intellectual criticism.”

“No action can be virtuous unless it is freely chosen.”

“To be moral, an act must be free.”

“It is no crime to be ignorant of economics, which is, after all, a specialized discipline and one that most people consider to be a ‘dismal science.’ But it is totally irresponsible to have a loud and vociferous opinion on economic subjects while remaining in this state of ignorance.”

“Capitalism is the fullest expression of anarchism, and anarchism is the fullest expression of capitalism. Not only are they compatible, but you can't really have one without the other. True anarchism will be capitalism, and true capitalism will be anarchism”

“It’s true: greed has had a very bad press. I frankly don’t see anything wrong with greed. I think that the people who are always attacking greed would be more consistent with their position if they refused their next salary increase. I don’t see even the most Left-Wing scholar in this country scornfully burning his salary check. In other words, "greed" simply means that you are trying to relieve the nature given scarcity that man was born with. Greed will continue until the Garden of Eden arrives, when everything is superabundant, and we don’t have to worry about economics at all. We haven’t of course reached that point yet; we haven’t reached the point where everybody is burning his salary increases, or salary checks in general.”

“Libertarianism holds that the only proper role of violence is to defend person and property against violence, that any use of violence that goes beyond such just defense is itself aggressive, unjust, and criminal”

“Once one concedes that a single world government is not necessary, then where does one logically stop at the permissibility of separate states? If Canada and the United States can be separate nations without being denounced as in a state of impermissible ‘anarchy’, why may not the South secede from the United States? New York State from the Union? New York City from the state? Why may not Manhattan secede? Each neighbourhood? Each block? Each house? Each person?”
