What is libertarianism? This is the political philosophy that asks but one question, and gives but one answer. The question? When is force or the threat of force justified? The answer? Only in response to, in defense from, or in retaliation against the prior use of violence against a person or his legitimately owned property.

And what is its source? How does virgin territory properly become converted into private property? Again libertarianism is succinct: through homesteading and any subsequent legitimate form of title transfer.

Homesteading consists of mixing your labor with the land or other unowned parts of nature, and property may be legitimately transferred from one person to another through any voluntary nonfraudulent means: sale, gift, barter, trade, gambling, inheritance, etc.

Walter Block's daring, funny, iconoclastic Defending the Undefendable is a libertarian classic. In this sequel, Block defends even more of society's hidden heroes, those unfairly maligned entrepreneurs, workers, and capitalists who create value through free and voluntary interaction, and he does it in the same colorful and engaging style. (Peter G. Klein)

"Walter Block has assembled 30 chapters defending behavior that is probably offensive to most Americans, such as dwarf tossing and stereotyping, and many that are downright illegal, such as dueling and smuggling. Plus, he's provided us with humorous cartoons at the end of many chapters. The bottom line message in Freedom in All Realms: Defending the Undefendable is that the true test of our commitment to personal liberty doesn't come when we permit others to engage in those peaceable, voluntary acts with which we agree. It comes when we permit others to engage in peaceable, voluntary acts we find offensive." (Walter E. Williams)

In an age when all too many people run for cover when their controversial neighbors evoke the ire of intellectual elites, Walter Block heroically comes to the rescue. You don't have to agree with him on everything to respect his thoughtfulness on behalf of the unpopular and the misunderstood. Liberty's very survival depends upon such courage! (Lawrence W. Reed)

Walter Block is the most courageous of libertarian economists. No issue is too tough for the application of solid principles-and that makes him unique. I find him to be absolutely consistent in his logic, clear enough for anyone to grasp, and bold enough to take on any and all challengers. On top of it all, he's provocative and fun to read.

"Defending the Undefendable: Freedom in All Realms is a worthy, indispensable sequel to DTU, written in a fun, punchy, and accessible style, but with no punches pulled." (Stephan Kinsella)
