Revisiting the root of our ideas in freedom and liberty, Eric Mack argues that everyone has a claim to liberty because it represents the possibility to live a valuable life. With that being said, people believe in varying degrees of liberty, even libertarians. Mack believes that libertarians encompass a wide spectrum of thought ranging from classical liberal to anarchists.

What is libertarianism? What are the fundamental principles of justice? What is a political good? Are anarchists libertarians? Are classical liberals libertarians? Are all libertarians against coercion? Who is Herbert Spencer?
