This is an essential primer of libertarian ideas starting with the premise that "Libertarianism is the view that each person has the right to live his life in any way he chooses so long as he respects the equal rights of others." David Boaz has, in a positive way, written an introduction to libertarian thinking. Starting with a brief history of the roots of libertarianism he puts forward libertarian principles in chapters highlighting the nature and source of individual rights, morals and ethics, toleration, the role of the constitution and law, and civil society and the economics of the free market. He shows how libertarians reject big government and deal with other current issues. The book concludes with a guide for further reading that provides the reader sources for more thorough information about libertarianism. I found this was one of the best introductions to the libertarian view of life that I have read.
