Robert Nozick was a professor of philosophy at Harvard University who is most famous for his contributions to political philosophy. His 1974 book Anarchy, State, and Utopia helped establish the classical liberal or libertarian perspective as a viable alternative to redistributive egalitarian liberalism and to socialism. Despite many philosophers’ disagreements with Nozick’s arguments, those arguments could not be ignored.

No single individual is ever the sole founder of any major stance in political philosophy. Nevertheless, if one were forced to name the founder of the classical liberal perspective in political thought which holds as its primary political principle that individual liberty is to be respected and protected, one would have to point to the English philosopher John Locke.

Ronald Coase (1910-2013) was one of the most influential economists of the 20th century. His influence is due largely to two publications, the only two cited in the announcement of his Nobel Prize: The Nature of the Firm (1937) and The Problem of Social Cost (1960). These two articles are among the most-cited works in economics.

The political ideas that fully came together under the name “liberal” in the early 19th century—the ideas we often now refer to as “classical liberalism”—emerged out of major debates and developments from the late 1600s to the late 1700s. These were part of the broad European intellectual movement of that era that came to be known as “the Enlightenment".

The thinkers discussed in this volume are a remarkably diverse group. They were born in the 18th, 19th, and 20th centuries, and their work extends into the 21st. Some are economists primarily addressing other scholars, others popular writers aiming at the general public. Their educational backgrounds range from entirely informal schooling to PhDs from major universities.

When economists are called “influential,” it usually means they’ve changed the way other economists think. By that standard, Milton Friedman was one of the most influential economists of all time.

The oldest of nine children, John Stuart Mill was born on May 20, 1806; he died in France, where he spent many of his later years, on May 7, 1873. Mill had a very extraordinary, strenuous education, overseen by his ambitious father James, who believed that one becomes improved via education and, once educated, that is the end of the matter. John Mill was reading Greek at age three and Latin at the age of eight

Joseph Schumpeter is one of the most accomplished economists of the 20th century. Included among his many contributions is his path-breaking work on entrepreneurship—one of the quintessential characteristics of all market economies.

David Hume (1711–1776) is a towering and intriguing figure. He was the preeminent philosopher in what is now called the Scottish Enlightenment, a time that was “crowded with genius” and in a place regarded as the rebirth of the golden era of Athens. His writing displayed an astonishing range, addressing everything from metaphysics to politics, and in subject after subject, he produced fresh, novel, and brilliant insights.

The second edition of the fun and fascinating guide to the main ideas of the Austrian School of economics, written in sparkling prose, especially for the non-economist. Gene Callahan shows that good economics isn't about government planning or statistical models - it's about human beings and the choices they make in the real world. This may be the most important book of its kind since Hazlitt's Economics in One Lesson. Though written for the beginner, it has been justly praised by scholars too, including Israel Kirzner, Walter Block, and Peter Boettke.
