The freedom to engage in entrepreneurship, and the benefits that entrepreneurs create for all of us, are the main theme of this group of previously published Freeman essays, which includes short pieces by Ludwig von Mises and Israel Kirzner among other well-known names. A number of contemporary authors have contributions here as well. The essays show how risk-taking and creativity are the key to economic progress and for providing life’s necessities at progressively lower prices and higher quality. Several essays rightly predict the ways that computerization might change the worlds of work and family.
