Everyone knows the famous lines of the Declaration of Independence: “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” “Happiness” is actually mentioned again later as one of the objects for which government is instituted in the first place. But what exactly is “happiness” (and where in this formulation did “property” go?).

Here is a new book that explores the intellectual history of the subject: The Pursuit of Happiness: An Intellectual History (University of Missouri Press), by Carli N. Conklin.

“Scholars have long debated the meaning of the pursuit of happiness, yet have tended to define it narrowly, focusing on a single intellectual tradition, and on the use of the term within a single text, the Declaration of Independence. In this insightful volume, Carli Conklin considers the pursuit of happiness across a variety of intellectual traditions, and explores its usage in two key legal texts of the Founding Era, the Declaration and William Blackstone’s Commentaries on the Laws of England.

For Blackstone, the pursuit of happiness was a science of jurisprudence, by which his students could know, and then rightly apply, the first principles of the Common Law. For the founders, the pursuit of happiness was the individual right to pursue a life lived in harmony with the law of nature and a public duty to govern in accordance with that law. Both applications suggest we consider anew how the phrase, and its underlying legal philosophies, were understood in the founding era. With this work, Conklin makes important contributions to the fields of early American intellectual and legal history.”
