The human striving for improved and usually more pleasant conditions

"Life, Liberty and the pursuit of Happiness" is a well-known phrase in the United States Declaration of Independence. The phrase gives three examples of the "unalienable rights" which the Declaration says have been given to all human beings by their creator, and which governments are created to protect. There is debate about what the word "happiness" may have meant in 1776. Current usage focuses on pleasant, positive emotions and having needs satisfied, whereas in 1776 the common meaning may have been "prosperity, thriving, wellbeing".
