Gun Control & RKBA

US Supreme Court Justice Anthony Kennedy explained this often forgotten sense of happiness in his 2005 lecture at the National Conference on Citizenship. Kennedy notes that while in modern times there is a “hedonistic component” to the definition of happiness, for the framers of the Declaration of Independence “happiness meant that feeling of self-worth and dignity you acquire by contributing to your community and to its civic life.” In the context of the Declaration of Independence, happiness was about an individual’s contribution to society rather than pursuits of self-gratification. While this sense has largely fallen out of use today, it’s important to keep these connotations of happiness mind when studying political documents from the 18th century.

Notice the "community" component of that definition.
