This is why I support the idea of Free Culture. Obviously Thomas Jefferson was not writing with culture in mind, but I do think he deliberately chose wording that could be applied in a wide variety of situations. The Free Culture idea is all about liberty and the pursuit of happiness: the liberty to take and reuse the culture that has been forced upon us. Disney did not ask my permission to inject Mickey Mouse images into my mind. Nor did Warner Brothers, Bad Robot, or the Blender Foundation (gotta include some good guys in this list!). If they force their culture on me, it becomes my culture. I will use it as such.
This quote – I don’t know how I originally found it – is one of the reasons why I got into Open Source. I remember, several years ago, printing it out and putting it above my bed so I would always have this reminder of why a good person does what he/she/xe does.
