"Freedom" only really has meaning in context. Freedom to do something, freedom not to have something done to you. On it's own it's an empty ideal.

Seeing as this is a programming board, I assume you mean "freedom" in a free software context, in which case my vote for free license goes to the MIT license. Simple and to the point, and not "copyleft" (which IMO is just trading one master for an arguably more benevolent one.)
