On Sacred Liberty, and Authority

Is liberty sacred? Anyone indoctrinated under the current worldview would I suppose, like the Aztec’s belief in human sacrifice, will either explicitly or implicitly agree with this belief. But what do we mean when we say liberty? This is towards a question I believe I've asked already, but what do we mean when we say we’re free? Free do what, exactly? Whatever we want, is the oft-given answer. Free to follow our animal instincts, obviously – or, if we’re rational actors – if we’re machines – we’ll work towards reasonable ends. But who thinks like a machine? Who wants to think like a machine? More importantly, is a machine ever free? This is the key point.
