I would have to vote for liberty.
When the questions, "Why are we here?" and "What should we do now?" are raised in any instance of a society holding power, which all mobs do by their nature, it is one thing when those questions are raised in the context of the local example of a society and its rightful sphere of influence, and it is another thing when those questions are raised in the context of a non-existing monolithic Society. Are the people free to disagree? To disassociate? To the degree they are, the danger is non-existing; as here, on this polite board.
Asking such questions allows society to advance. The implication is meant to be a good one, that life for all the atoms sometimes improves as the result of collective actions. Yet, that is only sometimes true, not automatically true, based simply on the asking of the questions.
I think it can be argued that societies are allowed to advance and do advance in an environment in which the atoms collectively agree to defend each other from the overwhelming power of every other, America being an example of that concept. Even in its imperfect 3/4 start American limited constitutional republican democracy is all about limiting the power of the mob, and is cornerstoned on an individual bill of rights.
It's just that, we atoms are atoms of imperfect naked sweaty apes, and the urge to access the irresistable power of the mob/we is often too much to resist. Imagine all the good 'we' could do, if only 'we' could harness the power of the entire mob, and direct it?
We do that, even in the context of an American experiment; the War in Iraq is an example, and there are atoms in some indirect sense 'supporting' that War that do not with every fibre of their being wish to support that War at all. Yet, this is an inevitability, as on every course of action or inaction, it is not possible to simultaneously both act and to not act. Under such circumstances, it is best to permit a fracturing of 'society' into societies that support the action, and societies that do not, and do the best we can to not trounce on each other.
