“Freedom as an absolute does not exist since there are always constraints: genetic predetermination, surrounding environment, the society in which you live and, in the end, everything. Freedom is always a matter of degree: you cannot wish for the freedom to flap your arms and fly so long as gravity exists, nor can you wish for the freedom to breathe water. You are of course free to try both, but the results of such endeavours are not within your power. This is the big problem with freedom when it is taken up by some political ideology, for those who rely on the term are often trying to adjust the parameters of reality, and they simply cannot. And, when the revolutionary cries that he is fighting for “freedom,” be sure to go running away from him just as fast as you can, for you can be damned certain he’s fighting for the freedom to tell you what to do.”
