This song is clearly a reference to George Orwell's 1984, in which the citizens of the totalitarian government wheren't even allowed to have a single thought that wasn't censored. This relates where he states "in this time of free thought it'd be a shame to let it rot open up your mind and let some thought inside use your head, for what it's there for." Basically, he is saying that it's a shame that people don't use their minds in a free society like ours because if they were forced to live in a society where thought was not allowed, they'd be struggling against such a restriction.
