On the other hand, you wouldn't get very far if you decided that no part of your life could be dictated by society. You'd die before you'd worked it all out from first principles. Unless you were some sort of magical wizard, what has magic and stuff. Then you might be ok. Though I bet you wouldn't, cos it would all have to be new magic and you would have to think of it really fast, like in three days cos you can't accept just anyone's say so about the whole water/thirst thingy and stuff. That water might be poison. So you'd have to be a really powerful wizard to make all new stuff that works without the imposition of society so that you can be truly free before you die of thirst. Though I guess if you were a really powerful wizard you might not get thirsty anyway, so it might not matter.
