Reason and Desire

I think Dostoyevsky puts a lot of truth behind most of his statements. Better said, there is a lot of truth in them, he does not put them there, that would just be weird. Anyways, it seems that most of our desires are impulsive, and quite frankly, extremely irrational. Nevertheless, being the strange creatures that we are we do not care about this irrationality at all. We literally do not even give it a millisecond of a thought sometimes, while other times we recognize it fully and decide to just not care. Maybe we do this because our sense of rationality is not as grounded into us as the leaders of society and religion would like to think.
In this nonexistent perfect world, we would have full rationale. By full rationale, I mean one that we would actually pay attention to. The problem with this though, is that if we reason through everything, our desire will subside. Desires are a majority of the times unreasonable and reasoning will take them away. I would not like to live in a world like this. Honestly, what fun is there in life if the only thing you ever do is play by the rules? None, it is no fun. A lot of people find the statement "rules are meant to be broken" hard to believe, however, I think that the rules of reasoning truly are meant to be broken. Maybe that is another advantage in being able to say fuck it to the very things that threaten our lives: it allows us to enjoy.
