11. logic/reason vs. emotion

The whole saying, "listen to your heart" is dumb to me. I find that logic and reasoning is way more reliable for support than emotion. Your heart does not control all of your thoughts and ideas does it? No, your brain does. So why would someone 'listen' to a red organ that pumps blood instead of a huge system that controls your entire body and thoughts? Logic and reason can win a trial in court, while emotion cannot. Sure, you can be passionate about the case, but what good is that passion if you have no reasoning to back it up? When some people use emotion to solve a problem or make a decision, it is not really there heart, but more of a selfish decision. Anyone can say that their heart told them one way was better than another or that their heart guided them to do something, but if you think through a situation logically, you are more likely to make the better decision because of the pros and cons that would come out while you thought about it. For support purposes, logic and reason are going to be more believable than emotion. For example, you are trying to support your choice to get a lip ring. If someone were to take the 'emotion' route, they would say something like, "I REALLY want it, it looks so cool and I can tell it is the right thing for me to do!" Now who has parents that would fall for that? No one? At least close to no one. If you were to approach the topic more logically, you could say, "Mom, Dad, I have thought about it and weighed the situation and I think I could handle it. We could look up some information online and see the best way to go about it. I could pay for it and take care of it, and if we end up not liking it, well then we can just take it out and pretend like it never happened." If you were a parent, which route would you most likely appreciate better and listen to? The logic one right?
