i believe that it is very natural, and instinctive for us to feel superiority over other people.
I'm not too sure what you mean by 'natural', do you mean common, or in our nature? Which can be taken generally, as in we all instinctively feel superiority over others, or it could be taken in relation to human beings as a trait that we all possess but don't necessarily use. Elaborate on this if you can. You say that it is instinctive for us to feel superiority, I cannot help but hear the connotation that you think it is good for us. I just want to make sure that I understand, since, most of our instinctive reactions have been shown to be bad ones. This is why we promote rational, logical, and patient thought. If we always acted on our instincts we would still be going around killing each other at the slightest hurt feeling, jumping our sexually desired people, stealing, etc. Ofcourse, some instincts are good, but the question here is whether feeling superiority over another is a good one. Personally, I don't think it is. In a democratic society with principles of equality, fairness, rights, etiquette, etc - it brings about situations of inequality, unfairness, violation of rights, and a corrosion of etiquette as well as the fabric of society. If we were still roaming around like monkeys in a jungle then I would agree that the instinct is good for us, because it would help us survive. In a society we survive better by feeling good about ourselves and by initiating teamwork.
I believe that this instinct comes from our undying need to be right.
I wouldn't say that we have an undying need to be right, I would say we have an undying need to feel safe. See, we feel safe when we assume we know things to be true. We feel very threatened when someone tells us we are wrong. If you have been going about talking to people your whole life assuming they actually like or care about you, it would really hurt to find out that they all hated you and only talked with you because you possessed something they wanted. But this is exactly where we must differ, human beings are smarter than that and we need to realize that the best way to life is an open minded one where you are open to any interpretation and a fair reflection on each one. Only this way can you present yourself with an adequate number of sources from which to logically and rationally choose from. Otherwise, you will be constricted to few sources without an indepth understanding and will come to have fallacious beliefs that become hardened over time. We must realize that Plato was right when he said he knew nothing, we all know nothing. Which is to mean that we can only do with the best we got, and if we want to have any kind of progress we have to stay open minded to different ideas which will all have their positives and negatives, but we must find a way to find their significance to our relative positions and make use of them.
I believe that the only "truth" in our world is one's own truth, and what one believes.
I couldn't agree more. But your truth is affected by your heuristics in life. If you constrict yourself to few views or ideas, your ideas will be meager at best. Making the best with what one has, means that one goes through as many sources as they can in order to find the truth about the thing. Keeping in mind that it will never be an absolute truth, one is left with a constant awareness of things and a curiosity that will last you a lifetime about the things in this world and the plethora of possibilities for each of them.
And the only reason this truth comes into doubt is because of the presence of other people, and essentially other "truths," which cast doubt on what we know, and prevent us from being fulfilled with the knowlege that we hold the truth.
The presence of other people isn't the ONLY reason ones truth comes into doubt. Experience is another, as is our own consciousness. Have you never had a thought that you found to be contradicting one of your other beliefs, but wasn't initiated because of the presence of another person? Furthermore, has it never happened that you assumed something to be true, lets say about nature, and one day you found nature to be acting in a differing way from what you believed? The reason these don't become apparent to you at first glance is simply because they don't bother us AS much. We don't have such a problem having nature contradict something we believed because we feel that nature is our basis, and if it says otherwise than it must be so. There is no arguing with nature. Moreover, we don't take issue with ourselves when we have a contradictory thought, we usually label the thought and say something like "that was a stupid idea, I wonder where I got it from". But we don't take it personally and get angry at ourselves for thinking that thought, not usually atleast. But when it comes to people, there are feelings at stake and we know that people are not always honest. We also know that some people would do us harm instead of good. Which is strange, because usually the people who present the least amount of threat and emanate trust throughout them, are not respected by society in general - they are seen as WEAK. But those who present themselves as threatening get all the respect and are seen as STRONG.
Now this relates to your post in some ways, because we, holding our truth, will automatically rejoice in the shortcomings of others because it obviously strenghens our own beliefs, and takes the legs out of others, bringing us that much closer to realizing the truth.
That doesn't follow, just because we wish to be right, doesn't mean that it follows that we rejoice in the shortcomings of others, nor does it mean it strengthens our beliefs. It just means we don't care about one another which is one of the greatest problems on this planet. See, if I care about you as a human being and I believe I am right and that you are wrong, it makes no sense for me to rejoice in your shortcomings. Instead it makes sense for me to speak with you and tell you my logic for my beliefs so that I can make you come to the same understanding and conclusion which WOULD strengthen my beliefs because you also believe it and may go onto spread MY truth to others. Hurting people, or proving them wrong doesn't help us come closer to realizing the truth, it promotes egoism which is usually later translated as weight for an argument, you will hear things like "I have convinced 30 people that I am right, therefore I am right". Which is a fallacious argument.
concluding my theory, i believe that the only way that one will come to realize the truth is by being the last living conscious in the world, that way there will be no more doubt.
There will still be your own doubt that will come with time and experience. It is exactly those who put others down to convince themselves they are right that are most susceptable to being wrong and feeling inadequate. Because their views aren't thought out whatsoever, it takes very little to show them to be wrong. Which usually leads them to going back to someone whom they see as weak whom they know they can go to and beat up on or berate. This was illustrated in many husband/wife abuse cases - where the husband would be shown to be wrong at work about something, he would come home and beat his wife and feel better about himself. This is what you are promoting theoutsider. The wise person realizes that there will ALWAYS be doubt, whethere there are a hundred billion people on the planet or one. Personally, I believe that there isn't a single thing about which we know everything, if there was, it would unlock the answers to the whole universe.
What's your take?
