This question has bothered me for a long time but I decided not to share it with anyone because I find that someone else might actually live by it. Personally I subscribe to some form of utilitarianism as my moral Philosophy and its been quite obvious to me that moral behavior should be the default position anyone should take.
The only flaw which I've clearly seen in that the evidence that other people are actually real people capable of suffering is nowhere to be seen. I say this because when I dream I am convinced it is real world yet I know people in my dream did not really suffer like I thought they did. And just like many other philosophers claim the only thing you can be certain of is your own existence. Based on my own experience I also learned that certain actions bring certain results which I like (but others appear not to). In my life I however run across no evidence that the people around me are real or that they feel emotions like I do and are capable of suffering.
Just like in dreams Im not able to tell if its a dream Im not really capable of saying that this is not a dream. I know there are differences in dreams and realities just that in my dream state Im not capable of noticing them. This is also touched upon in this question.
My other problem is that I don't really see a reason for consciousness at all. I have reasoned with myself for a long time but when it comes down to it I dont see why certain basic functions all the sudden should give rise to an actual conciseness rather then fake consciousness. In other words why dont things behave like they feel when they dont actually feel. Just like a program thats design to act like an ant if you cut off this droid-ant leg it can go running around in the circle like a real ant but it feels no pain. (and do real ants feel pain? I surely dont think so) And why should humans? No consensus on this point is needed for me to drive my point home.
Bottom line is this things are either real or they are not real. There is no way for us to tell either way or the other. If this is true then people in the world are either real or not. Either could be true.
If we follow this logic then why not choose a moral code which says that whatever is best or us is the best choice. Of course other people could be real but they might as well not be real. Why choose a morality that benefits groups rather then a morality that benefits the individual self. If we choose the wrong morality we do end up causing a lot of harm. (If i waste my time on other humans to make them happy when they aren't real that is horrible, If I however sacrifice them for my own utility and they are real then its immoral as well)
And just like in dreams our actions still have an effect but our dreams are completely made up realities.
Where do I make the error in my logic.
-There are many times that I had a regret about not doing something in my dream because of my moral code which stopped me.
