First off, that example I gave of the rich person was just an example. I said nothing in regards to the idea that people can will themselves to feel positive emotions anytime they want to. That has nothing to do with my theory. My theory was simply that positive emotions allow us to experience the good qualities of life to make our lives matter to us in good ways. You say that emotions are not the crux of humanity, but I am just not so sure on this. I had a discussion with someone who, in fact, said they were absolutely necessary. He was a highly intelligent skeptic. As a matter of fact, many highly intelligent people think like him and they also claim to have much evidence on their side as well. So, maybe this whole issue is controversial rather than a definite conclusion that you are making it out to be or I am making it out to be. But here is his reply though: There is a big difference between personal definitions and qualities. Just because you define your own happiness does not mean that it is actually there. That does not somehow magically make a real quality of happiness appear for you. I think our positive emotions can only be those biochemical induced euphoric states. It's no different than if there was an empty glass and you defined a quality of water to be inside that glass. That would not make a quality of water appear inside that glass. The only way to have real water inside that glass would be if you poured water inside it just as how the only real way to have happiness (positive emotions) is through your euphoric states.
