Since our positive emotions allow us to experience the good qualities of life while our negative emotions allow us to experience the bad qualities of life, then our positive emotions are literally a force of goodness flowing through us while our negative emotions are literally a force of badness flowing through us. It's, in a way, no different than a positive or negative charge. Therefore, all famous artists and composers who have used their depression and misery as an inspiration for their art weren't living any sort of good life at all. They did not have the force of light (i.e. goodness) flowing through them. In a purely naturalistic universe, it would be the force of goodness. But in a spiritual universe, it would be the light of god. This means that the only true way to live one's life and be an artist is through one's positive emotions as they are the only things that can allow us to experience the good qualities of life. These famous and genius miserable artists have mistakenly thought that they were experiencing the good qualities of life through inspiring others and whatnot through their art when this couldn't be any further from the truth. Now, I wish to be a composer. This means that I must fully recover from any emotional trauma and misery in my life before I can finally embrace and celebrate the good qualities of my life and composing. Without the light in my life, then my life can only be darkness or just simply blank (neither light nor dark). It's no way to live or be an artist. Our positive emotions are the only things that can make our lives worth living in a good way. Let me actually break it down for you: It is an established fact that our emotions are everything to our lives. Without emotions, then nothing could matter to us. We could have thoughts of things mattering to us, but nothing would actually matter to us. From here, this is where my theory comes in. It is not our negative emotions that make our lives matter to us in good ways. It is only our positive emotions that do this while our negative emotions can only make our lives matter to us in bad or horrible ways. This theory, if true, could change the world and help find cures and create a utopia life for us all so that people and artists can live the lives they were truly meant to live. As for the types of experiments we can perform to discover evidence for my theory if there really is evidence for it, I do not know. I am not good when it comes to ideas for experiments.
