@MozartLink,
If anyone wants a brief summary of my philosophy, here it is:
My philosophy says that positive feelings are the only way we can see things as good, beautiful, amazing, and magnificent, and that a life without positive feelings is no way to live or be an artist. I'll explain. Feelings are how we experience things. For example, feeling hungry is how we experience hunger, feeling thirsty is how we experience thirst, feeling sleepy is how we experience sleepiness, feeling pain and pleasure is how we experience them, feeling love (a positive feeling) is how we experience love, feeling pride and happiness (positive feelings) is how we experience pride and happiness, and feeling that life's beautiful is how we experience life as beautiful (which is also a positive feeling).
Perception and experience are the same thing. For example, if you're seeing (perceiving) the color red, then you're experiencing red, and vice versa. So, if you feel amazed about something (such as a singing performance), you're experiencing the performance as amazing, which is the same thing as saying you're seeing (perceiving) the performance as amazing. That's why, if our positive feelings get taken away by brain damage, a mental illness, etc., we can no longer see goodness, beauty, magnificence, etc. in anything, and that's no way to live or be an artist. So, if a clinically depressed person witnessed a singing performance, he couldn't see anything amazing about the performance if his positive feelings were absent. Since positive feelings are also how we experience love, happiness, and pride, we can no longer love, be happy, or be proud without our positive feelings either.
