Just saw a statement saying that "happiness is synthetic"... Am writing a rebuttal here: Happiness is not synthetic. My working def. is that the sense of being and actuality of happiness is "what is keeping in line with what is positive to our nature". A similar idea/concept with "meaning", "purpose" in our lives. To delimit, categorize more fully; feeling happy from drugs, religious beliefs in para (note, not super) natural beings, events... are NOT sensations of happiness; as they are not based in reality. Though someone may "feel happy" temporarily, this "sort" of elation is short-lived and ultimately self-defeating... like pushing the hold button; a trifling of one's time, general resources.
It doesn't matter if happiness is synthetic or not, it's happiness. I synthesis my happiness, because if I really think deeply about the state of the world it would be enough to make me, at the very least, morose. Being sad, depressed, heartbroken doesn't change anything, so why not be happy and try to change the things I can change. Being happy energizes me. Being sullen, sad, down beaten, depressed depletes me. We can have a choice. Even if we synthesis it.(Having said that there is a place for all the other feelings that humans feel.)
Why are we happy?
