Why do we feel emotions?
According James-Lange theory, emotions serve to explain and organize our own actions to us. It's a way that our "system" has, to inform us what we do right and what wrong. If something doesn't seem to agree with our desire, our emotions will let us know it by, hating, crying, feel depression, etc... But if something identifies our desire we feel love, happiness, joy and the rest of the nice emotions.
But how we should know which of these emotions are the good ones?
I mean why Love is a beautiful emotion and hate isn't?
Who will determine that? How do we know that the earth's position is upside and not the other way?
