This is something that I've wondered about for a while. Emotions provide the fuel for us - our passions, motivation, our inspirations. Fear causes us to be cautious. Anger spurs us to act and take a stand. Joy is replenishing. All emotions - negative or positive - pretty much have a positive in my mind.
But grief - and the associated depression - I see no redeeming value in this whatsoever. It seems like all downside. If grief were to be obliterated from the human experience, would things be better or worse? Is there any positive value in it whatsoever?
Anyone have any thoughts on this?
