Are emotions such as courage, bravery, fear, love, sadness, and happiness humanity greatest weakness or greatest strength? As I see it there are three sides to this debate.
Greatest Advantage: Fear would keep us from putting ourselves in deadly situations, courage will help us fight, happiness helps us stay focused.
Neutral: It is neither, our emotions can come in handy and also be a burden.
Greatest Weakness: Fear can keep us from saving our own lives (unlikely example: needing to jump from cliff to cliff to avoid wolves or something). Courage can make us do things when the odds are against us and survival chances are low. Love can be very distracting.
I for one side with the Neutral.
