A question I constantly struggle with is what gives someone's life value, and how I can find it for myself.
Does a person's life have value if the person simply exists selfishly, looking out for their own needs and desire? I'd say no, since that life adds no value to the world and doesn't increase happiness nor decrease suffering for others.
But devoting one's life to helping others doesn't fully solve it for me. It's nearly impossible to tell when the value one gives the world balances with what one takes to stay alive. Would one need to save one life to justify our own? Would one need to save one high-value life or several lower-value lives? Or give small bits of value and inspiration to lots of different people?
If one brings new life into this world with kids, does it only count if that life also brings value to the world? If someone produces a life that only takes and never gives, does that make one even less worthy of life?
Even doing all that, does helping others simply to help oneself count? They're using others as excuses or rationalizations to keep living. It's just become another selfish activity, using others as a means to an end.
It's a question with no answer yet keeps asking for one. I'm again left asking myself, how can we define the value of a life?
