Why ought one do that which is good? Why should you or I or anyone else value “sustaining society” more than our own comfort or advantage? — J
We need to take the long view of our evolution, going far back beyond civilization.
I’m going to return to my earlier point that notions of “good’ and “bad” only evolved through social interactions. The universe is neutral. To determine if something is good or bad requires human judgement, and what is being judged is one’s behavior towards another. Does it serve the interests of the group? This is what we are hard-wired for.
Consider the universal virtues of honesty, justice, loyalty or humanity – they can only come to light in relationships between people, or groups. Even creativity requires the artist and the receiver of the art.
There is no such thing as solitary goodness, or badness. Goodness is manifested in co-operation and strengthened relationships, and badness in harm to others.
Now, the question "Why should we?" might be answered by: Because we want to belong to the group. Because we want to live in peace. Because we want safety and security.
