4 sources of learning are:
Copying others
Using logic and definitions
Experience
Considering all possibilities
Copying others is a quick way to learn, and easy.
And as for superior way to live a life, we get three choices:
- treat others worse than they treat you
- treat others equally as they treat you
- treat others better than they treat you
Number 1 is a terrible way to live a life, because its guaranteed to make many enemies.
Number 2 seems balanced.
Number 3 is actually most superior of the three choices, because it gives people incentive to treat you better as well.
Of course, no way to live a life is perfect. Some ways are just superior to others in most cases. And in social relationships, you want to have many friends and not many enemies, because enemies will seek to hurt you.
