What does it mean to behave wisely?

When we really grasp and believe that we have to account for the way in which we have occupied ourselves during our earth life, it will make us behave more wisely.

A man can hardly sweat his work and enjoy wealth won for him at starvation wages when he knows for an absolute fact that he will someday feel for himself what they are suffering now. A man could not deliberately wrong an unprotected woman, knowing that someday he will suffer bitter biting remorse for his cruelty and not be able to make up for the wrong he had done in the way he would wish.

So you can multiply all sorts of different cases and apply the same test nationally. It would ultimately lead to the abolition of wars on the earth.
