Why, hang it all

What is the motivation? Why do it at all? Funny question, and I find my answer to it even funnier. My answer - because it never is going to be good. Of course, some things are better than others. Some other things are arguably good enough or meet whatever standards we determined for a particular purpose, but overall - nothing is ever going to be good in the final way, good in itself.
There is nothing pretty about justice. Justice is nothing more than the struggle to make everything better, which it can always be. In a way, there is nothing non-ideal about justice, it is always about something that we don't yet have.
Just as I don't think we will be able to explain it all, to have a final scheme of the natural laws - I don't think we can ever form the just society or live the good life, in the final and 'nothing better' way. While some bridegrooms would be depressed by this sort of thing, I find it encouraging. To me, that just means that they will always be more to be done. So why do it at all? Because there's more to be done.
