Who cannot even draw
Her garments neat as they should be,
Her ankles roundabout?
And the tragedies of love's "limited". Defining for Pan-dora a "container/box"... complete with "defining limit" for the "all-good/gold" of "love"... for as Isaiah Berlin stated, there was an "unavoidability of conflicting ends" or, alternatively, "incommensurability" of values. He once called this "the only truth which I have ever found out for myself... Some of the Great Goods cannot live together.... We are doomed to choose, and every choice may entail an irreparable loss." In short, it's what Michael Ignatieff summarized as "the tragic nature of choice".
So what should we choose to form the limits of our love so that we avoid Pandora's mistake of unleashing all the evils in the world in the vain hope that nothing bad will happen as a result? You can't love EVERYTHING (all at the same time), can you? ;)
