It is a man writing, not of the love of happy youth, but of love tossed on the stormy seas of manhood and womanhood, and modified from its singular personal intensity by the deeper thought, feeling and surprising chances of our mortal life.

Love does not stand alone, as in the true love lyric, but with many other grave matters.

As such it is a more interesting subject for Browning.
For Love then becomes full of strange turns, unexpected thoughts, impulses unknown before creating varied circumstances, and created by them; and these his intellectual spirituality delighted to cope with, and to follow, labyrinth after labyrinth.

I shall give examples of these separate studies, which have always an idea beyond the love out of which the poem arises.

In some of them the love is finally absorbed in the idea.
