Of many far wiser than we-- (line 29)
This opens up a bunch of questions about whether love and wisdom have anything to do with each other. Do you need to be wise and experienced in order to love completely? Can you make decisions for yourself about love when you are a kid? A lot of people would say no, or suggest that you should listen to people who are older than you, but our speaker doesn't seem to feel that way at all. He knows that other people must have more wisdom, but he doesn't think that gives them any right to judge his relationship, or to tell him what to do. He rejects the standard ways of deciding who should be in control (more knowledge, more years), and puts love at the top of the list.
