Fun, philosophical reflections from Alva Noe, who insists on love as a form of perception and hard work at that.  An excerpt:

Love, in a similar way, is an achieved openness. Love, I think, is a sustained openness to another person. It's hard to learn to read; in general, although we never notice this, it is very heard to learn to see. The purpose of education is to teach us how to see. It is very hard to be able to see another person. To see someone you must know him or her. Sometimes we just cannot see what is there before us!
