Yoko Ono loves me. Or at least she said that she does in the e-mail interview we conducted as she crisscrossed the globe.

Peace and love have so long been central to Ono's public persona that it is tempting to view it cynically. What is the angle? How could anyone otherwise keep up this barrage of positivity, this wholehearted agape, even to strangers, except perhaps in the employ of a greeting-card company?

But one of the striking points about Ono's work is its utter lack of irony. In an age in which so much art is a meditation on the inability of art to communicate, Ono deeply believes in the exact opposite: in art's ability to connect and convey meaning. She has used every means, including the access to the media that marriage to John Lennon gave her, to promote her message of peace.
