. . . what I’m doing is equating my paintings with my poetry. In other words they are concrete. The LOVE is a concrete poem as far as I’m concerned. Just a one word poem. Repeated so endlessly by myself, and it’s a little bit like, shall we say, like Gertrude Stein. Just don’t stop using a word, you see . . . Remember there’s another aspect about love and of course this really comes through in [the poem] "Wherefore the Punctuation of the Heart." Love is a noun and a verb and so one must decide what my love is. It’s a command, love, and it’s a subject, love. It is an exercise, and grammar is one of my favorite subjects.
