This sequence of one hundred sonnets was composed between 1967 and 2013. The title, Notness, is an anagram of the word 'Sonnets'. The word 'Metaphysical' in the subtitle is a pointer to some of the tendencies and intentions in and surrounding the title. The only further key - or, rather, hint - that needs to be offered here is that the so-called 'core' of isness is notness, just as at that of notness is isnesss: a never-ending dance.
