"John Clarke is among those stand-out poets who are guides of what to do in writing that thinks. So - we may come through. . . . Here we are just plain after the modern (to use Olson's clear recognition and step around the pile up of positivisms) and at work." Robin Blaser "John Clarke uses language like a can opener to breach the orders of thought (the essential tautologies of self-Being) that we might get at the meat of the Potentiality locked within." Diane di Prima "With a depth of humanity and intelligence hardly visible anymore in our culture, Jack Clarke's work makes possible trajectories of thought that have largely been denigrated, suppressed or foreclosed in the little "public space" we cling to for dear life." Ammiel Alcalay "Next to Olson's Projective thesis, Jack Clarke's From Feathers to Iron: a Concourse of World Poetics, is the best poetics thus far written for the next 100 years to study, for all schools." Vincent Ferrini "Jack Clarke took it as far beyond Charles Olson as Olson took it beyond Ezra Pound." Albert Cook
