Quote of Huelsenbeck, in 'Dada Lives', Transition no. 25 (Autumn 1936), as cited in The Dada Painters and Poets: An Anthology, ed. Robert Motherwell (1951)
Die Möglichkeit aller Philosophie ... dass sich die Intelligenz durch Selbstberührung eine Selbstgesezmäßige Bewegung - d.i. eine eigne Form der Tätigkeit gibt.
Schriften, p. 63, as translated in Walter Benjamin: Selected Writings: Volume 1, 1913-1926 (1996), p. 133
Earliest instance of this quote found on google books is the 1989 book Forest primeval: the natural history of an ancient forest by Chris Maser, but there it appears to be Maser's own thought (see p. 230 http://books.google.com/books?id=8EAHQM54E5gC&q=%a+mirror% followed by a different supposed Gandhi quote http://books.google.com/books?id=8EAHQM54E5gC&q=gandhi).
