The basic claim of science is objectivity: it attempts, through the application of a well defined methodology, to make statements about the universe. At the very root of this claim, however, lies its weakness: the a priori assumption that objective knowledge constitutes a description of that which his known. Such an assumption begs the question 'What is it to know?' and 'How do we know?'.
—Humberto Maturana, Biology of Cognition, 1970.
