“But no matte what kind of an understanding is adopted, whether associated with positivism, which asserts that the truth can only be reached by trial and error, or rationalism, which asserts that everything can be explained and grasped by reason, whether the perspective of romanticism, which overemphasizes imagination and sensitivity, or an approach based on ardent naturalism, whether based on realism, which aims to describe everything as it is including its shortcomings, or a curiosity-raising approach such as surrealism, whether idealism, which asserts that there is nothing real but ideas, or cubism, which asserts that there is nothing real but instead of direct description, or some other such current or perspective, that is not true poetry.”
