All attempts to comprehend the writings of philosophers as poetry have missed their truth content. Philosophical form requires the interpretation of the real as a binding nexus of concepts. Neither the manifestation of the thinker’s subjectivity nor the pure coherence of the work determines its character as philosophy. This is, rather, determined in the first place by the degree to which the real has entered into concepts, manifests itself in these concepts, and comprehensibly justifies them. The interpretation of philosophy as poetry is opposed to this. By tearing philosophy away from the standard of the real, it deprives it of the possibility of adequate criticism. Only in communication with critical thought may philosophy be tested historically.
