the thought of existentialist philosophers such as Heidegger , and Kierkegaard : "The subjective thinker’s form , the form of his communication, is his style . His form must be just as manifold as are the opposites that he holds together. The systematic eins, zwei, drei is an abstract form that also must inevitably run into trouble whenever it is to be applied to the concrete. To the same degree as the subjective thinker is concrete, to the same degree his form must also be concretely dialectical. But just as he himself is not a poet, not an ethicist, not a dialectician, so also his form is none of these directly. His form must first and last be related to existence, and in this regard he must have at his disposal the poetic, the ethical, the dialectical, the religious. Subordinate character, setting, etc., which belong to the well balanced character of the esthetic production, are in themselves breadth; the subjective thinker has only one setting—existence—and has nothing to do with localities and such things. The setting is not the fairyland of the imagination, where poetry produces consummation, nor is the setting laid in England, and historical accuracy is not a concern. The setting is inwardness in existing as a human being; the concretion is the relation of the existence-categories to one another. Historical accuracy and historical actuality are breadth."
