 Characteristic of the philosophy of symbolic forms is a concern for the more “primitive” forms of world-presentation underlying the “higher” and more sophisticated cultural forms – a concern for the ordinary perceptual awareness of the world expressed primarily in natural language, and, above all, for the mythical view of the world lying at the most primitive level of all. For Cassirer, these more primitive manifestations of “symbolic meaning” now have an independent status and foundational role that is quite incompatible with both Marburg neo-Kantianism and Kant’s original philosophical conception. In particular, they lie at a deeper, autonomous level of spiritual life which then gives rise to the more sophisticated forms by a dialectical developmental process. From mythical thought, religion and art develop; from natural language, theoretical science develops. It is precisely here that Cassirer appeals to “romantic” philosophical tendencies lying outside the Kantian and neo-Kantian tradition, deploys an historical dialectic self-consciously derived from Hegel, and comes to terms with the contemporary Lebensphilosophie of Wilhelm Dilthey, Henri Bergson, Max Scheler, and Georg Simmel – as well as with the closely related philosophy of Martin Heidegger.
