Absolute metaphor


The term absolute metaphor describes the special case of a metaphor that has become independent of the facts it illustrates. It was coined by the German philosopher Hans Blumenberg in the context of his collaboration on the project of history of concepts.
Blumenberg adopted from Immanuel Kant the phrase describing the relation between the physical world and the Unknown, modifying it as the "transfer of reflection on an object of intuition to a completely different concept, to which perhaps no intuition can ever directly correspond." For example, "world is a theater" is an absolute metaphor as it compares an impossible-to-define concept to an apparently unrelated one.

Significance

Within rhetorical theory, an absolute metaphor is strictly a contradictio in adiecto. For Blumenberg, metaphors are "absolute" when "they prove resistant to the terminological claim, cannot be resolved into concepts." According to the traditional understanding of metaphors, this resolution must in principle possible, as metaphors merely serve to embellish a speech or, especially in science, to provide illustrative clarification.
In contrast, Blumenberg argues that an absolute metaphor can come to influence, if not dominate, the entire theory formation of the subject it illustrates. He demonstrated, for example, that the metaphor of "light" has been of paradigmatic importance for theories of "truth" since antiquity. This includes the metaphysical opposition of Being and Non-Being, as well as the methodologically reflective illustration of subjective truth.
Absolute metaphors tend to occupy the semantic field of concepts that lack immediate, sensory intuition. Following Kant, Blumenberg calls such concepts Ideas. These include "truth," "freedom," "state," "world," "life," or "history." They are concepts that "overwhelm" the normal process of judgment or are used in "drastic" situations that require "quick orientation." The exemplary case of an absolute metaphor is thus a tangible image for an object that fundamentally eludes any visualization. Unlike scientific terminology, which aims for clear definition, absolute metaphors structure the "lifeworld".

Metaphor and concept

Absolute metaphors are understood as intuitions for ''Ideas. As such, they are part of the "substructures of thought." Blumenberg describes them as the "ground" or "nutrient solution" from which "systematic crystallizations" — that is, concepts — emerge.
Blumenberg emphasizes the necessity of this "metaphorical external determination''." The metaphor functions as a "placeholder for the Idea," which refers to the "totality of possible experience" and can therefore never be fully "brought to the concept." There is a "vacancy of the concept, which only the imagination can fill."
This makes the use of such metaphors both essential and precarious. While the abstraction from these images leads to a mystification of the concept, an uncritical surrender to the associative flood of images leads to a naive, pre-rational way of thinking. Blumenberg saw a "double hyperbole" at play: "The concept ends in mysticism, the metaphor in myth."
