Blumenberg explores the use of metaphors in philosophy through a number of base-metaphors, including truth as a force, knowledge as light and so on. By using a number of key themes he is able to show the ways that philosophers over time have relied on the connotative power to emphasise their ideas, including a ‘push’ of their theories of ‘enlightenment.’
Most interesting is that Blumenberg traces many “founding” or “background” metaphors back to similar ‘branches’ and ‘roots’ some twenty years before Lakoff and Johnson coined the idea of “conceptual” metaphors. Blumenberg demonstrates through examples from philosophical treatises that truth is a force that presses upon us, moves us, propels us, pushes, pulls, sets itself as a seal upon our soul, the Americans Lakoff and Johnson would later use colloquial student-chit-chat to come to a similar conclusion, showing that when someone says ‘our relationship is going nowhere’ or ‘we’re on the skids’ that love is a journey.
Overall, an interesting read that highlight both the usefulness and trickiness of metaphors in language, thought, philosophy and literature. I particularly liked his notion that metaphorology is essentially an experiment, with the emphasis on the experience. In testing out the boundaries, stretching it into infinity, or collapsing it in upon itself, what at first seems logical and viable eventually falls apart and the metaphor ceases to be of assistance, and in fact ceases to be a metaphor. It is the experience of the transcendence of logic that makes metaphor analysis both rewarding and impossible. Metaphorology will therefore, always be a journey not a destination.
Even if you don’t read the whole book, don’t skip the translator’s notes at the end, as they explain much of Blumenberg’s approach.
