Reduction

When reading the assigned chapters from Idhe's work, I found myself wondering why sovereignty of the perception of reality was reserved for our senses. The "human" part of Idhe's equation never alters, even as tools pass from present-at-hand to transparent. What about our senses makes them the best judge of reality? Our sense of sight can be faulty. Tiny variations in photoreceptive cells from eye to eye lead to subtle, yet different, realities for each person who looks through a telescope or microscope. Idhe considers the translation of audible sound into visual waves to be reducing its dimension - but perhaps it isn't so much "reducing" as "exacting" or "refining." No longer are a person's inner ear bones or nerves responsible for interpreting sound, it is displayed with precision in digital format. Anyway, that was what went through my head when we discussed tools and their place between humans and the world. Our own senses, which phenomenology seems to reguard as sovereign, are hermeneutic. Where does that lead us?
