Typewriter, Electronic Data Processor, Mind

An old-fashioned typewriter is a personalized Gutenberg invention--a key is tapped, and ink-covered type strikes a surface, leaving an impression of the type-character on the page.  In contrast, in an Electronic Data Processor, a key is tapped, initiating a sequence of logical operations involving binary code, eventually producing the appearance of a certain configuration of pixels on a screen.  Thus, the typewriter illustrates Locke's concept of Mind, e. g. a blank page as his Tabula Rasa, while the Electronic Data Processor illustrates Kant's, e. g. involving formal operations.  The contrast thus further suggests that rather than being rivals of equal value, one concept renders the other as obsolete, as is the case with Geocentrism and Heliocentrism.
