Is there such thing as a galactic taxonomy/uber taxonomy?
There are hundreds of thousands, perhaps hundreds of millions, of taxonomies in use in the world. Many of them are online. Every website navigation scheme has an underlying taxonomy. The great attempts to produce a universal classification system for knowledge, from Aristotle’s original categories and Francis Bacon’s creation of the modern natural sciences to the great Dewey Decimal and Library of Congress classification schemes, all have a taxonomy. They are all attempts at a galactic taxonomy.
