There was a time when it was assumed that God had created a perfectly ordered the universe. Within that universe, we assumed that each thing had its own place, clustered with other things like it, but also each being essentially different from the other things in the cluster. The clusters were themselves clustered, creating a Grand Tree of Everything, each branching determined by a perfectly unambiguous definition.
But, although God knew all of the the definitions, it was often hard for mere mortals to grasp exactly what it was that He had in mind. What were the most relevant principles guiding decisions about likeness and difference? For example, did it matter more where they lived, how they looked, or how they behaved?
Finally, we got past the notion that there must be a single right order. Now, for all of those who want to know their universe the task of creating order in the world is more like: Go forth and lump and split. “Lump” and “split,” are, surprisingly, technical terms currently in use among professional indexers. A “Lumper” takes things that seem disparate and combines them because they have something similar. A “Splitter” tends to take two things that are lumped together and separate them into smaller categories. Indexers tend to be one or the other, their technique driven by their personality.
So, go forth into your world and Lump and Split. Order is in the eye of the tagger.
