Single Idea 17376

[filed under theme 7. Existence / E. Categories / 2. Categorisation ]

Full Idea

The most important desideratum of a classificatory scheme is that assigning an object to a particular classification tell us as much as possible about that object.

Gist of Idea

We should aim for a classification which tells us as much as possible about the object

Book Ref

A Reaction

We should probably say that the aim is a successful explanation, rather than a heap of information. If we are totally baffled by a particular type of object, it is presumably important to group the instances together, to focus the bafflement.


The 17 ideas from 'The Disorder of Things'

The possibility of prediction rests on determinism [Dupré]
Natural kinds are decided entirely by the intentions of our classification [Dupré]
Borders between species are much less clear in vegetables than among animals [Dupré]
Cooks, unlike scientists, distinguish garlic from onions [Dupré]
Wales may count as fish [Dupré]
Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré]
All descriptive language is classificatory [Dupré]
Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré]
It seems that species lack essential properties, so they can't be natural kinds [Dupré]
A species might have its essential genetic mechanism replaced by a new one [Dupré]
Kinds don't do anything (including evolve) because they are abstract [Dupré]
Even atoms of an element differ, in the energy levels of their electrons [Dupré]
Ecologists favour classifying by niche, even though that can clash with genealogy [Dupré]
The theory of evolution is mainly about species [Dupré]
Species are the lowest-level classification in biology [Dupré]
Natural kinds don't need essentialism to be explanatory [Dupré]
We should aim for a classification which tells us as much as possible about the object [Dupré]
