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

Source

John Dupré (The Disorder of Things [1993], Ch 1)

Book Ref

Dupré,John: 'The Disorder of Things' [Harvard 1995], p.18


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 John Dupré

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]
All descriptive language is classificatory [Dupré]
Wales may count as fish [Dupré]
Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré]
Cooks, unlike scientists, distinguish garlic from onions [Dupré]
Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré]
Kinds don't do anything (including evolve) because they are abstract [Dupré]
A species might have its essential genetic mechanism replaced by a new one [Dupré]
It seems that species lack essential properties, so they can't be natural kinds [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]
Species are the lowest-level classification in biology [Dupré]
The theory of evolution is mainly about species [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]
