Single Idea 17385

[filed under theme 26. Natural Theory / B. Natural Kinds / 1. Natural Kinds ]

Full Idea

A kind, being an abstract object, cannot do anything, including evolve.

Gist of Idea

Kinds don't do anything (including evolve) because they are abstract

Source

John Dupré (The Disorder of Things [1993], 2)

Book Ref

Dupré,John: 'The Disorder of Things' [Harvard 1995], p.40


A Reaction

Maybe. We might have an extensional view of the kind, so that 'gold' is the set of extant gold atoms. But possible gold atoms are also gold, and defunct ones too. Virtually every word in English is abtract if you think about it long enough.


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]
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]
