Single Idea 18615
[filed under theme 14. Science / B. Scientific Theories / 1. Scientific Theory

Full Idea
Horizontal arguments for eliminativism of theoretical terms say that some terms should be eliminated if they do not pick out a natural kind.

A Reaction
This is the one Machery likes, but I would say that it is less obvious than the 'vertical' version, since picking out a natural kind may not be the only job of a theoretical term. (p.238: Machery agrees!)

[Machery]
|
18564

18565
|
There may be ad hoc categories, such as the things to pack in your suitcase for a trip

Concepts should contain working memory, not long-term, because they control behaviour
[Machery]
|
18567
|
In the philosophy of psychology, concepts are usually introduced as constituents of thoughts
[Machery]
|
18569
|
In philosophy theories of concepts explain how our propositional attitudes have content
[Machery]
|
18570

|
18573
|

Concepts for categorisation and for induction may be quite different
[Machery]
|
18575
|
The concepts for a class typically include prototypes, and exemplars, and theories
[Machery]
|
18584
|
One hybrid theory combines a core definition with a prototype for identification
[Machery]
|
18585
|
Heterogeneous concepts might have conflicting judgements, where hybrid theories will not

18591
|
Classical theory can't explain facts like typical examples being categorised quicker
[Machery]
|
18590

|
18596
|
Prototype theorists don't tell us how we select the appropriate prototype
[Machery]
|
18597
|
Concepts as exemplars are based on the knowledge of properties of each particular
[Machery]
|
18598
|
Exemplar theories need to explain how the relevant properties are selected from a multitude of them
[Machery]
|
18599
|
In practice, known examples take priority over the rest of the set of exemplars
[Machery]
|
18600

[Machery]
|
18601
|
Theory Theory says concepts are explanatory knowledge, and concepts form domains
[Machery]
|
18602
|
A thing is classified if its features are likely to be generated by that category's causal laws
[Machery]
|
18603
|

|
18604
|
Are quick and slow categorisation the same process, or quite different?
[Machery]
|
18605

If categorisation is not by similarity, it seems to rely on what properties things might have
[Machery]
|
18609
|

[Machery]
|
18610
