Single Idea 8783

[filed under theme 6. Mathematics / C. Sources of Mathematics / 6. Logicism / c. Neo-logicism ]

Full Idea

Two modern approaches to logicism are the quantificational approach of David Bostock, and the abstraction-free approach of Neil Tennant.

Gist of Idea

Logicism might also be revived with a quantificational approach, or an abstraction-free approach

Source

B Hale / C Wright (Logicism in the 21st Century [2007], 1 n2)

Book Ref

'Oxf Handbk of Philosophy of Maths and Logic', ed/tr. Shapiro,Stewart [OUP 2007], p.167


A Reaction

Hale and Wright mention these as alternatives to their own view. I merely catalogue them for further examination. My immediate reaction is that Bostock sounds hopeless and Tennant sounds interesting.


The 5 ideas from 'Logicism in the 21st Century'

Neo-logicism founds arithmetic on Hume's Principle along with second-order logic [Hale/Wright]
One first-order abstraction principle is Frege's definition of 'direction' in terms of parallel lines [Hale/Wright]
Logicism might also be revived with a quantificational approach, or an abstraction-free approach [Hale/Wright]
The Julius Caesar problem asks for a criterion for the concept of a 'number' [Hale/Wright]
Logicism is only noteworthy if logic has a privileged position in our ontology and epistemology [Hale/Wright]
