Single Idea 9142

[filed under theme 18. Thought / E. Abstraction / 7. Abstracta by Equivalence ]

Full Idea

Fine considers abstraction principles as instances of reconceptualization (rather than implicit definition, or using the Context Principle). This centres not on reference, but on new senses emerging from analysis of a given sense.

A Reaction

Fine develops an argument against this view, because (roughly) the procedure does not end in a unique result. Intuitively, the idea that abstraction is 'reconceptualization' sounds quite promising to me.

Implicit definitions must be satisfiable, creative definitions introduce things, contextual definitions build on things [Fine,K, by Cook/Ebert]
Fine's 'procedural postulationism' uses creative definitions, but avoids abstract ontology [Fine,K, by Cook/Ebert]
We can abstract from concepts (e.g. to number) and from objects (e.g. to direction) [Fine,K]
Points in Euclidean space are abstract objects, but not introduced by abstraction [Fine,K]
Abstractionism can be regarded as an alternative to set theory [Fine,K]
An object is the abstract of a concept with respect to a relation on concepts [Fine,K]
Many different kinds of mathematical objects can be regarded as forms of abstraction [Fine,K]
'Creative definitions' do not presuppose the existence of the objects defined [Fine,K]
Postulationism says avoid abstract objects by giving procedures that produce truth [Fine,K]
Abstracts cannot be identified with sets [Fine,K]
