Single Idea 17316

[filed under theme 18. Thought / E. Abstraction / 3. Abstracta by Ignoring ]

Full Idea

In 'feature dependence', the ontologically dependent entity may be thought of as the result of a process of abstraction which takes the 'bearer' as its starting point and arrives at the abstracted entity by blocking out all the irrelevant features.

Gist of Idea

We can abstract to a dependent entity by blocking out features of its bearer

A Reaction

She seems unaware that this is traditional abstraction, found in Aristotle, and a commonplace of thought until Frege got his evil hands on abstraction and stole it for other purposes. I'm a fan.


The 8 ideas from 'Varieties of Ontological Dependence'

For Fine, essences are propositions true because of identity, so they are just real definitions [Koslicki]
Real definitions don't just single out a thing; they must also explain its essence [Koslicki]
It is more explanatory if you show how a number is constructed from basic entities and relations [Koslicki]
Modern views want essences just to individuate things across worlds and times [Koslicki]
The relata of grounding are propositions or facts, but for dependence it is objects and their features [Koslicki]
We need a less propositional view of essence, and so must distinguish it clearly from real definitions [Koslicki]
A good explanation captures the real-world dependence among the phenomena [Koslicki]
We can abstract to a dependent entity by blocking out features of its bearer [Koslicki]
