Single Idea 13387

[filed under theme 9. Objects / A. Existence of Objects / 2. Abstract Objects / b. Need for abstracta ]

Full Idea

There is no denying the access of power that accrues to our conceptual scheme through the positing of abstract objects.

Gist of Idea

Our conceptual scheme becomes more powerful when we posit abstract objects

Source

Willard Quine (Speaking of Objects [1960], §5)

Book Ref

Quine,Willard: 'Ontological Relativity and Other Essays' [Columbia 1969], p.21


A Reaction

This seems right, both in its use of the word 'posit', and in its general pragmatic claim. So why? If they enable us to grapple with the world better, it must be because of their power of generalisation. They are nets thrown over chunks of reality.


The 7 ideas from 'Speaking of Objects'

"No entity without identity" - our ontology must contain items with settled identity conditions [Quine, by Melia]
Our conceptual scheme becomes more powerful when we posit abstract objects [Quine]
There is no proper identity concept for properties, and it is hard to distinguish one from two [Quine]
I prefer 'no object without identity' to Quine's 'no entity without identity' [Lowe on Quine]
We can only see an alien language in terms of our own thought structures (e.g. physical/abstract) [Quine]
You could know the complete behavioural conditions for a foreign language, and still not know their beliefs [Quine]
Translation of our remote past or language could be as problematic as alien languages [Quine]
