Single Idea 5747

[filed under theme 7. Existence / D. Theories of Reality / 11. Ontological Commitment / b. Commitment of quantifiers ]

Full Idea

Quine's well-known slogan "no entity without identity" means that no object should be admitted into our ontology unless its identity conditions, the conditions that say which object it is, have been settled.

Clarification

Our 'ontology' is what we believe exists

Gist of Idea

"No entity without identity" - our ontology must contain items with settled identity conditions

Source

report of Willard Quine (Speaking of Objects [1960]) by Joseph Melia - Modality Ch.4

Book Ref

Melia,Joseph: 'Modality' [Acumen 2003], p.95


A Reaction

This invites science fiction scenarios, where we admit the existence of something before we have a clue what it is (whether it is physical, hallucination, divine..). Quine's slogan seems attractive but optimistic. How 'settled'?


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]
