Single Idea 11102

[filed under theme 18. Thought / E. Abstraction / 1. Abstract Thought ]

Full Idea

Applying the operator '-ness' or 'class of' to abstract general terms, we get second-level abstract singular terms.

A Reaction

This is the derivation of abstract concepts by naming classes, rather than by deriving equivalence classes. Any theory which doesn't allow multi-level abstraction is self-evidently hopeless. Quine says Frege and Russell get numbers this way.


The 12 ideas from 'Identity, Ostension, and Hypostasis'

To unite a sequence of ostensions to make one object, a prior concept of identity is needed [Quine]
A river is a process, with stages; if we consider it as one thing, we are considering a process [Quine]
We don't say 'red' is abstract, unlike a river, just because it has discontinuous shape [Quine]
We should just identify any items which are indiscernible within a given discourse [Quine]
Discourse generally departmentalizes itself to some degree [Quine]
'Red' is a single concrete object in space-time; 'red' and 'drop' are parts of a red drop [Quine]
Red is the largest red thing in the universe [Quine]
General terms don't commit us ontologically, but singular terms with substitution do [Quine]
Understanding 'is square' is knowing when to apply it, not knowing some object [Quine]
We aren't stuck with our native conceptual scheme; we can gradually change it [Quine]
Concepts are language [Quine]
Apply '-ness' or 'class of' to abstract general terms, to get second-level abstract singular terms [Quine]
