Single Idea 9919
[filed under theme 18. Thought / E. Abstraction / 2. Abstracta by Selection
]
Full Idea
The original debate was over abstract ideas; thus it was mental (or linguistic) representations that were classified as abstract or otherwise, and not the entities represented.
Gist of Idea
The old debate classified representations as abstract, not entities

A Reaction
This seems to beg the question of whether there are any such entities. It is equally plausible to talk of the entities that are 'constructed', rather than 'represented'.
