Single Idea 9877

[filed under theme 9. Objects / A. Existence of Objects / 3. Objects in Thought ]

Full Idea

Earlier, Frege divided objects into subjective, actual objective, and non-actual objective; in the 'Grundgesetze' he emphasised logical objects; but in 'The Thought' the non-actual objects become exclusively thoughts and their constituent senses.

Gist of Idea

Late Frege saw his non-actual objective objects as exclusively thoughts and senses

A Reaction

Sounds to me like Frege was finally waking up and taking a dose of common sense. The Equator is the standard example of a non-actual objective object.
