Single Idea 18970

[filed under theme 27. Natural Reality / C. Space / 3. Points in Space ]

Full Idea

Unless we are prepared to believe that absolute position makes sense, the very idea of a point as an entity in its own right must be rejected as not merely mysterious but absurd.

Gist of Idea

The concept of a 'point' makes no sense without the idea of absolute position

Source

Willard Quine (Propositional Objects [1965], p.149)

Book Ref

A Reaction

The fact that without absolute position we can only think of 'points' as relative to a conceptual grid doesn't stop the grid from picking out actual locations in space, as shown by latitude and longitude.

A 'proposition' is said to be the timeless cognitive part of the meaning of a sentence [Quine]
The problem with propositions is their individuation. When do two sentences express one proposition? [Quine]
How do you distinguish three beliefs from four beliefs or two beliefs? [Quine]
The concept of a 'point' makes no sense without the idea of absolute position [Quine]
