Single Idea 19468

[filed under theme 3. Truth / H. Deflationary Truth / 1. Redundant Truth ]

Full Idea

The sentence 'I smell the scent of violets' has just the same content as 'It is true that I smell the scent of violets'. So it seems that nothing is added to the thought by my ascribing to it the property of truth.

Gist of Idea

The property of truth in 'It is true that I smell violets' adds nothing to 'I smell violets'

A Reaction

This idea predates Ramsey's similar proposal, for which, oddly, Ramsey always seems to get the credit. To a logician they may have identical content, but pragmatically they are likely to differ in context. 'True' certainly doesn't add to the thought.


The 13 ideas from 'The Thought: a Logical Enquiry'

There exists a realm, beyond objects and ideas, of non-spatio-temporal thoughts [Frege, by Weiner]
Thoughts have their own realm of reality - 'sense' (as opposed to the realm of 'reference') [Frege, by Dummett]
A thought is distinguished from other things by a capacity to be true or false [Frege, by Dummett]
Thoughts about myself are understood one way to me, and another when communicated [Frege]
Late Frege saw his non-actual objective objects as exclusively thoughts and senses [Frege, by Dummett]
The word 'true' seems to be unique and indefinable [Frege]
There cannot be complete correspondence, because ideas and reality are quite different [Frege]
A 'thought' is something for which the question of truth can arise; thoughts are senses of sentences [Frege]
The property of truth in 'It is true that I smell violets' adds nothing to 'I smell violets' [Frege]
We grasp thoughts (thinking), decide they are true (judgement), and manifest the judgement (assertion) [Frege]
Thoughts in the 'third realm' cannot be sensed, and do not need an owner to exist [Frege]
A fact is a thought that is true [Frege]
A sentence is only a thought if it is complete, and has a time-specification [Frege]
