Single Idea 23455
[filed under theme 18. Thought / A. Modes of Thought / 6. Judgement / a. Nature of Judgement
]
Full Idea
When I judge 'Socrates is human', the meaning is completed by the act of judging.
Gist of Idea
The meaning of 'Socrates is human' is completed by a judgement
Source
B Russell/AN Whitehead (Principia Mathematica [1913], p.44), quoted by Michael Morris - Guidebook to Wittgenstein's Tractatus
Book Ref
Morris,Michael: 'Guidebook to Wittgenstein's Tractatus' [Routledge 2008], p.84
A Reaction
Morris says this is Russell's multiple-relations theory of judgement. The theory accompanies the rejection of the concept of the unified proposition. When I hear 'Socrates had a mole on his shoulder' I get the meaning without judging.
