Single Idea 19210
[filed under theme 19. Language / D. Propositions / 2. Abstract Propositions / a. Propositions as sense
]
Full Idea
The standard view among philosophers nowadays seems to be that propositions do not and even cannot change in truth-value. But my own view is that some propositions can, and do, change in truth value.
Gist of Idea
The standard view of propositions says they never change their truth-value

A Reaction
He gives 'that A sits' as an example of one which can change, though 'that A sits at time t' cannot change. I take Merricks to be obviously right, and cannot get my head round the 'standard' view. What on earth do they think a proposition is?
