Philosophical Grammar 80

80. In the schema “ This is how things stand” the “how things stand” is a handle for the truth-functions.

A general propositional form determines a proposition as part of a calculus.

yes – the truth function game – like any game runs on the premise – this is ‘how things stand’

however any concept in any game is open to question – open to doubt

the truth function calculus is a product of questioning and doubt –

however if you play the game – you play it as prescribed –

you play it on the premise ‘this is how things stand’ –

there is no room for questioning and doubt in the game as played

there is no general propositional form –

a proposition is a proposal – and a proposal can take any number of different forms

devising a calculus is devising a game

and yes – you can play games with propositions
