on certainty 349



349.  “I know that that’s a tree” – this may mean all sorts of things: I look at a plant that I take for a young beech and that someone else thinks is a black-currant. He says “that is a shrub”; I say it is a tree – We see something in the mist which one of us takes for a man, and the other says “I know that that’s a tree”. Someone wants to test my eyes etc. etc. –etc. etc. Each time ‘that’ which I declare to be a tree is of a different kind.

But what when we express ourselves more precisely? For example: “I know that that thing there is a tree, I can see it quite clearly.” – Let us even suppose that I made this remark in the context of a conversation (so that it was relevant when I made it); and I add “I mean these words as I did five minutes ago”. If I added, for example, that I had been thinking of my bad eyes again and it was a kind of sigh, then there would be nothing puzzling about my remark.

For how a sentence is meant can be expressed by an expansion of it and may therefore be made part of it.



‘Each time that which I declare to be a tree is of a different kind.’

what we have here is different descriptions applied to ‘that’

‘that’ – as such – without description –  is unknown
                                                                                                                                 
when we apply a description to ‘that’ –

what we do is propose a characterization –

the point of which is to enable us to act in relation to ‘that’ –

‘that’– does not determine its description –

and therefore the value of any description applied to ‘that’ –

will be a matter of its functionality –

in the circumstances to which it is applied

any so called ‘determination’ we make –

will be open to question – open to doubt –

and therefore will be uncertain

‘Let us even suppose that I made this remark in the context of a conversation (so that it was relevant when I made it); and I add “I mean these words as I did five minutes ago”.’

‘I meant these words as I did five minutes ago’ –

is really an attempt to guarantee the statement –

to give it an authority –

this underwriting is no more than – just another assertion –

the only authority is has – is its authorship

‘For how a sentence is meant can be expressed by an expansion of it and may therefore be made part of it.’

yes – you can expand a sentence –

and as interesting and as informative as that might be –

all you in fact do from a logical point of view –

is increase the domain of its uncertainty
