on certainty 203



203. [Everything* that we regard as evidence indicates that the earth already existed long before my birth. The Contrary hypothesis has nothing to confirm it at all.

If everything speaks for an hypothesis and nothing against it, is it objectively certain? One can call it that. But does it necessarily agree with the world of facts? At the very least it shows us what “agreement” means. We find it difficult to imagine it to be false, but also difficult to make use of it.]

* Passage crossed out in MS.

What does this agreement consist in, if not in the fact that what is evidence in these language games speaks for our proposition? (Tractatus Logico- Philosophicus)

                                                                                                                                      

you can’t know if everything speaks for a proposition and nothing against it –

all you can know is what has been said for it – or against it

if you find it difficult to imagine it to be false –

your problem is imagination

Wittgenstein asks –

what does this agreement consist in?

his answer is –

‘that what is evidence in these language games speaks for our proposition’

if it speaks for the proposition –

then it is a reassertion of the proposition –

and its only value will be –

rhetorical
