FOM: indubitability (or "certainty")

[jk]

To Neil Tennant:

Thank you very much for the clarification of Wittgenstein's views. So the
essence of the argument is non-uniqueness? Also, in regard to this part of
your remark:

> Conversely,
>the Wittgensteinian worry will arise even for surveyable proofs, provided
>only that some of their steps are 'new', in the sense that the rules being
>applied have never been applied to those instances before.
>

if the arguments (or the worry) apply as well to surveyable proofs why does
Wittgenstein always use unsurveyable proofs as examples?
