§93-§97
I'm sure it's been mentioned (I know
@Banno has), but the next few sections cannot be understood outside of the context of a self-critqiue of the
Tractatus. It's this which helps understand the full import of §93 and §94, which otherwise come across - indeed, came across to me on first reading - as a rather thin effort to do nothing more than shift the rhetoric and poetics associated with propositions from 'remarkable' to 'ordinary'.
Yet while this effort to shift the language takes up most of the written real estate, the key term which explains what
motivates Witty to argue for this shift is that of is that of 'uniqueness' (also found in §95, §96 and §97): the proposition as 'unique', as doing something that nothing else in the world does. Specifically - as that which allows language to be correlative of the world (§96: "Thought, language, now appear to us as the unique correlate, picture, of the world.").
It's precisely in the
Tractatus that the proposition has exactly this 'unique' role attributed to it by Witty, in which the proposition 'pictures' reality by sharing the same 'logical form': this being the proposition's 'unique' characteristic which makes it 'remarkable' (hence the summary of
Tractatus, not yet named in §96: "These concepts: proposition, language, thought, world, stand in line one behind the other, each equivalent to each.")
Compare,
Tractatus:
2.026: There must be objects, if the world is to have unalterable form.
2.0271: Objects are what is unalterable and subsistent; their configuration is what is unchanging and unstable.
2.15: The fact that the elements of a picture are related to one another in a determinate way represents that things are related to one another in the same way.
2.1514: the pictorial relationship consists of the correlations of the picture's elements with things.
2.1515: These correlations are, as it were, the feelers with which the picture touches reality.
As such the nincompoop who, in §93 and §94, remarks upon the 'remarkableness' of propositions is of course Witty himself. Of course this becomes absolutely clear in §97 where the
Tractatus is mentioned by name, with the language even mirroring, and hence subverting, a passage that Witty himself cites
5.5563).
One of the really interesting things that happens in these
PI sections is then to realize just how explosive the 'relativization' of the simple and the complex undertaken in the sections before (§48-§7xx) are to the
Tractatus, which instead treats their relation as 'absolute', or, as Witty says in §97: "The order... which the world and thinking must have in common ... must be
utterly simple. It is prior to all experience". Lots more to say about all these, but will stop for space's sake. Will only remark that the distinction between 'concepts' and 'super-concepts' at the end of §97 is lovely, and
@Bannos
reading of §95 is exactly what'd I'd mention, so I simply refer to that.
