some Wittgenstein quotes

from Philosophical Investigations (Anscombe transl.):

I.
207. Let us imagine that the people in that country carried on the usual human activities and in the course of them employed, apparently, an articulate language. If we watch their behaviour we find it intelligible, it seems 'logical'. But when we try to learn their language we find it impossible to do so. For there is no regular connexion between what they say, the sounds they make, and their actions...

293. If I say of myself that it is only from my own case that I know what the word "pain" means--must I not say the same of other people too? And how can I generalize the [i]one[/i] case so irresponsibly? ...Suppose everyone had a box with something in it: we call it a "beetle". No one can look into anyone else's box. and everyone says he knows what a beetle is only by looking at [i]his[/i] beetle. --Here it would be quite possible for everyone to have something different in his box. One might even imagine such a thing constantly changing. --But suppose the word "beetle" had a use in these people's language?...

II.
xi. ...Could there be human beings lacking in the capacity to see something [i]as something[/i]--and what would that be like? What sort of consequences would it have? --Would this defect be comparable to colour-blindness or to not having absolute pitch? --We will call it "aspect-blindness"...The 'aspect-blind' will have an altogether different relationship to pictures from ours.

...We also say of some people that they are transparent to us. It is, however, important as regards this observation that one human being can be a complete enigma to another. We learn this when we come into a strange country with entirely strange traditions; and, what is more, even given a mastery of the country's language....

"I cannot understand what is going on in him" is above all a [i]picture[/i]. It is the convincing expression of a conviction. It does not give the reasons for the conviction. [i]They[/i] are not readily accessible.

If a lion could talk, we could not understand him.

Is there such a thing as 'expert judgment' about the genuineness of expressions of feeling? --Even here, there are those whose judgment is 'better' and those whose judgment is 'worse'. ...Can one learn this knowledge? Yes; some can. Not, however, by taking a course in it...
