Notes from the book:
The task of philosophy is to resolve or dissolve philosophical problems by clarification of what makes sense... There can be no discoveries in philosophy, for everything that is relevant to a philosophical problem lies open to view in our rule-governed use of words... Philosophical problems are symptoms of conceptual entanglement in the web of language... To have a pain is no more to own anything, logically or otherwise, than is to have a bus to catch...
We construe the mind as an inner world to which only its 'owner' has access... But private ownership of experience is an illusion. Epistemic privacy is also illusory... In repudiating the idea of privileged, direct access to our own mental states, Wittgenstein was not affirming the idea that we have unprivileged, indirect access. In denying that we always know what mental states we are in, he was not claiming that we are sometimes ignorant that we are, for example, in pain... it and its negation alike are nonsense or, at least, do not mean what philosophical reflection takes them to mean... We mistakenly construe a grammatical connection or exclusion of words for an empirical or metaphysical connection or exclusion determining the essential nature of the mind...
an ascription of knowledge is supposed to be an empirical proposition which is informative in so far as it excludes an alternative... 'I know I am in pain' can be a claim to know something only if 'I do not know whether I am in pain' is intelligible... Where we speak of knowing that p, we can also speak of guessing, surmising and conjecturing that p. But it makes no sense to guess that one is in pain. In short, our conception of epistemic privacy of experience confuses the grammatical exclusion of ignorance with the presence of knowledge...
In place of the descriptivist, cognitivist, conception, Wittgenstein proposes a completely different picture - an expressivist, naturalist one... A child who wants his teddy reaches for it and cries out in frustration - we teach him the use of 'I want'. In reaching for his teddy, he does not first introspectively identify his inner state as volitional, and he no more does so when he says, 'I want teddy'... primitive forms of natural behaviour are antecedent to our learnt language-games... Spontaneous expressions of emotion, 'I like', 'I love', 'I hate,' are manifestations of affective attitudes. And like the natural forms of behaviour which these learnt utterances replace, such verbal forms of behaviour are logical criteria for corresponding third-person ascriptions of sensation, desire and emotion...
'I think' and 'I believe' are not learnt or used to describe an inner state which we observe within ourselves and then describe for the benefit of others. Rather, they are used to qualify a claim about how things are - to signify that we are not in a position to guarantee the sequel... The pegs upon which different psychological terms hang are various, but the differences do not reinstate the classical picture of the inner...
The complement of the misconception of privileged access is that we can know how things are with others only indirectly, that the 'inner' is hidden behind the 'outer' (ie, mere behavioural externalities - bodily movements and the sound of speech). This, too, Wittgenstein argued, is a misconception - but not because the inner is, as the behaviourists argued, a fiction... Joy, distress or amusement are not hidden behind the face that manifests them, but visible on it. What we so misleadingly call 'the inner' infuses the outer...
The thought that another person can only surmise that I am in pain (whereas I know I am) is wrong. "If we are using the word 'know' as it is normally used (and how else are we to use it?), then other people very often know when I am in pain."...
"The human body is the best picture of the human soul." (PI, p. 178)
Our psychological concepts are logically connected with the behaviour that manifests the inner. For it is the behaviour of a human being that constitutes the logical criteria for saying of him that he is perceiving or feeling something, thinking or recollecting, joyful or sad...
if it is nonsense to say 'my brain has a toothache', it is nonsense on stilts to claim that the brain poses questions and answers them, constructs hypotheses or understands arguments... Brains do not have opinions, argue, hypothesize or conjecture. It is we who do so. To be sure, we could not do so if our brain were destroyed; but then we could not have toothache or walk without a brain either - yet it is not the brain that has toothache and walks to the dentist.
