§159

We could imagine someone learning a Russian sentence by heart in order to convince a friend that they can read Cyrillic script (they can't). They then look at a sentence written in Cyrillic script and say the words they've learnt by heart. In this case their behaviour is just like someone who is reading but they are not reading which suggests that overt behaviour is not the criterion by which we determine whether someone is reading. It then seems that it must be something going on in their head that only they know about - a set of feelings or something like that.
