I am nonplussed yet excited, as if on some important trail I cannot get hold of. X is not random reconstruction: then what does he do? Could it be logically or mathematically described? If he is saying something apparently insignificant, he can produce coherent, recognizably coherent, speech. Then he may become vehement and speak emphatically. “Then we went down the road. It was” (persuasive and confidential) “just a quite ordinary road. And I said to him, “This won't do” (quietly emphatic and faintly reminiscent of the “I said it very loud and clear” verses of Lewis Carroll). I just made it obvious to him that it just would not do”, the last three words spoken quietly but each one separately emphasized. Has it any meaning for me? And if it has, what is that meaning? And is the meaning it has of any importance except as an indication of my personality and how it reacts to a particular form of stimulus? Yes, obviously it has, because I have just spoken of a ‘particular form of stimulus’ and this at once suggests (a) it is a stimulus, and (b) it has a particular form.
