“So if I say ‘he has toothache’ I am supposing that he has what I have if I have toothache.” Suppose I said: “If I say ‘I suppose’ he has toothache I am supposing that he has what I have if I have toothache”, – this would be like saying “If I say ‘this cushion is red’ I mean that it has the same colour which the sofa has if it is red”. But this wasn't what
was meant
I intended to say
with the first sentence. I wished to say that talking about his toothache at all was based upon a supposition, a supposition which ˇby its very nature essence could not be veryfied.
