"We may say: only someone who already knows how to do something with it can significantly ask a name."

   "'Thought' sometimes means a particular mental process which may accompany the utterance of a sentence and sometimes the sentence itself in the system of language.
   'He said those words, but he didn't think any thoughts with them.' - 'Yes, I did think a thought while I said them'. 'What thought?' 'Just what I said.'
   On hearing the assertion 'This sentence makes sense' you cannot really ask 'what sense?' Just as on hearing the assertion 'this combination of words is a sentence' you cannot ask 'what sentence?'"
