on certainty 218

218. Can I believe for one moment that I have ever been in the stratosphere? No. So I do know the contrary like Moore? 
                                                                                                                                  

you can put the proposition that you have never been in the stratosphere –

and that proposition – as with any proposition –

 is open to question –

open to doubt

to preface this assertion with ‘I know’ –

is to claim an authority for the assertion

the only authority you have is authorship –

it is irrelevant  and unnecessary –

to claim authorship of your assertion –

therefore –

logically speaking –

‘I know’ –

is irrelevant and unnecessary

it’s only value is –

rhetorical
