'For the person or persons that hold dominion, can no more combine with the keeping up of majesty the running with harlots drunk or naked about the streets, or the performances of a stage player, or the open violation or contempt of laws passed by themselves than they can combine existence with non-existence'.

- Benedict de Spinoza. Political Treatise. 1677.

on certainty 1


1. If you do know that here is one hand, we will grant you all the rest.

When one says that such and such a proposition can’t be proved, of course that does not mean that it can’t be derived from other propositions; any propositions can be derived from other ones. But they may be no more certain than it is itself. (On this a curious remark by H. Newman.)



‘If you do know that here is one hand, we will grant you all the rest.’

if you are certain of one proposition  -

any derived from it – will be certain?

the question is can you be certain of any proposition?

certainty is what?

a claim to an authority that is beyond question –

first up the only authority you have is authorship –

secondly any proposition – any proposal – you put forward –

is open to question – open to doubt

the claim of certainty is at best no more than a rhetorical claim –

the point of which is to persuade – yourself – or others –

of an authority (beyond authorship) – that you don’t have –

it ‘s a false claim – based the in deception or ignorance

and yes – derivation – is really just a language game –

it guarantees nothing
