in reply to How do I know what I 'know' is right?

Every abstraction that is not a tautology contains some lie, and is therefore only applicable to some subset of all cases. The better abstractions cover more cases.

So, everything I know is a lie. I should always be prepared to eject any knowledge I have in light of some abstraction that covers more of the territory. It's all models, but some models are better than others.

    Such as..."all premises, major or minor, involved in the construction of a syllogism are lies".

    Hmmm. Granted, deductive reasoning is only a subset of logic.

      And logic is only a subset of real life ;-)
