Is the self all that can be known to exist?

[Excited Penguin]

Nor can I.  I can certainly assess specific contradictions and suggest that they may be subtle this or thats, but without complete knowledge I can;t possibly make the claim that no contradictions exist or that my answer to any given contradiction - or indeed my set of answers to sets of contradictions, is an answer to -every- contradiction that may exist.  

The self might be just such a thing.  I have no way of arguing the self in except by self referential statements regarding the self.  May as well say the self exists because the self exists.  OTOH< I don;t think that it does, which presents a potential paradox that's just as difficult to account for.

Why do you think the self doesn't exist ? 

It's an equivocation because it's equivocal.

The LOI and the LNC are both expressions of the same law. The first in positive form, the second in negative form. That something has to be something and that something cannot be not something are both expressing the same thing.

What do you mean by equivocal ? 

They are not the same law. They are two separate laws. NC and EM may follow from ID in some sense but they are all separate.
