Are you disputing Russell's point that "I" is a construct and "thinking" is
all you have without inference?

I don't think much of anything can be derived from just "I think". For
example, "I think" is consistent with "Pigs fly" and with "Pigs don't fly";
so you can't infer whether or not pigs fly.

But if you weren't sane you might still think you were. To hold a rational
discussion you'd need to assume or prove there's someone to talk to.

I "think" not.

Or just assumes it.

Did you mean "implies"??
