Yes. nice to see you on the everything list!
So maybe I asked for the wrong thing from Edgar.
I think that you ask, what we all ask. To be intelligible. But Edgar,
like some other seem to have "certainties", which is a defect of bad
scientists/philosophers. That makes them arguing like "bad priest".
I don't suppose I will get anything remotely like the Principia no
matter how many times I ask,
Thousand of pages of symbolic writing? That would not help.
but out of interest, what should I be asking him for?
Clear informal assumptions. He made a good try for his p-time.
That he does not understand (or really study) the rebuttal is his
problem, not yours.
Better always to focus on the points. You can always say: "sorry, I
don't understand". It is up to him to be more clear.
Again, if he thinks that you are stupid, that is his own problem, not
yours (unless he is your director of thesis of course, or your boss or
I'm sure there is something that is more "formal" than just a lot of
hand waving and nonsensical-seeming verbiage,
Yes. A clear theory, clear statements and clear means of verification,
like honest scientists and like serious philosophers, but unlike
anyone trying to convince that some statements are true or obvious.
Assumptions are the "obvious" things that we can try to refute.
while not being formal in the sense used by logicians.
Sure. In fact rigor is orthogonal to formalness. The logicians
distinction between formal and informal is very important for us,
though. We will come back on this.
Note that we can study informally the formal things, like in
mathematical logic. But we can also study formally some notion of
informalness, and that is what appears with the Bp & p logic (as with
the Bp & Dt & p) formal logics (S4Grz, X, Z, X*, etc.). That will be
important later. that motivates me even more to explain the modal logic.
