The symbols don't have an indexical reference but they have meaning in so far as they carry the information that p is not hyphen or q. Is that not meaning enough??
There is a serious problem with the hypothesis at the end of this clip. It implies that axioms are temporal, and change truth in time. Time would have to be discrete and be behind the laws of physics rather in them. Particles react with what is contingently around them, therefore the truth of such an axiom would be contingent on the temporal existence of other axioms which is an absurdity. Such an idea of time contradicts relativity.
...very good up til this point IMHO. I think the use of hyphens is a bad idea because they look like minus signs. I use tear drops or leaf shapes when I teach this.

@ccowws Who says relativity is correct and all encompassing?

@TheWeirdStore I think he just used those because those were the ones used in the book.
