[QUOTE="verty, post: 4524179, member: 54975"] I think what you are asking is, what allows us to apply the compactness theorem to the particular case of maps and colourings? The compactness theorem was proved by Kurt Gödel using the completeness theorem, which says that truth of a wff is very regular, it can be calculated (proved) from the truth values of the parts of the formula. But how do we know that this is true for maps and colourings? Is it not possible that truth works differently here? In a way, this question is about whether truth is always regular. I don't know how to answer this but perhaps reading [url=http://plato.stanford.edu/entries/truth-axiomatic/]this[/url] can help. [/QUOTE]
