The principle that logical validity exists on a spectrum between absolute and relative, with infinite gradations and multiple dimensions. Under this law, an argument isn't simply valid or invalid—it's valid to some degree, in some logical systems, under some interpretations, for some purposes. The law of spectral validity recognizes that validity is not binary but continuous, that arguments can be more or less valid depending on the standards applied, and that the question isn't "is it valid?" but "where on the spectrum of validity does this argument fall?" This law is essential for understanding debates between different logical frameworks, where each side's arguments are valid within their own system but may appear invalid in another.
