 As a rule, informational independence is not indicated syntactically in  English.[93]  Methodological consequences of this fact are discussed in Hintikka (1990), where he tentatively puts forward the Syntactic Silence Thesis, according to which sufficiently radical cross-categorical phenomena are not likely to be marked syntactically in natural languages. Evidence for this thesis would, for its part, be evidence against the sufficiency of syntax-oriented approaches to semantics.
