Hintikka's Thesis Revisited Nina Gierasimczuk, Jakub Szymanik Abstract: We discuss the thesis formulated by Hintikka (1973) that certain natural language sentences require non-linear quantification to express their meaning. Our basic assumption is that a criterion for adequacy of meaning representation is compatibility with sentence truth-conditions. This can be established by observing linguistic behavior of language users. We investigate sentences with combinations of quantifiers similar to Hintikka's examples and propose a novel alternative reading expressible by linear formulae. This interpretation is based on logical and philosophical observations. Moreover, we report on experiments showing that people tend to interpret sentences similar to Hintikka's sentence in a way consistent with our interpretation.
