|That clause: partial sentence, expresses e.g. a belief (propositional attitude). This content is intensional, i.e. it is not objective. For some authors, the partial sentence "that it is raining" is the name of the sentence "It is raining".|

Definition content: be the meaning of the that-clause- it is about contents in this book - different objects (sentences) can have the same content.
That-clause/intension/Cresswell: the intension of the that-clause is not always equal to the intension of the complement clause - (the clause following the "that") - iterated propositional attitude: Problem: occurs when the most outside "that" operates on the sense (structure) of the complement clause - analogously: the plus sign would then contain itself as one of its arguments.
Propositional attitude/attribution/that-clause/truth conditions/content/Cresswell: thesis: the truth conditions of clauses with propositional attitudes are determined by the contents of the that-clauses - that is the only thing I want.
More than just the truth conditions of the complement clauses are involved in the attribution of propositional attitudes.
Naked infinitive/Cresswell: behaves quite differently from the that-clause - E.g. a) Fred saw Betty coming in - b) Fred saw Betty coming in and he saw Sally smoking or not smoking - Barwise/Perry: one cannot go from a) to b) Cresswell dito - naked infinitives have no proposition as a semantic value but a situation type - event: there are no disjunctive events - Negation of event/negative event: also not possible: - E.g. "Fred saw Betty not smoking" - events/Cresswell: are only used because some expressions do not behave as whole sentences.
