|Existence||Russell III 127
Existence/Russell: the term existence can only be applied usefully to propositional functions.
Defintion existence/Russell: There is an argument for a certain propositional function, for which it is true - according to Russell, there are only atomic facts and absolutely simple individuals (logical atomism).
Russell VI 76
Predicate/propositional function/Russell: some predicates, for example, Existence can only be attributed to statement functions (or classes), but not to statements: E.g. "People are numerous, therefore Socrates is numerous". - Therefore, you also know that there are people in Timbuktu, without knowing them: the existence theorem is about a class, not individuals.
Tugendhat I 377
Existence/Russell/Tugendhat: Russell interprets the singular predicative statement as an existential proposition and this as a general (general) statement. - That was already anticipated by Kant and Frege. - Then E.g. "The present King of France is bald", etc. is always wrong -> generality.
Tugendhat II 43
Existence/Russell: one can only talk about existent things - but past and future are also existent.
