7. Existence / A. Nature of Existence / 1. Nature of Existence
11008 Existence is not a first-order property, but the instantiation of a property [Frege, by Read]
     Full Idea: When Kant said that existence was not a property, what he meant was, according to Frege, that existence is not a first-order property - it is not a property of individuals but a property of properties, that the property has an instance.
     From: report of Gottlob Frege (Begriffsschrift [1879]) by Stephen Read - Thinking About Logic Ch.5
7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact
18737 There are no positive or negative facts; these are just the forms of propositions [Wittgenstein]
     Full Idea: There are no positive or negative facts. 'Positive' and 'negative' refer to the form of propositions, and not to the facts which verify or falsify them.
     From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C XIII)
     A reaction: Personally I think if we are going to allow the world to be full of 'facts', then there are negative, conjunctive, disjunctive and hypothetical facts.
