21777 | Negation of negation doubles back into a self-relationship [Hegel, by Houlgate] |
Full Idea: For Hegel, the 'negation of negation' is negation that, as it were, doubles back on itself and 'relates itself to itself'. | |
From: report of Georg W.F.Hegel (works [1812]) by Stephen Houlgate - An Introduction to Hegel 6 'Space' | |
A reaction: [ref VNP 1823 p.108] Glad we've cleared that one up. |
16416 | The quantifier in logic is not like the ordinary English one (which has empty names, non-denoting terms etc) [Hofweber] |
Full Idea: The inferential role of the existential quantifier in first order logic does not carry over to the existential quantifier in English (we have empty names, singular terms that are not even in the business of denoting, and so on). | |
From: Thomas Hofweber (Ambitious, yet modest, Metaphysics [2009], 2) |
