15327 | Kripke's semantic theory has actually inspired promising axiomatic theories [Kripke, by Horsten] |
Full Idea: Kripke has a semantic theory of truth which has inspired promising axiomatic theories of truth. | |
From: report of Saul A. Kripke (Outline of a Theory of Truth [1975]) by Leon Horsten - The Tarskian Turn 01.2 | |
A reaction: Feferman produced an axiomatic version of Kripke's semantic theory. |
15343 | Kripke offers a semantic theory of truth (involving models) [Kripke, by Horsten] |
Full Idea: One of the most popular semantic theories of truth is Kripke's theory. It describes a class of models which themselves involve a truth predicate (unlike Tarski's semantic theory). | |
From: report of Saul A. Kripke (Outline of a Theory of Truth [1975]) by Leon Horsten - The Tarskian Turn 02.3 | |
A reaction: The modern versions explored by Horsten are syntactic versions of this, derived from Feferman's axiomatisation of the Kripke theory. |
14967 | Certain three-valued languages can contain their own truth predicates [Kripke, by Gupta] |
Full Idea: Kripke showed via a fixed-point argument that certain three-valued languages can contain their own truth predicates. | |
From: report of Saul A. Kripke (Outline of a Theory of Truth [1975]) by Anil Gupta - Truth | |
A reaction: [Gupta also cites Martin and Woodruff 1975] It is an odd paradox that truth can only be included if one adds a truth-value of 'neither true nor false'. The proposed three-valued system is 'strong Kleene logic'. |
14966 | The Tarskian move to a metalanguage may not be essential for truth theories [Kripke, by Gupta] |
Full Idea: Kripke established that, contrary to the prevalent Tarskian dogma, attributions of truth do not always force a move to a metalanguage. | |
From: report of Saul A. Kripke (Outline of a Theory of Truth [1975], 5.1) by Anil Gupta - Truth | |
A reaction: [Gupta also cites Martin and Woodruff 1975] |
16328 | Kripke classified fixed points, and illuminated their use for clarifications [Kripke, by Halbach] |
Full Idea: Kripke's main contribution was …his classification of the different consistent fixed points and the discussion of their use for discriminating between ungrounded sentences, paradoxical sentences, and so on. | |
From: report of Saul A. Kripke (Outline of a Theory of Truth [1975]) by Volker Halbach - Axiomatic Theories of Truth 15.1 |
23688 | Noncognitivism tries to avoid both naturalism and mysterious morality [Hacker-Wright] |
Full Idea: Noncognitivism is an attempt to avoid the alleged problems of naturalism without the mysteries of Moore's non-naturalism. | |
From: John Hacker-Wright (Philippa Foot's Moral Thought [2013], 1) | |
A reaction: R.M. Hare is the best example of this approach. Moore's Open Question argument was said to prove the Naturalistic Fallacy, which imagined that morality could be a feature of nature. It led Moore to platonism. I prefer Philippa Foot. |
7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
