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. |
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] |
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'. |
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 |
3016 | Even the gods cannot strive against necessity [Pittacus, by Diog. Laertius] |
Full Idea: Even the gods cannot strive against necessity. | |
From: report of Pittacus (reports [c.610 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 01.5.4 |
5996 | Critolaus redefined Aristotle's moral aim as fulfilment instead of happiness [Critolaus, by White,SA] |
Full Idea: Critolaus reformulated Aristotelian theory by defining happiness as a 'fulfilment' (sumplêrôma) of psychic, physical, and external goods, where virtue vastly outweighs the rest. | |
From: report of Critolaus (fragments/reports [c.170 BCE]) by Stephen A. White - Critolaus | |
A reaction: The sounds more like an attempt at clarification than a real change of Peripatetic doctrine. Occasionally 'fulfilment' is offered as a translation for eudaimonia. Maybe we should just take up Critolaus' suggestion when we are discussing Aristotle. |
