17596 | Coherence problems have positive and negative restraints; solutions maximise constraint satisfaction [Thagard] |
Full Idea: A coherence problem is a set of elements connected by positive and negative restraints, and a solution consists of partitioning the elements into two sets (accepted and rejected) in a way that maximises satisfaction of the constraints. | |
From: Paul Thagard (Coherence: The Price is Right [2012], p.42) | |
A reaction: I'm enthusiastic about this, as it begins to clarify the central activity of epistemology, which is the quest for best explanations. |
17597 | Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative [Thagard] |
Full Idea: I propose that there are six main kinds of coherence: explanatory, deductive, conceptual, analogical, perceptual, and deliberative. ...Epistemic coherence is a combination of the first five kinds, and ethics adds the sixth. | |
From: Paul Thagard (Coherence: The Price is Right [2012], p.43) | |
A reaction: Wonderful. Someone is getting to grips with the concept of coherence, instead of just whingeing about how vague it is. |
17598 | Explanatory coherence needs symmetry,explanation,analogy,data priority, contradiction,competition,acceptance [Thagard] |
Full Idea: Informally, a theory of explanatory coherence has the principles of symmetry, explanation, analogy, data priority, contradiction, competition and acceptance. | |
From: Paul Thagard (Coherence: The Price is Right [2012], p.44) | |
A reaction: [Thagard give a concise summary of his theory here] Again Thagard makes a wonderful contribution in an area where most thinkers are pessimistic about making any progress. His principles are very plausible. |
16292 | An explicit definition enables the elimination of what is defined [Halbach] |
Full Idea: Explicit definitions allow for a complete elimination of the defined notion (at least in extensional contexts). | |
From: Volker Halbach (Axiomatic Theories of Truth [2011], 1) | |
A reaction: If the context isn't extensional (concerning the things themselves) then we could define one description of it, but be unable to eliminate it under another description. Elimination is no the aim of an Aristotelian definition. Halbach refers to truth. |
16307 | Don't trust analogies; they are no more than a guideline [Halbach] |
Full Idea: Arguments from analogy are to be distrusted: at best they can serve as heuristics. | |
From: Volker Halbach (Axiomatic Theories of Truth [2011], 4) |
