Single Idea 17597

[filed under theme 2. Reason / A. Nature of Reason / 6. Coherence ]

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.

Gist of Idea

Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative

A Reaction

Wonderful. Someone is getting to grips with the concept of coherence, instead of just whingeing about how vague it is.


The 13 ideas from Paul Thagard

Coherence problems have positive and negative restraints; solutions maximise constraint satisfaction [Thagard]
Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative [Thagard]
Explanatory coherence needs symmetry,explanation,analogy,data priority, contradiction,competition,acceptance [Thagard]
Bayesian inference is forced to rely on approximations [Thagard]
The best theory has the highest subjective (Bayesian) probability? [Thagard]
Verisimilitude comes from including more phenomena, and revealing what underlies [Thagard]
Neither a priori rationalism nor sense data empiricism account for scientific knowledge [Thagard]
1: Coherence is a symmetrical relation between two propositions [Thagard, by Smart]
2: An explanation must wholly cohere internally, and with the new fact [Thagard, by Smart]
3: If an analogous pair explain another analogous pair, then they all cohere [Thagard, by Smart]
4: For coherence, observation reports have a degree of intrinsic acceptability [Thagard, by Smart]
5: Contradictory propositions incohere [Thagard, by Smart]
6: A proposition's acceptability depends on its coherence with a system [Thagard, by Smart]
