| 8616 | How can multiple statements, none of which is tenable, conjoin to yield a tenable conclusion? [Elgin] |
| Full Idea: How can multiple statements, none of which is tenable, conjoin to yield a tenable conclusion? How can their relation to other less than tenable enhance their tenability? | |
| From: Catherine Z. Elgin (Non-foundationalist epistemology [2005], p.157) | |
| A reaction: Her example is witnesses to a crime. Bayes Theorem appears to deal with individual items. "The thief had green hair" becomes more likely with multiple testimony. This is a very persuasive first step towards justification as coherence. |
| 8617 | Statements that are consistent, cotenable and supportive are roughly true [Elgin] |
| Full Idea: The best explanation of coherence (where the components of a coherent account must be mutually consistent, cotenable and supportive) is that the account is at least roughly true. | |
| From: Catherine Z. Elgin (Non-foundationalist epistemology [2005], p.158) | |
| A reaction: Note that she is NOT employing a coherence account of truth (which I take to be utterly wrong). It is notoriously difficult to define coherence. If the components must be 'tenable', they have epistemic status apart from their role in coherence. |
| 18151 | Could we replace sets by the open sentences that define them? [Chihara, by Bostock] |
| Full Idea: Chihara proposes to replace all sets by reference to the open sentences that define them. | |
| From: report of Charles Chihara (Ontology and the Vicious Circle Principle [1973]) by David Bostock - Philosophy of Mathematics 9.B.4 | |
| A reaction: This depends on predicativism, because that stipulates the definitions will be available (cos if it ain't definable it ain't there). Chihara went on to define the open sentences in terms of the possibility of uttering them. Cf. propositional functions. |
| 8618 | Coherence is a justification if truth is its best explanation (not skill in creating fiction) [Elgin] |
| Full Idea: The best explanation of the coherence of 'Middlemarch' lies in the novelist's craft. Coherence conduces to epistemic acceptability only when the best explanation of the coherence of a constellation of claims is that they are (at least roughly) true. | |
| From: Catherine Z. Elgin (Non-foundationalist epistemology [2005], p.160) | |
| A reaction: Yes. This combines my favourite inference to the best explanation (the favourite tool of us realists) with coherence as justification, where coherence can, crucially, have a social dimension. I begin to think this is the correct account of justification. |
| 18033 | The meaning of a representation is its role in thought, perception or decisions [Block] |
| Full Idea: According to conceptual role semantics, the meaning of a representation is the role of that representation in the cognitive life of the agent, for example, in perception, thought and decision-making. | |
| From: Ned Block (Semantics, Conceptual Role [1998]) | |
| A reaction: I never believe theories of this kind, because I always find myself asking 'what is the nature of this representation which enables it to play this role?'. |
