| 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. |
| 5500 | Biologists see many organic levels, 'abstract' if seen from below, 'structural' if seen from above [Lycan] |
| Full Idea: Biologists don't split living things into a 'structural' level and an 'abstract' level; ..rather, they are organised at many levels, each level 'abstract' with respect to those beneath it, but 'structural' as it realises those levels above it. | |
| From: William Lycan (Introduction - Ontology [1999], p.9) | |
| A reaction: This is a very helpful distinction. Compare Idea 4601. It seems to fit well with the 'homuncular' picture of a hierarchical mind, and explains why there are so many levels of description available for mental life. |
| 5494 | 'Lightning is electric discharge' and 'Phosphorus is Venus' are synthetic a posteriori identities [Lycan] |
| Full Idea: There is such a thing as synthetic and a posteriori identity that is nonetheless genuine identity, as in lightning being electrical discharge, and the Morning Star being Venus. | |
| From: William Lycan (Introduction - Ontology [1999], p.5) | |
| A reaction: It is important to note that although these identities are synthetic a posteriori, that doesn't make them contingent. The early identity theorists like Smart seemed to think that it did. Kripke must be right that they are necessary identities. |
| 7566 | The Identity of Indiscernibles is really the same as the verification principle [Jolley] |
| Full Idea: Various writers have noted that the Identity of Indiscernibles is really tantamount to the verification principle. | |
| From: Nicholas Jolley (Leibniz [2005], Ch.3) | |
| A reaction: Both principles are false, because they are the classic confusion of epistemology and ontology. The fact that you cannot 'discern' a difference between two things doesn't mean that there is no difference. Things beyond verification can still be discussed. |
| 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. |
| 5496 | Functionalism has three linked levels: physical, functional, and mental [Lycan] |
| Full Idea: Functionalism has three distinct levels of description: a neurophysiological description, a functional description (relative to a program which the brain is realising), and it may have a further mental description. | |
| From: William Lycan (Introduction - Ontology [1999], p.6) | |
| A reaction: I have always thought that the 'levels of description' idea was very helpful in describing the mind/brain. I feel certain that we are dealing with a single thing, so this is the only way we can account for the diverse ways in which we discuss it. |
| 5499 | A mental state is a functional realisation of a brain state when it serves the purpose of the organism [Lycan] |
| Full Idea: Some theorists have said that the one-to-one correspondence between the organism and parts of its 'program' is too liberal, and suggest that the state and its functional role are seen teleologically, as functioning 'for' the organism. | |
| From: William Lycan (Introduction - Ontology [1999], p.9) | |
| A reaction: This seems an inevitable development, once the notion of a 'function' is considered. It has to be fitted into some sort of Aristotelian teleological picture, even if the functions are seen subjectively (by what?). Purpose is usually seen as evolutionary. |
| 5501 | People are trying to explain biological teleology in naturalistic causal terms [Lycan] |
| Full Idea: There is now a small but vigorous industry whose purpose is to explicate biological teleology in naturalistic terms, typically in terms of causes. | |
| From: William Lycan (Introduction - Ontology [1999], p.10) | |
| A reaction: This looks like a good strategy. In some sense, it seems clear that the moon has no purpose, but an eyeball has one. Via evolution, one would expect to reduce this to causation. Purposes are real (not subjective), but they are reducible. |
