| 14181 | Validity is where either the situation or the interpretation blocks true premises and false conclusion [Etchemendy, by Read] |
| Full Idea: The Representational account of validity says an argument is valid if there is no situation where the premises are true and the conclusion false. The Interpretation account says the premises are true and conclusion false under no interpretations. | |
| From: report of John Etchemendy (The Concept of Logical Consequence [1999]) by Stephen Read - Formal and Material Consequence 'Inval' | |
| A reaction: My immediate instinct is to want logic to be about situations, rather than interpretations. Situations are more about thought, where interpretations are more about language. I think our account of logic should have some applicability to animals. |
| 14180 | Etchemendy says fix the situation and vary the interpretation, or fix interpretations with varying situations [Etchemendy, by Read] |
| Full Idea: In Etchemendy's Interpretational Semantics (perhaps better called 'Substitutional') we keep the situation fixed and vary the interpretation; in Representational Semantics ('Modal'?) we keep interpretations fixed but consider varying situations. | |
| From: report of John Etchemendy (The Concept of Logical Consequence [1999]) by Stephen Read - Formal and Material Consequence 'Inval' | |
| A reaction: [compressed] These are semantic strategies for interpreting logic, so they are two ways you might go about assessing an argument. |
| 22518 | The actual must be possible, because it occurred [Aristotle] |
| Full Idea: Actual events are evidently possible, otherwise they would not have occurred. | |
| From: Aristotle (The Poetics [c.347 BCE], 1451b18) | |
| A reaction: [quoted online by Peter Adamson] Seems like common sense, but it's important to have Aristotle assert it. |
| 19520 | Evidentialism is not axiomatic; the evidence itself inclines us towards evidentialism [Conee] |
| Full Idea: Evidentialism does not support beginning epistemology by taking for granted that evidentialism is true. ...Rather, what potentially justifies belief in intial epistemic data and initial procedures of inquiry is the evidence itself. | |
| From: Earl Conee (First Things First [2004], 'Getting') | |
| A reaction: This sounds good. I much prefer talk of 'evidence' to talk of 'perceptions', because evidence has been licked into shape, and its significance has been clarified. That is the first step towards the coherence we seek. |
| 19521 | If pure guesses were reliable, reliabilists would have to endorse them [Conee] |
| Full Idea: Reliabilism would count pure guesses as good reasons if guessing were properly reliable. | |
| From: Earl Conee (First Things First [2004], 'Getting') | |
| A reaction: See D.H. Lawrence's short story 'The Rocking Horse Winner'. This objection strikes me as being so devastating that it is almost conclusive. Except that pure guesses are never ever reliable, over a decent period of time. |
| 19522 | More than actual reliability is needed, since I may mistakenly doubt what is reliable [Conee] |
| Full Idea: Sheer reliability does not justify belief. ...It may be, for instance, that we have strong though misleading reason to deny the method's reliability. | |
| From: Earl Conee (First Things First [2004], 'Circles') | |
| A reaction: That is, we accept a justification if we judge the method to be reliable, not if it IS reliable. I can disbelieve all the reliable information that arrives in my mind. People do that all the time! Hatred of experts! Support for internalism? |
| 19523 | Reliabilism is poor on reflective judgements about hypothetical cases [Conee] |
| Full Idea: An unrefined reliability theory does a poor job at capturing reflective judgements about hypothetical cases | |
| From: Earl Conee (First Things First [2004], 'Stroud's') | |
| A reaction: Reliability can only be a test for tried and tested ways. No one can say whether imagining a range of possibilities is reliable or not. Is prediction a reliable route to knowledge? |
| 16566 | Poetry is more philosophic than history, as it concerns universals, not particulars [Aristotle] |
| Full Idea: Poetry is something more philosophic and of graver import than history, since its statements are rather of universals, whereas those of history are singulars. | |
| From: Aristotle (The Poetics [c.347 BCE], 1451b05) | |
| A reaction: Hm. Characters in great novels achieve universality by being representated very particularly. Great depth of mind seems required to be a poet, but less so for a historian (though there is, I presume, no upward limit on the possible level of thought). |
