10 ideas
19259 | If 2-D conceivability can a priori show possibilities, this is a defence of conceptual analysis [Vaidya] |
Full Idea: Chalmers' two-dimensional conceivability account of possibility offers a defence of a priori conceptual analysis, and foundations on which a priori philosophy can be furthered. | |
From: Anand Vaidya (Understanding and Essence [2010], Intro) | |
A reaction: I think I prefer Williamson's more scientific account of possibility through counterfactual conceivability, rather than Chalmers' optimistic a priori account. Deep topic, though, and the jury is still out. |
19262 | Essential properties are necessary, but necessary properties may not be essential [Vaidya] |
Full Idea: When P is an essence of O it follows that P is a necessary property of O. However, P can be a necessary property of O without being an essence of O. | |
From: Anand Vaidya (Understanding and Essence [2010], 'Knowledge') | |
A reaction: This summarises the Kit Fine view with which I sympathise. However, I dislike presenting essence as a mere list of properties, which is only done for the convenience of logicians. But was Jessie Owens a great athlete after he lost his speed? |
6215 | 'Contingent' means that the cause is unperceived, not that there is no cause [Hobbes] |
Full Idea: For contingent, men do not mean that which hath no cause, but that which hath not for cause any thing that we perceive, as when a traveller meets a shower, they both had sufficient causes, but they didn't cause one another, so we say it was contingent. | |
From: Thomas Hobbes (Of Liberty and Necessity [1654], §95) | |
A reaction: Contingent nowadays means 'might not have happened', or 'does not happen in all possible worlds'. Personally I share Hobbes' doubts about the concept of contingency, and this is quite a good account of the misunderstanding. |
19267 | Define conceivable; how reliable is it; does inconceivability help; and what type of possibility results? [Vaidya] |
Full Idea: Conceivability as evidence for possibility needs four interpretations. How is 'conceivable' defined or explained? How strongly is the idea endorsed? How does inconceivability fit in? And what kind of possibility (logical, physical etc) is implied? | |
From: Anand Vaidya (Understanding and Essence [2010], 'Application') | |
A reaction: [some compression] Williamson's counterfactual account helps with the first one. The strength largely depends on whether your conceptions are well informed. Inconceivability may be your own failure. All types of possibility can be implied. |
19268 | Inconceivability (implying impossibility) may be failure to conceive, or incoherence [Vaidya] |
Full Idea: If we aim to derive impossibility from inconceivability, we may either face a failure to conceive something, or arrive at a state of incoherence in conceiving. | |
From: Anand Vaidya (Understanding and Essence [2010], 'Application') | |
A reaction: [summary] Thus I can't manage to conceive a multi-dimensional hypercube, but I don't even try to conceive a circular square. In both cases, we must consider whether the inconceivability results from our own inadequacy, rather than from the facts. |
19265 | Can you possess objective understanding without realising it? [Vaidya] |
Full Idea: Is it possible for an individual to possess objectual understanding without knowing they possess the objectual understanding? | |
From: Anand Vaidya (Understanding and Essence [2010], 'Objections') | |
A reaction: Hm. A nice new question to loose sleep over. We can't demand a regress of meta-understandings, so at some point you just understand. Birds understand nests. Equivalent: can you understand P, but can't explain P? Skilled, but inarticulate. |
19260 | Gettier deductive justifications split the justification from the truthmaker [Vaidya] |
Full Idea: In the Gettier case of deductive justification, what we have is a separation between the source of the justification and the truthmaker for the belief. | |
From: Anand Vaidya (Understanding and Essence [2010], 'Distinction') | |
A reaction: A very illuminating insight into the Gettier problem. As a fan of truthmakers, I'm wondering if this might quickly solve it. |
19266 | In a disjunctive case, the justification comes from one side, and the truth from the other [Vaidya] |
Full Idea: The disjunctive belief that 'either Jones owns a Ford or Brown is in Barcelona', which Smith believes, derives its justification from the left disjunct, and its truth from the right disjunct. | |
From: Anand Vaidya (Understanding and Essence [2010], 'Application') | |
A reaction: The example is from Gettier's original article. Have we finally got a decent account of the original Gettier problem, after fifty years of debate? Philosophical moves with delightful slowness. |
19264 | Aboutness is always intended, and cannot be accidental [Vaidya] |
Full Idea: A representation cannot accidentally be about an object. Aboutness is in general an intentional relation. | |
From: Anand Vaidya (Understanding and Essence [2010], 'Objections') | |
A reaction: 'Intentional' with a 't', not with an 's'. This strikes me as important. Critics dislike the idea of 'representation' because if you passively place a representation and its subject together, what makes the image do the representing job? Answer: I do! |
20959 | Concepts are only analytic once the predicate is absorbed into the subject [Schleiermacher] |
Full Idea: The difference between analytic and synthetic judgements is an unimportant fluid one. 'Ice melts' is analytic if it is already taken up into the concept of ice, and synthetic if not yet taken up. It is just a different state of the formation of concepts. | |
From: Friedrich Schleiermacher (Dialektik [1833], p.563), quoted by Andrew Bowie - Introduction to German Philosophy 8 'Scientific' | |
A reaction: [compressed] I wonder if Quine ever encountered this quotation. The idea refers to Kant's notion of analyticity, and makes the good point that predicates only become 'contained in the subject' once the situation is very familiar. |
