7 ideas
18351 | Propositions are made true, in virtue of something which explains its truth [Lowe] |
Full Idea: If a proposition is 'made' true, it has to be true 'in virtue of' something, meaning a relationship of metaphysical explanation. Thus a true proposition must have truth conferred on it in some way that explains how it gets to be true. | |
From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.202) | |
A reaction: It is good to ask what we mean by 'makes'. I like essentialist explanations, but this may be misplaced. Observing that y makes x true seems to be rather less than actually explaining how it does it. What would such explanations look like? |
18353 | Modes are beings that are related both to substances and to universals [Lowe] |
Full Idea: Modes are real beings that stand in non-contingent formal ontological relations both to individual substances and to immanent universals. | |
From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.212) | |
A reaction: Not sure I understand this, but I pass it on. 'Modes' seem to invite the Razor, if we already have substances and universals. I am no clear about 'instantiation' because I now have the word 'mode' to play with. |
18352 | Tropes have existence independently of any entities [Lowe] |
Full Idea: Pure trope theorists must apparently hold that each trope has its identity underivatively, not that it depends for it on or owes it to other entities of any sort. | |
From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.207) | |
A reaction: Lowe defends dependent 'modes' of things, against independent 'tropes'. Good, but he then has to say what the thing is (a modeless 'substance'?), because it can't just be a bundle of modes or tropes. |
21687 | It seems obvious to prefer the simpler of two theories, on grounds of beauty and convenience [Quine] |
Full Idea: It is not to be wondered that theory makers seek simplicity. When two theories are equally defensible on other counts, certainly the simpler of the two is to be preferred on the score of both beauty and convenience. | |
From: Willard Quine (On Simple Theories of a Complex World [1960], p.255) | |
A reaction: A simple application of Ockham's Razor. Quine goes on to nicely deconstruct what is involved in simplicity, and identify a certain amount of dubious prejudice in the concept. |
21688 | There are four suspicious reasons why we prefer simpler theories [Quine] |
Full Idea: We prefer simpler theories through wishful thinking, or a bias which slants the data, or a bias where the simpler hypothesis is more open to confirmation, or simpler hypotheses tolerating wider deviations in score-keeping. | |
From: Willard Quine (On Simple Theories of a Complex World [1960], p.258) | |
A reaction: [a compression of his summary of the paper] Quine is not dismissing our preference for simpler theories, but just very nicely inviting us to focus of aspects about which we should be cautious. |
7861 | Libet says the processes initiated in the cortex can still be consciously changed [Libet, by Papineau] |
Full Idea: Libet himself points out that the conscious decisions still have the power to 'endorse' or 'cancel', so to speak, the processes initiated by the earlier cortical activity: no action will result if the action's execution is consciously countermanded. | |
From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by David Papineau - Thinking about Consciousness 1.4 | |
A reaction: This is why Libet's findings do not imply 'epiphenomenalism'. It seems that part of a decisive action is non-conscious, undermining the all-or-nothing view of consciousness. Searle tries to smuggle in free will at this point (Idea 3817). |
6660 | Libet found conscious choice 0.2 secs before movement, well after unconscious 'readiness potential' [Libet, by Lowe] |
Full Idea: Libet found that a subject's conscious choice to move was about a fifth of a second before movement, and thus later than the onset of the brain's so-called 'readiness potential', which seems to imply that unconscious processes initiates action. | |
From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9 | |
A reaction: Of great interest to philosophers! It seems to make conscious choices epiphenomenal. The key move, I think, is to give up the idea of consciousness as being all-or-nothing. My actions are still initiated by 'me', but 'me' shades off into unconsciousness. |
