7 ideas
12270 | Being is one [Melissus, by Aristotle] |
Full Idea: Being is one. | |
From: report of Melissus (fragments/reports [c.443 BCE]) by Aristotle - Topics 104b23 | |
A reaction: I can only really understand this in terms of physics, as the belief that ultimately there is one simple theory which explains everything. That project doesn't look terribly promising, despite the lovely simplifications of modern physics. |
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. |
23873 | Dividing history books into separate chapters is disastrous [Weil] |
Full Idea: The division of history textbooks into chapters will cost us many disastrous mistakes. | |
From: Simone Weil (Fragments [1936], p.131) | |
A reaction: Nice observation. The point is that we fail to grasp what really happened if we draw sharp lines across history. |
3059 | There is no real motion, only the appearance of it [Melissus, by Diog. Laertius] |
Full Idea: There is no such thing as real motion, but there only appears to be such. | |
From: report of Melissus (fragments/reports [c.443 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.4.3 |
5100 | The void is not required for change, because a plenum can alter in quality [Aristotle on Melissus] |
Full Idea: There is no need for void to be the cause of all change, because it is perfectly possible for a plenum to alter qualitatively (which is something Melissus overlooked). | |
From: comment on Melissus (fragments/reports [c.443 BCE]) by Aristotle - Physics 214a27 | |
A reaction: In modern physics this presumably gives us fluctuations in a force field. Motion is like a cat being digested by a python. The atomist claim that emptiness is needed if anything is to move still has intuitive appeal. |
456 | Nothing could come out of nothing [Melissus] |
Full Idea: If Nothing existed, in no way could anything come into being out of nothing. | |
From: Melissus (fragments/reports [c.443 BCE], B1), quoted by (who?) - where? |
