3789 | The more reasons that compel me, the freer I am [Descartes] |
Full Idea: I move the more freely towards an object in proportion to the number of reasons which compel me. | |
From: René Descartes (Letter to Mersenne [1642]) |
7876 | Even if we identify pain with neural events, we can't explain why those neurons cause that feeling [Levine, by Papineau] |
Full Idea: Materialists identify pain with the firing of nociceptive-specific neurons in the parietal cortex. Even so, Levine argues, we will still lack any explanation of why nociceptive-specific neurons yield pain. | |
From: report of Joseph Levine (Purple Haze [2001]) by David Papineau - Thinking about Consciousness 5.1 | |
A reaction: [Proposed by Levine in 1983] I don't think we need to instantly go dualist when faced with this, but we may all eventually have to concede a bit of mysterianism. The explanation may be holistic (and hence hopelessly complex). |
7877 | Only phenomenal states have an explanatory gap; water is fully explained by H2O [Levine, by Papineau] |
Full Idea: Levine says the explanatory gap is peculiar to phenomenal states. Once water has been identified with H2O, or temperature with mean kinetic energy, we do not continue to ask why H2O yields water, or why mean kinetic energy yields temperature. | |
From: report of Joseph Levine (Purple Haze [2001]) by David Papineau - Thinking about Consciousness 5.1 | |
A reaction: Everything is mysterious if you think about if for long enough. What about a representational gap? Why do those neurons represent that tree (if the neurons aren't tree-shaped)? To understand qualia, we must understand the whole brain, I suspect. |
7878 | Materialism won't explain phenomenal properties, because the latter aren't seen in causal roles [Papineau on Levine] |
Full Idea: We cannot give materialist explanations of why brain yields phenomenal properties because phenomenal concepts are not associated with descriptions of causal roles in the same way as pre-theoretical terms in other areas of science. | |
From: comment on Joseph Levine (Purple Haze [2001]) by David Papineau - Thinking about Consciousness 5.1 | |
A reaction: I think Papineau has part of the answer, and I certainly like his notion of Conceptual Dualism, but if qualia are physical, there must be a physical account of how they acquire their properties. I think the whole brain needs to be understood first. |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
