| 5495 | Instances of pain are physical tokens, but the nature of pain is more abstract [Putnam, by Lycan] |
| Full Idea: In machine functionalism, pain tokens (individual instances of pain) are identical with particular neurophysiological states, but pain itself, the kind, universal, or 'type', can be identified only with something more abstract. | |
| From: report of Hilary Putnam (The Mental Life of Some Machines [1967]) by William Lycan - Introduction - Ontology p.6 | |
| A reaction: This is where the "what is it like?" question seems important. Pain doesn't seem like a physical object, or an abstract idea. Personally I think the former is more likely to be correct than the latter. Causation by pain is not like causation by gravity. |
| 4001 | The meaning of a word contains all its possible uses as well as its actual ones [Nagel] |
| Full Idea: The meaning of a word contains all its possible uses, true and false, not only its actual ones. | |
| From: Thomas Nagel (What Does It All Mean? [1987], Ch.5) | |
| A reaction: It has always seemed to me that meaning is not use, because you can't use it if it hasn't already got a meaning. What use is a meaningless word? |
| 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. |
