| 3536 | Supervenient properties must have matching base properties [Kim] |
| Full Idea: Each supervenient property necessarily has a coextensive property in the base family. | |
| From: Jaegwon Kim (Concepts of supervenience [1984], §5) | |
| A reaction: This is presumably the minimum requirement for a situation of supervenience. How do you decide which property is the 'base' property? Do we just mean that the base causes the other, but not vice versa? |
| 6382 | The 'grain problem' says physical objects are granular, where sensations appear not to be [Sellars, by Polger] |
| Full Idea: Sellars' Grain Problem contended that it was a problem for materialism that physical objects have a granularity whereas sensations are homogeneous and without grain. | |
| From: report of Wilfrid Sellars (Empiricism and the Philosophy of Mind [1956], Ch. n22) by Thomas W. Polger - Natural Minds Ch.1 n22 | |
| A reaction: This doesn't strike me as a serious problem. I assume that my sensations are granular, but at a level too fine for me to introspect. There are three hundred trillion connections in the brain (Idea 2952), a lot of them involved in sensations. |
| 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. |
