| 7559 | Every part of the universe is body, and non-body is not part of it [Hobbes] |
| Full Idea: The world is corporeal, that is to say, body...and every part of the universe is body, and that which is not body is no part of the universe. | |
| From: Thomas Hobbes (Leviathan [1651], IV.46) | |
| A reaction: [Hobbes concedes existence to visible spirits, but not invisible ones]. This is the kind of remark which got Hobbes hated. It is also the sort of thing that makes him the best candidate for the 'first modern man'. |
| 8580 | Materialism is (roughly) that two worlds cannot differ without differing physically [Lewis] |
| Full Idea: Final definition of 'Materialism': Among worlds where no natural properties alien to our world are instantiated, no two differ without differing physically; and two such worlds that are exactly alike physically are duplicates. | |
| From: David Lewis (New work for a theory of universals [1983], 'Min Mat') | |
| A reaction: This would presumably allow for an anomalous monist/property dualist view of mind, but not full dualism. But if there are no psychophysical laws, what stops the mental changing while the physical remains the same? |
