Someone standing in a doorway seems to be both in and not-in the room [Priest,G, by Sorensen]
|
|
Full Idea:
Priest says there is room for contradictions. He gives the example of someone in a doorway; is he in or out of the room. Given that in and out are mutually exclusive and exhaustive, and neither is the default, he seems to be both in and not in.

From:
report of Graham Priest (What is so bad about Contradictions? [1998]) by Roy Sorensen - Vagueness and Contradiction 4.3
|
|
A reaction:
Priest is a clever lad, but I don't think I can go with this. It just seems to be an equivocation on the word 'in' when applied to rooms. First tell me the criteria for being 'in' a room. What is the proposition expressed in 'he is in the room'?

The old 'influx' view of causation says it is a flow of accidental properties from A to B [Suárez, by Jolley]
|
|
Full Idea:
The 'influx' model of causation says that causes involve a process of contagion, as it were; when the kettle boils, the gas infects the water inside the kettle with its own 'individual accident' of heat, which literally flows from one to the other.

From:
report of Francisco Suárez (works [1588]) by Nicholas Jolley - Leibniz Ch.2
|
|
A reaction:
This nicely captures the scholastic target of Hume's sceptical thinking on the subject. However, see Idea 2542, where the idea of influx has had a revival. It is hard to see how the water could change if it didn't 'catch' something from the gas.
