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'?

All legislators invoke God in support of extraordinary laws, because their justification is not obvious [Machiavelli]
|
|
Full Idea:
There has never been a single legislator who, in proposing extraordinary laws, did not have recourse to God, for otherwise they would not be accepted, since many benefits known to a prudent man do not have evident persuasive reasons.
|
|
From:
Niccolo Machiavelli (The Discourses [1520], 1.11), quoted by Jean-Jacques Rousseau - The Social Contract (tr Cress) II.7 n8
|
|
A reaction:
It does seem to be an important role for God and state religion, to give support to decisions and laws which might not be intrinsically popular.

Rulers should preserve the foundations of religion, to ensure good behaviour and unity [Machiavelli]
|
|
Full Idea:
It is the duty of the rulers of a republic or a kingdom to preserve the foundations of the religion they hold; if they do this, it will be an easy thing for them to keep their state religious, and consequently good and united.
|
|
From:
Niccolo Machiavelli (The Discourses [1520], I.12)
|
|
A reaction:
This is the germ of Marx's view, that the sole role of religion is political, as a tool used by the ruling classes to keep the populace in their place. The same idea can be found in Critias (Idea 542). But what is wrong with some central moral guidance?

A causal interaction is when two processes intersect, and correlated modifications persist afterwards [Salmon]
|
|
Full Idea:
When two processes intersect, and they undergo correlated modifications which persist after the intersection, I shall say that the intersection is a causal interaction. I take this as a fundamental causal concept.
|
|
From:
Wesley Salmon (Causality: Production and Propagation [1980], §4)
|
|
A reaction:
There may be a problem individuating processes, just as there is for events. I like this approach to causation, which is ontologically sparse, and fits in with the scientific worldview. Change of properties sounds precise, but isn't. Stick to processes.

Cause must come first in propagations of causal interactions, but interactions are simultaneous [Salmon]
|
|
Full Idea:
In a typical cause-effect situation (a 'propagation') cause must precede effect, for propagation over a finite time interval is an essential feature. In an 'interaction', an intersection of processes resulting in change, we have simultaneity.
|
|
From:
Wesley Salmon (Causality: Production and Propagation [1980], §8)
|
|
A reaction:
This takes the direction of time as axiomatic, and quite right too. Salmon isn't addressing the real difficulty, though, which is that the resultant laws are usually held to be time-reversible, which is a bit of a puzzle.

Instead of localised events, I take enduring and extended processes as basic to causation [Salmon]
|
|
Full Idea:
I propose to approach causality by taking processes rather than events as basic entities. Events are relatively localised in space and time, while processes have much greater temporal duration, and, in many cases, much greater spatial extent.
|
|
From:
Wesley Salmon (Causality: Production and Propagation [1980], §2)
|
|
A reaction:
This strikes me as an incredibly promising proposal, not just in our understanding of causation, but for our general metaphysics and understanding of nature. See Idea 4931, for example. Vague events and processes blend into one another.
