There are many psychophysicals laws - about the effects of sweets, colours and soft cushions [Mellor/Crane]
|
|
Full Idea:
There are many psychophysical laws, linking sensations to non-mental features of those who have them; the industries of anaesthetics, scents, narcotics, sweeteners, coloured paints, loudspeakers and soft cushions depend on them.
|
|
From:
DH Mellor / T Crane (There is no question of physicalism [1990], p.198)
|
|
A reaction:
It may be expressing it a little strongly to call these 'laws', but they are certainly reliable regularities, and they are probably enough to undermine Davidson's claim that such laws don't exist.

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.
