Empiricists deny what is unobservable, and reject objective modality [Fraassen]
|
|
Full Idea:
To be an empiricist is to withhold belief in anything that goes beyond the actual, observable phenomena, and to recognise no objective modality in nature.
|
|
From:
Bas C. van Fraassen (The Scientific Image [1980], p.202), quoted by J Ladyman / D Ross - Every Thing Must Go 2.3.1
|
|
A reaction:
To only believe in what is actually observable strikes me as ridiculous. It might be, though, that we observe modality, in observing dispositions. If you pull back a bowstring, you feel the possibilities.

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.

God must be fit for worship, but worship abandons morally autonomy, but there is no God [Rachels, by Davies,B]
|
|
Full Idea:
Rachels argues 1) If any being is God, he must be a fitting object of worship, 2) No being could be a fitting object of worship, since worship requires the abandonment of one's role as an autonomous moral agent, so 3) There cannot be a being who is God.
|
|
From:
report of James Rachels (God and Human Attributes [1971], 7 p.334) by Brian Davies - Introduction to the Philosophy of Religion 9 'd morality'
|
|
A reaction:
Presumably Lionel Messi can be a fitting object of worship without being God. Since the problem is with being worshipful, rather than with being God, should I infer that Messi doesn't exist?
