Single Idea 8413

[filed under theme 26. Natural Theory / C. Causation / 5. Direction of causation ]

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.

Gist of Idea

Cause must come first in propagations of causal interactions, but interactions are simultaneous

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.


The 19 ideas with the same theme [explain the past-to-future direction of causes]:

People assume events cause what follows them [Aristotle]
A cause can exist without its effect, but the effect cannot exist without its cause [Aquinas]
A theory of causal relations yields an asymmetry which defines the direction of time [Reichenbach, by Salmon]
p is a cause and q an effect (not vice versa) if manipulations of p change q [Wright,GHv]
We can imagine controlling floods by controlling rain, but not vice versa [Wright,GHv]
With diseases we easily trace a cause from an effect, but we cannot predict effects [Anscombe]
Cause must come first in propagations of causal interactions, but interactions are simultaneous [Salmon]
Humean accounts of causal direction by time fail, because cause and effect can occur together [Harré/Madden]
A theory of causation should explain why cause precedes effect, not take it for granted [Lewis, by Field,H]
I reject making the direction of causation axiomatic, since that takes too much for granted [Lewis]
There are few traces of an event before it happens, but many afterwards [Lewis, by Horwich]
We can only reduce the direction of causation to the direction of time if we are realist about the latter [Tooley]
Physical laws are largely time-symmetric, so they make a poor basis for directional causation [Field,H]
Identifying cause and effect is not just conventional; we explain later events by earlier ones [Field,H]
The only reason for adding the notion of 'cause' to fundamental physics is directionality [Field,H]
If the concept of a cause says it precedes its effect, that rules out backward causation by definition [Lowe]
At least four rivals have challenged the view that causal direction is time direction [Schaffer,J]
Causal order must be temporal, or else causes could be blocked, and time couldn't be explained [Schaffer,J]
Causal order is not temporal, because of time travel, and simultanous, joint or backward causes [Schaffer,J]
