Single Idea 8402

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

Full Idea

Although it is true that the notion of 'cause' is not needed in fundamental physics, even statistical physics, still directionality considerations don't preclude this notion from being consistently added to fundamental physics.

Gist of Idea

The only reason for adding the notion of 'cause' to fundamental physics is directionality

A Reaction

This only makes sense if the notion of cause already has directionality built into it, which I think is correct. The physicist might reply that they don't care about directionality, but the whole idea of an experiment seems to depend on it (Idea 8363).

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]
