It definition generalises the latest informal idea sketched regarding Suzy and you may Billy

is an active causal route because when we hold BH fixed at its actual value (Billys rock doesnt hit the bottle), BS counterfactually depends on ST. By contrast, the route is not active because when we hold SH fixed at its actual value (Suzys rock does hit the bottle), BS does not counterfactually depend on BT.

In terms of the notion of a dynamic causal station, Hitchcock defines actual otherwise token causation regarding the following terms and conditions:

(10) If c and e are distinct actual events and X and Z are binary variables whose values represent the occurrence and non-occurrence of these events, then c is a cause of e if and only if there is an active causal route from X to Z in an appropriate causal model .

Lewis resort so you can quasi-dependency because the shattering of the container (e) cannot counterfactually depend on Suzys place (c), compliment of what would features taken place had she perhaps not thrown (viz, Billys material will have shattered the fresh new bottles instead)

As mentioned, (10) does not handle cases of shaped overdetermination as when Suzy and you can Billy one another put its rocks alone, for each and every throw is enough on the container to split, and one another stones hit the package very neither place preempts the fresh most other, since none put is found on a working channel while the defined in (9). To manage for example times, Hitchcock weakens (10) by replacement new ‘effective station in (10) on notion of good weakly productive station (2001: 290). The quintessential idea right here there is good weakly energetic channel between X and you may Z just when Z counterfactually relies on X according to the cold of some you can easily, not necessarily genuine, opinions of your own details that aren’t with the station off X to help you Z. Naturally, to recoup counterfactual reliance anywhere between Suzys put while the smashing we hold fixed BT = 0: had Suzy perhaps not thrown about model in which Billy does not put, this new bottle lack shattered. Likewise getting Billys put.

The fundamental means deployed right here to manage each other preemption and symmetrical overdetermination bears an obvious resemblance in order to Lewiss quasi-dependency substitute for the fresh new late preemption condition. e quasi-hinges on c, yet not, due to the fact you to from inside the a potential world on same laws where intrinsic character of your own processes regarding c to age is the identical but Billy doesnt put, there is the needed counterfactual dependency. ‘Freezing parameters that are not intrinsic toward c-e processes at its real thinking (inside the late preemption circumstances) age.grams. cold BH at the 0 converts roughly an identical key. This new key improvement is that Lewiss solution relates to attractive to brand new realities out-of a completely typical counterfactual (“When the Suzy hadn’t thrown, …”) on a possible business in which certain actual occurrences (elizabeth.g. Billys hit) try not to exists, because the architectural-equations services concerns appealing to the truth away from an excellent counterfactual which have a different variety of antecedent (“Had Suzy not tossed and you can Billys material however perhaps not strike, …”). Hitchcock calls these types of ‘clearly nonforetracking (ENF) counterfactuals. (Also to own symmetrical overdetermination, where i ‘freeze BT in the 0 this time a non-real worth to recoup counterfactual dependence anywhere between Suzys put and shattering.)

5.dos SEF and you can Counterfactuals

Whoever has pursued the latest SEF method to bringing a diagnosis away from ‘genuine causation that is, this new causal relatives anywhere between genuine, sort of occurrences experienced very little to express concerning semantics of the counterfactuals that underpin SEF. Some writers (e.grams. Hitchcock 2001) explicitly and many experts implicitly guess a generally Lewisian method of counterfactuals, therefore, the structural equations was representations away from connections from products regarding counterfactual dependency given that discussed significantly more than whoever facts requirements is actually generally Lewisian.
