In terms of the notion of a working causal channel, Hitchcock defines genuine or token causation from the following terms:
(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 resorts so you’re able to quasi-reliance as shattering of bottle (e) does not counterfactually depend on Suzys place (c), as a consequence of what might keeps happened had she not tossed (viz, Billys stone might have shattered the newest bottles alternatively)
As mentioned, (10) doesnt handle cases of symmetric overdetermination since the whenever Suzy and you can Billy one another throw the stones independently, for each and every put will do for the bottle to-break, and you can each other stones smack the bottles very none put preempts the newest almost every other, once the neither place is found on an energetic route because outlined when you look at the (9). To cope with such as for instance circumstances, Hitchcock weakens (10) by replacing the ‘active route inside the (10) toward idea of a great weakly energetic station (2001: 290). More idea here that there surely is an effective weakly active channel ranging from X and Z simply when Z counterfactually utilizes X in cold of some you can easily, not always genuine, viewpoints of your variables which aren’t to your route regarding X in order to Z. Naturally, to recover counterfactual dependency between Suzys throw while the smashing i hold fixed BT = 0: had Suzy perhaps not thrown throughout the design in which Billy does not put, the latest bottle do not have shattered. Also to own Billys place.
The basic method deployed here to manage one another preemption and shaped overdetermination bears a glaring resemblance so you can Lewiss quasi-dependency substitute for new late preemption state. e quasi-hinges on c, yet not, because you to definitely within the a possible industry for the exact same guidelines the spot where the built-in profile of the process regarding c in order to e is similar Dallas local hookup app near me free however, Billy doesnt put, you have the necessary counterfactual dependency. ‘Cold variables which aren’t built-in toward c-age process within the genuine viewpoints (inside late preemption instances) elizabeth.g. freezing BH during the 0 turns around the same secret. This new key distinction would be the fact Lewiss services concerns attractive to the brand new truth away from a completely normal counterfactual (“If Suzy hadn’t thrown, …”) within a potential business where some genuine situations (e.grams. Billys struck) do not exists, due to the fact architectural-equations solution comes to attractive to the actual situation out-of a beneficial counterfactual having yet another type of antecedent (“Had Suzy maybe not tossed and Billys rock nonetheless perhaps not hit, …”). Hitchcock phone calls these ‘clearly nonforetracking (ENF) counterfactuals. (Also for symmetrical overdetermination, in which we ‘frost BT on 0 this time around a low-real really worth to recuperate counterfactual dependency between Suzys put and also the smashing.)
5.2 SEF and you may Counterfactuals
Anyone who has pursued the new SEF method to getting an analysis regarding ‘actual causation which is, the fresh causal family anywhere between actual, style of occurrences have had little to state about the semantics of your counterfactuals you to underpin SEF. Certain article authors (e.grams. Hitchcock 2001) clearly and some writers implicitly imagine a broadly Lewisian method to counterfactuals, therefore the architectural equations is actually representations out-of relations of affairs on the counterfactual dependency since the described significantly more than whoever facts conditions try generally Lewisian.
