Counterfactual dependency: exists between measured value series and measured facts, e.g. pressure. If the pressures had been different, the measured values would have been different. Double counterfactual dependency exists in the case of control mechanisms, where one automatically reacts to the measured value.

Counterfactual dependence/Time/Lewis: counterfactually dependent: assumptions about the future - not counterfactual dependence: assumptions about the past - but: if the present was very different, the past would have had to be different somehow! - Lewis: Thesis: yet no strict asymmetry: - E.g. A is not going to ask B for a favor after a dispute - variant: a) if he asks him, there was no dispute - b) there was definitely a fight - backwards causality/past: Problem: counterfactual conditionals/Co.co. are always vague - e.g. Caesar in the Korean War: would have a) detonated the nuclear bomb - b) used a catapult - solution: special form: if A should ask today, there would not have been a controversy yesterday- normal cases in contrast: here there is the asymmetry.

Alternative/Counterfactual dependence/Causing/Lewis: Analysis 1: Problem: we have to assume a transition period when comparing alternatives. - Because we do not allow jumps - for this transition period the counterfactual dependence does not apply. - Solution: we need an assumption for a certain period of time and a standard solution for vagueness - Analysis 2: comparative similarity of possible worlds - Definition truth/Co.co./Lewis: a Counterfactual Conditional is true if every world that makes the antecedent true also makes the consequent true without leaving the reality for no reason.

Definition counterfactual dependency/Dependent/conD/Lewis: if there is a family of As, A1, A2 and of Cs, C1, C2, ... and if all Counterfactual Conditionals - wA1>wC1, ... wA2>wC2, etc., then the Cs are counterfactually dependent on the As - typical: E.g. measurements and perceptions - E.g. conD, but not causal dependency. E.g. assumed changed laws of gravity with alternative planet movements - because there are no separated events.

Causality/Causal dependency/Separated/Separation/Separatedness/Distinct/Lewis: General: (s) Hume?) causD can only exist between separate entities.) - Solution: Instead, counterfactual dependence: if Socrates had not been conceived, his death would have been impossible.

Cause/Causing/Counterfactual dependence/Lewis/Schwarz: cD: B is happily cD when probability for B without the occurrence of A would have been significantly lower (relative to a time after the actual occurrence of A). - 137 transitivity: Problem: accident causes recovery - fragility: different standards for effect/Cause: Cause: robust: Later throwing also cause, but effect fragile: someone else throws:> different breaking.
