Counterfactual Dependence and Time's Arrow

  title={Counterfactual Dependence and Time's Arrow},
  author={David Lewis},
Today I am typing words on a page. Suppose today were different. Suppose I were typing different words. Then plainly tomorrow would be different also; for instance, different words would appear on the page. Would yesterday also be different? If so, how? Invited to answer, you will perhaps come up with something. But I do not think there is anything you can say about how yesterday would be that will seem clearly and uncontroversially true. The way the future is depends counterfactually on the… 
David Lewis's counterfactual arrow of time
David Lewis (1979) has argued that according to his possible worlds analysis of counterfactuals, "backtracking" counterfactuals of the form "If event A were to happen at tA, then event B would happen
When would Natural Laws have been Broken
It is often held that laws of nature bear a special relation to counterfactual conditionals. In particular, it is suggested that one should retain, under a counterfactual antecedent, all of those
Counterfactuals and temporal direction
A forward counterfactual conditional is one whose consequent is about a later time than any the antecedent is about: ‘If Stevenson had been President in 1953, the Viet Nam war would not have
Counterfactuals and substitution of equivalent antecedents
The aim of this paper is to consider both the specific problem posed by counterexamples of Substitution of Equivalent Antecedents (SEA) and the more general problem of what criteria should be satisfied by good explanations for countereXamples.
Temporal necessity; Hard facts/soft facts
ConclusionIn conclusion, then, the notion of temporal necessity is certainly queer and perhaps a misnomer. It really has little to do with temporality per se and everything to do with counterfactual
Counterfactuals Based on Real Possible Worlds
If Napoleon had won the battle of Waterloo, he would not have died on St. Helena. Under what conditions is this counterfactual true? The Lewis-Stalnaker semantics for conditionals, based upon
Backtracking Counterfactuals Revisited
On my theory, counterfactuals quantify over a suitably restricted set of historical possibilities from some contextually relevant past time and may be related to the fact that emotive factious seem to presuppose knowledge (not just truth) of their complements.
Heim Sequences and Why Most Unqualified ‘Would’-Counterfactuals Are Not True
ABSTRACT The apparent consistency of Sobel sequences (example below) famously motivated David Lewis to defend a variably strict conditional semantics for counterfactuals. If Sophie had gone to the
Quasi-miracles, typicality, and counterfactuals
This paper discusses and criticize the proposals of David Lewis and more recently J. Robert G. Williams which solve the puzzle by taking option (B) and argues that the authors should opt for either (A) or (C).
Counterfactual Contamination 1
Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But the notion of easy possibility in play is relatively undertheorized. One structural idea in the


Theories of Actuality
The problem which I wish to discuss can be introduced by the following presumptuous exercise in imagination. Let us imagine ourselves in the position of Leibniz's God. In His infinite understanding,
The Similarity Approach to Counterfactuals: Some Problems
Although modal logicians have traditionally been interested in counterfactuals, only recently has the application of possible world semantics to the problem of counterfactuals begun to yield formal
Scorekeeping in a language game
It’s not as easy as you might think to say something that will be unacceptable for lack of required presuppositions, and straightway that presupposition springs into existence, making what you said acceptable after all.
