There are quite serious disagreements among claims using counterfactuals. However, when we attempt to analyze such disagreements among counterfactual claims, we also find that there is disagreement among quite different manners of analizing the truth conditions of such counterfactual claims, among which two major theoretical analyses are David Lewis's similarity analysis and Judea Pearl's causality analysis. Meanwhile, Hosokawa (2023) provides a third up-to-date candidate for logical analysis of counterfactuals, i.e., temporality analysis based on hybrid temporal logic. In this article, we see what view emerges if each of similarity analysis and causality analysis is seen from the temporal point of view, and suggest that similarity analysis and causality analysis can be considered as two types of abstraction from temporality analysis. Furthermore, we present prospective contributions by temporality analysis not only to disagreement in counterfactuals but also a wider range of disagreement, i.e., disagreement in projects and policies proposed in the real world.
