For example, in saying that Faraday discovered electromagnetic induction ‘in 1831’ we are assigning that event to a certain range of moments. That is, we are specifying on which set of snapshots, in the long sheaf of snapshots of world history, that discovery is to be found. No flow of time is involved when we say when something happened, any more than a ‘flow of distance’ is involved if we say where it happened. But as soon as we say why something happened, we invoke the flow of time.
Common wisdom concepts of time: When—an instance—vs cause and effect—changes involving past events effects on future happenings. Static vs dynamic. Deutsch claims these two perceptions of time contradict; contradict how?
