 And yet, if the bomb explodes it was caused by the Geiger counter arrangement. Causation thus does not involve determination or necessity. Since the radioactive decay was not sufficient for this effect, the case tells against viewing causes as sufficient conditions. There need be no general connection between cause and effect. This challenge to the Humean account would turn out to be very influential – it helped push philosophers towards the development of probabilistic accounts of causation to account for the above type of case.
