@K.Rugar, effect without cause weakens a causal argument because it shows that the cause doesn't always produce the effect. It provides evidence that makes it less likely that the cause in question is resulting in the effect. Sure, with your example, someone could have cancer and never have smoked. You're right that it doesn't mean that smoking doesn't cause cancer, but it does make it less likely that it does, because it's showing an instance where the purported cause didn't produce the effect.K.Rugar on November 5, 2020
