Abstract
What does it mean if we say that A is the cause of B? The simplest idea of causality is that we mean that B always follows A, but there are two reasons why this cannot be correct. First, a causal relationship need not be perfect: smoking is a cause of lung cancer, but not all smokers get lung cancer. Secondly, even a perfect association is not enough to be regarded as causality: every time the cock crows the sun rises, but this does not of course mean that the cock’s crowing causes the sun to rise.
