Hmmm. I believe that 'A causes B' *implies* 'A always comes before B',
but not that the first "means the same as" the other. Which of these
did you intend?
The sound of the power coming on always precedes my monitor displaying
pixels. I deny that they have any causative relationship.
As I mentioned to you face-to-face, the book "Causality" by Judea Pearl
presents a graphical notation (based on Bayesian networks) that seems
to allow you to learn many things about what events might be causes of
others once you can describe probabilistic relationships among them.
