"To say that "A causes B" or to say that "B values
precondition A" is to say the same thing. The difference is one of words
only. Instead of saying "A magnet causes iron filings to move toward it,"
you can say "Iron filings value movement toward a magnet."

In "Iron filings value movement toward a magnet." What is B, what is precondition A & what is precondition A
a precondition of?
