Some random thoughts about causation, in no particular order:

You can observe correlations, but you can never observe a cause.

Correlation is not causation, but then again causation doesn't exist outside of formal logical systems.

Formal logical systems can be mapped onto the phenomena our senses reveal, but the mapping is always approximate.

Causation is a weak concept in physical science. Far weaker than causation in formal systems.

Causation is not time symmetric.

Since causation is not time symmetric, it is incompatible with classical physics.

Causation says two things:
1) The cause (state A) must exist in order for the effect (state B) can exist.
2) The effect (state B) must follow whenever the cause (state A) exists.

Observed phenomena almost never follow rules of causation of formal logical systems.

Observed phenomena follow a probabilistic pattern of "causation." A cause can have many effects and effects can have many causes. An effect will follow its cause most of the time but not always.

Rosen's relational biology describes anticipatory systems, characterized by feedback loops where effects may appear to precede causes in complex interdependent ways.
