Modern accounts of causation involve either processes or counterfactuals [Baron/Miller]
26. Natural Theory / C. Causation / 4. Naturalised causation
The main process theory of causation says it is transference of mass, energy, momentum or charge [Baron/Miller]
If causes are processes, what is causation by omission? (Distinguish legal from scientific causes?) [Baron/Miller]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation

The error theory of time's passage says it is either a misdescription or a false inference [Baron/Miller]

It is meaningless to measure the rate of time using time itself, and without a rate there is no flow [Baron/Miller]

The C-series rejects A and B, and just sees times as order by betweenness, without direction [Baron/Miller]
