Action includes tendency to motion, not just actual motion

Evidence

Under the term action, besides motion, a tendency, though so it be without actual motion, seems to be included. Held back by strings, a magnet and a bar of iron, suspended at a certain distance from each other, remain both of them without motion: cut the strings of either of them, it moves till it comes in contact with the other; but for the state of mutual action which preceded the cutting of the strings no such motion would have taken place. — Jeremy Bentham, The Panopticon Writings, 510

  • XREF: connects to: Freedom depends on the capacity of motion which requires space; Motion resists ontological derivation and must be accepted as a contingent fact; Motion alters a quality’s mode of being rather than its essence (+2 more)
