Aequilibrium indifferentiae
Aequilibrium indifferentiae
The state or condition of exact balance between two actions, the motives being of equal strength. Thomas Aquinas held that in such a condition “actus haberi non potest, nisi removeatur indifferentia.” This is effected by a determination ab intrinseco, or ab extrinseco, which disturbs the equipoise and makes it possible for the agent to act. — J.J.R.
