[ULPIANUS libro undecimo ad edictum. ] §4.2.1.prAit praetor: 'Quod metus causa gestum erit, ratum non habebo'. olim ita edicebatur 'quod ui metusue causa': uis enim fiebat mentio propter necessitatem impositam contrariam uoluntati: metus instantis uel futuri periculi causa mentis trepidatio.
[ULPIAN, On the Edict, book 11] The praetor says: "I will not hold valid what has been done because of fear." Formerly, it was edicted thus: "what because of force or fear"; for mention was made of force because of a necessity imposed contrary to the will, whereas fear is a trepidation of the mind because of an imminent or future danger.
sed postea detracta est uis mentio ideo, quia quodcumque ui atroci fit, id metu quoque fieri uidetur.
But later, the mention of force was removed for the reason that whatever is done by atrocious force seems to be done by fear as well.
