And this kind of Dominion, or Soveraignty, differeth from Soveraignty by Institution, onely in this, That men who choose their Soveraign, do it for fear of one another, and not of him whom they Institute: But in this case, they subject themselves, to him they are afraid of. In both cases they do it for fear: which is to be noted by them, that hold all such Covenants, as proceed from fear of death, or violence, voyd: which if it were true, no man, in any kind of Common-wealth, could be obliged to Obedience. It is true, that in a Common-wealth once Instituted, or acquired, Promises proceeding from fear of death, or violence, are no Covenants, nor obliging, when the thing promised is contrary to the Lawes; But the reason is not, because it was made upon fear, but because he that promiseth, hath no right in the thing promised. Also, when he may lawfully performe, and doth not, it is not the Invalidity of the Covenant, that absolveth him, but the Sentence of the Soveraign. Otherwise, whensoever a man lawfully promiseth, he unlawfully breaketh: But when the Soveraign, who is the Actor, acquitteth him, then he is acquitted by him that exorted the promise, as by the Author of such absolution.
