In all cases in which I have a right of compulsion, a complete right to use _violence_ against another, I may, according to the circumstances, just as well oppose the violence of the other with _craft_ without doing any wrong, and accordingly I have an actual _right to lie precisely so far as I have a right of compulsion_. Therefore a man acts with perfect right who assures a highway robber who is searching him that he has nothing more upon him; or, if a burglar has broken into his house by night, induces him by a lie to enter a cellar and then locks him in. A man who has been captured and carried off by robbers, for example by pirates, has the right to kill them not only by violence but also by craft, in order to regain his freedom. Thus, also, a promise is certainly not binding when it has been extorted by direct bodily violence, because he who suffers such compulsion may with full right free himself by killing, and, _a fortiori_, by deceiving his oppressor. Whoever cannot recover through force the property which has been stolen from him, commits no wrong if he can accomplish it through craft. Indeed, if some one plays with me for money he has stolen from me, I have the right to use false dice against him, because all that I win from him already belongs to me. Whoever would deny this must still more deny the justifiableness of stratagem in war, which is just an acted lie, and is a proof of the saying of Queen Christina of Sweden, “The words of men are to be esteemed as nothing; scarcely are their deeds to be trusted.” So sharply does the limit of right border upon that of wrong. For the rest, I regard it as superfluous to show that all this completely agrees with what was said above about the unlawfulness of the lie and of violence. It may also serve to explain the peculiar theory of the lie told under pressure.(75)
