The law of motivation is just as strict as that of physical causality, and hence involves the same irresistible necessity. Consequently wrong may be compassed not only by violence, but also by cunning. If by violence I am able to kill or rob another, or compel him to obey me, I can equally use cunning to accomplish the same ends; that is, I can place false motives before his intellect, by reason of which he must do what otherwise he would not. These false motives are effected by lies. In reality lies are unjustifiable solely in so far as they are instruments of cunning, in other words, of compulsion, by means of motivation.[9] And this is precisely their function, as a rule. For, in the first place, I cannot tell a falsehood without a motive, and this motive will certainly be, with the rarest exceptions, an unjust one; namely, the intention of holding others, over whom I have no power, under my will, that is, of coercing them through the agency of motivation. Also in mere exaggerations and untruthful bombast there is the same purpose at work; for, by employing such language, a man tries to place himself higher in the sight of others than is his due. The binding force of a promise or a compact is contained in the fact that, if it be not observed, it is a deliberate lie, pronounced in the most solemn manner,--a lie, whose intention (that of putting others under moral compulsion) is, in this case, all the clearer, because its motive, the desired performance of something on the other side, is expressly declared. The contemptible part of the fraud is that hypocrisy is used to disarm the victim before he is attacked. The highest point of villainy is reached in =treachery=, which, as we have seen, is a =double= injustice, and is always, regarded with loathing.
