Concerning the Law of the Weaker.—Whenever any party, for instance, a besieged city, yields to a stronger party, under stipulated conditions, the counter stipulation is that there be a reduction to insignificance, a burning and destruction of the city and thus a great damage inflicted upon the stronger party. Thus arises a sort of equalization principle upon the basis of which a law can be established. The enemy has an advantage to gain by its maintenance.—To this extent there is also a law between slaves and masters, limited only by the extent to which the slave may be useful to his master. The law goes originally only so far as the one party may appear to the other potent, invincible, stable, and the like. To such an extent, then, the weaker has rights, but very limited ones. Hence the famous dictum that each has as much law on his side as his power extends (or more accurately, as his power is believed to extend).
