discoverers and colonizers and pioneers and traders and entrepreneurs and captains of industry. Until the world became crowded, it served well to eliminate friction and to promote the widest discovery and utilization of the natural resources of human existence. Looking back at the history of this conception, which has governed theories of the end of law for more than two hundred years, we may note that it has been put to three uses. It has been used as a means of clearing away the restraints upon free economic activity which accumulated during the Middle Ages as incidents of the system of relational duties and as expressions of the idea of holding men to their place in a static social order. This negative side played an important part in the English legislative reform movement in the last century. The English utilitarians insisted upon removal of all restrictions upon individual free action beyond those necessary for securing like freedom on the part of others. This, they said, was the end of legislation. Again it has been used as a constructive idea, as in the seventeenth and eighteenth centuries, when a commercial law which gave effect to what men did as they willed it, which looked at intention and not at form, which interpreted the general security in terms of the security of transactions and sought to effectuate the will of individuals to bring about legal results, was developed out of Roman law and the custom of merchants through juristic theories of natural law. Finally it was used as a stabilizing idea, as in the latter part of the nineteenth century, when men proved that law was an evil, even if a necessary evil, that there should be as little law made as possible, since all law involved restraint upon free exertion of the will, and hence that jurist and legislator should be content to leave things legal as they are and allow the individual "to work out in freedom his own happiness or misery" on that basis.
