The chief consequence of this growing tendency in modern juristic thinking is seen in the change in attitude towards contract. The fundamental question of relation, of association, is—Can you make one idea grow where two grew before? _This_ is the law of fruitful increase. The gradual progress away from contract in legal theory is just the gradual recognition of this principle. You can have a contractual relation between two wills or you can have those two wills uniting to form one will. Contract never creates one will. It is the latter process which is shown in the development of corporation law.[51] The laws regulating partnership are based on contractual relations between the individual members. The laws regulating corporations are based on the theory that a corporation is something quite different from the individuals who constitute it or the sum of those individuals, that a new entity has been created. I am writing at this moment (February, 1918) in a room with the thermometer at 42, but the law would not uphold me in going and getting my share, as a stock holder, of the coal now in the New York, New Haven and Hartford sheds! But to many the personality of the corporation is a fiction: they do not consider the corporation a self-created entity but a state-created entity. To others, following Gierke, the corporation is merely a state-_recognized_ entity, it has the inherent power to create itself. The increasing acceptance of this latter theory has made it possible to hold liable groups which have not been legally incorporated but which exercise powers analogous to those of corporations. This has been the principle of some of the English decisions making trade-unions responsible, as notably in the Taff-Vale case. The paradox of contract is that while it seems to be based on relation, it is in reality based on the individual. Contract is a particularist conception. Mr. Pound speaks of the significance of the “parallel movement away from liberty of contract and yet at the same time towards the full recognition of association.” It is the legal theory of association based on our growing understanding of group psychology which will finally banish contract. When Duguit, the eminent French jurist, tells us that contract is diminishing, it is because he sees a time when all juridical manifestations will come from unilateral acts.[52] We see contract diminishing because we believe in a different mode of association: as fast as association becomes a “community” relation, as fast as individuals are recognized as community-units, just so fast does contract fade away. Jellinek points out that legal theory is coming to recognize that violation of community is quite different from the violation of contract.
