Everywhere the basis of principle is tradition, to such an extent that we even are in danger of making the role of history more important than it is. The other day Professor Ames wrote a learned article to show, among other things, that the common law did not recognize the defence of fraud in actions upon specialties, and the moral might seem to be that the personal character of that defence is due to its equitable origin. But if, as I said, all contracts are formal, the difference is not merely historical, but theoretic, between defects of form which prevent a contract from being made, and mistaken motives which manifestly could not be considered in any system that we should call rational except against one who was privy to those motives. It is not confined to specialties, but is of universal application. I ought to add that I do not suppose that Mr. Ames would disagree with what I suggest.
However, if we consider the law of contract, we find it full of history. The distinctions between debt, covenant, and assumpsit are merely historical. The classification of certain obligations to pay money, imposed by the law irrespective of any bargain as quasi contracts, is merely historical. The doctrine of consideration is merely historical. The effect given to a seal is to be explained by history alone. Consideration is a mere form. Is it a useful form? If so, why should it not be required in all contracts? A seal is a mere form, and is vanishing in the scroll and in enactments that a consideration must be given, seal or no seal. Why should any merely historical distinction be allowed to affect the rights and obligations of business men?
