of the judge who gives a decision, nor does the value of a rare painting rest chiefly in the intensity of desire of the few rich connoisseurs who compete for it. Back of the judge, giving _validity_ to his decision, stands the will of the group; back of the rich connoisseurs stand the legal and other social values concerned with the distribution of wealth, by virtue of which they are able to make their wants felt in the market. Both judge and connoisseur are focal points, through which stream the social forces affecting the values in question. Both are important. But the emotions and ideas of neither exhaust the psychological causation involved in the values. This is very much more apparent when we consider the values that arise in the great speculative markets, say in the wheat pit, or the stock exchange. Those who buy and sell are primarily interpreters, students, of impersonal, social forces, seeking to adjust themselves to them, to forecast them, in such a way as to derive profit from them. Their choices and decisions are also factors. Indeed, it is possible to view the matter in such a way as to make their decisions the whole story. In the same way, it is possible to make the mind of the judge the final explanation of the legal value. But the speculators themselves are under no such illusion. They know very well that if they run counter to the facts they will lose money. And the judge knows very well that the range of arbitrary choice which he can exercise without impeachment, or at least without reversal by a higher court, is very limited. Nor is even a Supreme Court of the United States free to do its arbitrary will. Just because it is so conspicuous, and because its doings are so important, it has manifested more respect for judicial tradition, and more responsiveness to the tides of public sentiment, than any other court in the Federal Judiciary.[35]
