science of his time. It did conflict with the realities. And when the ideal was stated in absolute terms, partly through exuberance and partly for campaign purposes, it was soon forgotten that the theory was originally devised for very special conditions. It became the political gospel, and supplied the stereotypes through which Americans of all parties have looked at politics.
That gospel was fixed by the necessity that in Jefferson's time no one could have conceived public opinions that were not spontaneous and subjective. The democratic tradition is therefore always trying to see a world where people are exclusively concerned with affairs of which the causes and effects all operate within the region they inhabit. Never has democratic theory been able to conceive itself in the context of a wide and unpredictable environment. The mirror is concave. And although democrats recognize that they are in contact with external affairs, they see quite surely that every contact outside that self-contained group is a threat to democracy as originally conceived. That is a wise fear. If democracy is to be spontaneous, the interests of democracy must remain simple, intelligible, and easily managed. Conditions must approximate those of the isolated rural township if the supply of information is to be left to casual experience. The environment must be confined within the range of every man's direct and certain knowledge.
The democrat has understood what an analysis of public opinion seems to demonstrate: that in dealing with an unseen environment decisions "are manifestly settled at haphazard, which clearly they ought not to be."

He feared foreign trade because trade involves foreign connections; he distrusted manufactures because they produced big cities and collected crowds; if he had nevertheless to have manufactures, he wanted protection in the interest of self-sufficiency. When he could not find these conditions in the real world, he went passionately into the
