Entirely natural, therefore, is the emphasis which he has placed, whether as President of Princeton or of the United States, upon moral rather than material virtues. This, indeed, has been the essence of his political idealism. Such an emphasis has been for him at once a source of political strength and of weakness. The moralist unquestionably secures wide popular support; but he also wearies his audience, and many a voter has turned from Wilson in the spirit that led the Athenian to vote for the ostracism of Aristides, because he was tired of hearing him called "the Just." Whatever the immediate political effects, the country owes to Wilson a debt, which historians will doubtless acknowledge, for his insistence that morality must go hand in hand with public policy, that as with individuals, so with governments, true greatness is won by service rather than by acquisition, by sacrifice rather than by aggression. Wilson and Treitschke are at opposite poles. During his academic career Wilson seems to have displayed little interest in foreign affairs, and his knowledge of European politics, although sufficient for him to produce an admirable handbook on governments, including foreign as well as our own, was probably not profound. During his first year in the White House, he was typical of the Democratic party, which then approved the political isolation of the United States, abhorred the kind of commercial imperialism summed up in the phrase "dollar diplomacy," and apparently believed that the essence of foreign policy was to keep one's own hands clean. The development of Wilson from this parochial point of view to one which centers his whole being upon a policy of unselfish international service, forms, to a large extent, the main thread of the narrative which follows.
