Half way through the book I make the argument that Theodore Roosevelt and some of his distinguished contemporaries can be thought of as conservatives. TR never needed to make money for himself (he inherited a fortune) and he exhibited many of the characteristics of a European aristocrat: disdain for the grubbiness of business, a love of the martial virtues, a high sense of honor, and a belief that war is inevitable and glorious. He was a first-rate hunter, believed in the strenuous life, and jumped at the chance to fight in the Spanish-American War. No president has matched him as a vivid and evocative writer: he was an excellent naturalist and a first-rate historian. His histories of the early Republic show the imposition of his conservative judgments on the first decades of American history. He gave high praise to Alexander Hamilton but showed nothing but contempt for Thomas Paine (“that filthy little atheist”). Strong for Washington, he was skeptical about Jefferson.Among TRs friends and contemporaries was Elihu Root, the New York Senator who was dismayed by passage of the 17th Amendment, which transferred the election of senators from the state governments to the entire electorate. Like Shakespeare’s Coriolanus, Root was too proud to grovel to the electors, and resigned his seat rather than run for re-election. The New Republic bade him good riddance, adding that “no man can lead a people who has his back to the future.” Ironically, that’s just what a conservative should do; look backwards to the rich and complex lessons of the past while moving cautiously into the future.Another contemporary was Alfred Thayer Mahan, author of The Influence of Sea Power on History. Mahan also thought that war was inevitable and that the United States needed to be sure that when war came America would fight at an advantage, with the strongest possible force and the most up-to-date weapons. At a Hague peace conference in 1907 he urged his fellow American delegates not to accept the principle of international arbitration, and not to favor the outlawing of poison gas shells. Such commitments would actually put America at an awful disadvantage, he told them. When it came to the point, unscrupulous regimes would use the shells and would reject arbitration, forcing an America that had hamstrung itself through credulity to fight at a disadvantage.I finished the book shortly before the 2008 election and it came out shortly afterwards, when the American conservative movement had suffered a severe check with Obama’s victory and the Republican Party’s defeat. Reviewers and interviewers have all asked me what I make of the current situation, whether Sarah Palin is the future of the GOP, and what will happen next. My answer is: the more you study history, the more you realize how hopeless it is to try to predict the future.I have also often been asked: who are the real conservatives? There is no simple answer to that question. You could take the view that nothing has done more to transform the world in the last 200 years than industrial capitalism, and that to describe its supporters as “conservatives” is an obvious contradiction. But most defenders of capitalism do call themselves conservatives, largely because they see their job as to defend it against various forms of economic collectivism. My job as an historian is to be descriptive rather than prescriptive. If the champions of capitalism do in fact call themselves conservatives, my job is to explain why, rather than try to contradict them.Another question I face nearly every time I write and speak on this topic is: are you a conservative? The answer is a mixture of yes and no. On the one hand I grew up in Britain during its long flirtation with socialism and always believed in the essential rightness of the National Health Service. That makes me a lefty by American standards. On the other hand I became a passionate anti-Communist after reading the work of Solzhenitsyn in the 1970s, and I believe equally strongly in the essential rightness of free-market capitalism, which has done more than anything else to enrich the world and liberate the masses from misery and poverty. That makes me a conservative, at least of a kind. So does my skepticism about the perfectibility of human nature. I agree with many of the people I wrote about that we are all sinners and that we need to live with institutions that recognize this reality and impose necessary constraints on us.
