Many Americans opposed imperialist actions. Here, the philosopher William James explains his opposition in the light of history.
We used to believe then that we were of a different clay from other nations, that there was something deep in the American heart that answered to our happy birth, free from that hereditary burden which the nations of Europe bear, and which obliges them to grow by preying on their neighbors. Idle dream! pure Fourth of July fancy, scattered in five minutes by the first temptation. In every national soul there lie potentialities of the most barefaced piracy, and our own American soul is no exception to the rule. Angelic impulses and predatory lusts divide our heart exactly as they divide the hearts of other countries. It is good to rid ourselves of cant and humbug, and to know the truth about ourselves. Political virtue does not follow geographical divisions. It follows the eternal division inside of each country between the more animal and the more intellectual kind of men, between the tory and the liberal tendencies, the jingoism and animal instinct that would run things by main force and brute possession, and the critical conscience that believes in educational methods and in rational rules of right.
The country has once for all regurgitated the Declaration of Independence and the Farewell Address, and it won’t swallow again immediately what it is so happy to have vomited up. It has come to a hiatus. It has deliberately pushed itself into the circle of international hatreds, and joined the common pack of wolves. It relishes the attitude. We have thrown off our swaddling clothes, it thinks, and attained our majority. We are objects of fear to other lands.
