There are persons of a very practical turn of mind, who, on hearing of any new scientific work, ask what political party the author aims to please, and who think that every poem should contain a moral lesson. These people think that propagandism is the only object that a writer has in view. The idea of an art or science aspiring only after the true and beautiful, without regard either to policy or politics, is something quite strange to them. Between such persons and ourselves misapprehensions are inevitable. "There are people," said a Greek philosopher, "who take with their left hand what is offered to them with their right." A number of letters, dictated by a really honest sentiment, which have been sent me, may be summed up in the question, "What is the matter with you? What end are you aiming at?" Why, I write for precisely the same reason that all historical writers do. If I could have several lives, I would devote one to writing a life of Alexander, another to a history of Athens, and a third to either a history of the French Revolution or the monkish order of St. Francis. In writing these works I would be actuated by a desire to find the truth, and would endeavor to make the mighty events of the past known with the greatest possible exactness, and related in a manner worthy of them. Far from me be the thought of shocking the religious faith of any person! Such works should be prepared with as much supreme indifference as if they were written in another planet. Every concession to the scruples of an inferior order, is a derogation from the dignity and culture of art and truth. It can at once be seen that the absence of proselytism is the leading feature of works composed in such a spirit.
