I: Observations on the Causes of War
Felix, qui potuit rerum cognoscere causas.
Virg.
In the attempt to form an accurate estimate of the moral character of human actions and opinions, it is often of importance to inquire how they have been produced. There is always great reason to doubt the rectitude of that, of which the causes and motives are impure; and if, therefore, it should appear from the observations which follow, that some of the motives to war, and of its causes, are inconsistent with reason or with virtue, I would invite the reader to pursue the inquiry that succeeds them, with suspicion, at least, of the rectitude of our ordinary opinions.
There are some customs which have obtained so generally and so long, that what was originally an effect becomes a cause, and what was a cause becomes an effect, until, by the reciprocal influence of each, the custom is continued by circumstances so multiplied and involved, that it is difficult to detect them in all their ramifications, or to determine those to which it is principally to be referred.
What were once the occasion of wars may be easily supposed—robbery, or the repulsion of robbers, was probably the only motive to hostility, until robbery became refined into ambition, and it was sufficient to produce a war that a chief was not content with the territory of his fathers. But by the gradually increasing complication of society from age to age, and by the multiplication of remote interests and obscure rights, the motives to war have become so numerous and so technical, that ordinary observation often fails to perceive what they are.
