Theodor Mommsen Quote

It is not meant to be denied that in a policy of conquest consistency is a dangerous praise, and that Trajan after his fashion yielded in these enterprises more than was reasonable to the effort after external success, and went beyond the rational; but wrong is done to him when his demeanor in the East is referred to blind lust of conquest. He did what Caesar would have done had he lived. His policy is but the other side of that of Nero's statesmen, and the two are as opposite, as they are equally consistent and equally warranted. Posterity has justified more the policy of conquest than that of concession.
