Such conquests are commonly undertaken by those reckless and daring adventurers who shape and guide each race's territorial growth.

They are sure to come when a masterful people, still in its raw barbarian prime, finds itself face to face with a weaker and wholly alien race which holds a coveted prize in its feeble grasp.
Many good persons seem prone to speak of all wars of conquest as necessarily evil.

This is, of course, a shortsighted view.

In its after effects a conquest may be fraught either with evil or with good for mankind, according to the comparative worth of the conquering and conquered peoples.

It is useless to try to generalize about conquests simply as such in the abstract; each case or set of cases must be judged by itself.
