The laws of war, that restrain the exercise of national rapine and murder, are founded on two principles of substantial interest: the knowledge of the permanent benefits which may be obtained by a moderate use of conquest, and a just apprehension lest the desolation which we inflict on the enemy's country may be retaliated on our own. But these considerations of hope and fear are almost unknown in the pastoral state of nations.
Edward GibbonThe ancients were destitute of many of the conveniences of life which have been invented or improved by the progress of industry; and the plenty of glass and linen has diffused more real comforts among the modern nations of Europe than the senators of Rome could derive from all the refinements of pompous or sensual luxury.
