Read the passage from Utopia. Which quotation from the passage best summarizes the central idea?

They detest war as a very brutal thing, and which, to the reproach of human nature, is more practised by men than by any sort of beasts. They, in opposition to the sentiments of almost all other nations, think that there is nothing more inglorious than that glory that is gained by war; and therefore, though they accustom themselves daily to military exercises and the discipline of war, in which not only their men, but their women likewise, are trained up, that, in cases of necessity, they may not be quite useless, yet they do not rashly engage in war, unless it be either to defend themselves or their friends from any unjust aggressors, or, out of good nature or in compassion, assist an oppressed nation in shaking off the yoke of tyranny.
