valued.(141) In savage life the animal nature being supreme, these higher qualities are unknown. In a very elaborate material civilisation the prevailing atmosphere is not favourable either to their production or their appreciation. Their place has usually been in an intermediate stage. On the other hand, there are certain virtues that are the natural product of a cultivated society. Independently of all local and special circumstances, the transition of men from a barbarous or semi-civilised to a highly organised state necessarily brings with it the destruction or abridgment of the legitimate sphere of revenge, by transferring the office of punishment from the wronged person to a passionless tribunal appointed by society;(142) a growing substitution of pacific for warlike occupations, the introduction of refined and intellectual tastes which gradually displace amusements that derive their zest from their barbarity, the rapid multiplication of ties of connection between all classes and nations, and also the strengthening of the imagination by intellectual culture. This last faculty, considered as the power of realisation, forms the chief tie between our moral and intellectual natures. In order to pity suffering we must realise it, and the intensity of our compassion is usually proportioned to the vividness of our realisation.(143) The most frightful catastrophe in South America, an earthquake, a shipwreck, or a battle, will elicit less compassion than the death of a single individual who has been brought prominently before our eyes. To this cause must be chiefly ascribed the extraordinary measure of compassion usually bestowed upon a conspicuous condemned criminal, the affection and enthusiasm that centre upon sovereigns, and many of the glaring inconsistencies of our historical judgments. The recollection of some isolated act of magnanimity displayed by Alexander or Cæsar moves us more than the thought of the 30,000 Thebans whom the Macedonian sold as slaves, of the 2,000 prisoners he crucified at Tyre, of the 1,100,000 men on whose corpses the Roman rose to fame. Wrapt in the pale winding-sheet of general terms the greatest tragedies of history evoke no vivid images in our minds, and it is only by a great effort of genius that an historian can galvanise them into life. The irritation displayed by the captive of St. Helena in his bickerings with his gaoler affects most men more than the thought of the nameless thousands whom his insatiable egotism had hurried to the grave. Such is the frailty of our nature that we are more moved by the tears of some captive princess, by some trifling biographical incident that has floated down the stream of history, than by the sorrows of all the countless multitudes who perished beneath the sword of a Tamerlane, a Bajazet, or a Zenghis Khan.
