If our benevolent feelings are thus the slaves of our imaginations, if an act of realisation is a necessary antecedent and condition of compassion, it is obvious that any influence that augments the range and power of this realising faculty is favourable to the amiable virtues, and it is equally evident that education has in the highest degree this effect. To an uneducated man all classes, nations, modes of thought and existence foreign to his own are unrealised, while every increase of knowledge brings with it an increase of insight, and therefore of sympathy. But the addition to his knowledge is the smallest part of this change. The realising faculty is itself intensified. Every book he reads, every intellectual exercise in which he engages, accustoms him to rise above the objects immediately present to his senses, to extend his realisations into new spheres, and reproduce in his imagination the thoughts, feelings, and characters of others, with a vividness inconceivable to the savage. Hence, in a great degree, the tact with which a refined mind learns to discriminate and adapt itself to the most delicate shades of feeling, and hence too the sensitive humanity with which, in proportion to their civilisation, men realise and recoil from cruelty. We have here, however, an important distinction to draw. Under the name of cruelty are comprised two kinds of vice, altogether different in their causes and in most of their consequences. There is the cruelty which springs from callousness and brutality, and there is the cruelty of vindictiveness. The first belongs chiefly to hard, dull, and somewhat lethargic characters, it appears most frequently in strong and conquering nations and in temperate climates, and it is due in a very great degree to defective realisation. The second is rather a feminine attribute, it is usually displayed in oppressed and suffering communities, in passionate natures, and in hot climates. Great vindictiveness is often united with great tenderness, and great callousness with great magnanimity, but a vindictive nature is rarely magnanimous, and a brutal nature is still more rarely tender. The ancient Romans exhibited a remarkable combination of great callousness and great magnanimity, while by a curious contrast the modern Italian character verges manifestly towards the opposite combination. Both forms of cruelty are, if I mistake not, diminished with advancing civilisation, but by different causes and in different degrees. Callous cruelty disappears before the sensitiveness of a cultivated imagination. Vindictive cruelty is diminished by the substitution of a penal system for private revenge.
