Character is Samuel Smiles's companion to Self-Help, and where that earlier book studied energy and perseverance, this one studies the moral fibre behind them. Smiles opens by setting character above genius. Genius commands admiration, but character secures respect; the one is the intellect of society, the other its conscience. Most people will never have the chance to be great, but each can do his duty honestly in the sphere where he is placed, and that plain faithfulness, Smiles insists, is the highest ideal of life.
The book then traces where character comes from, beginning with the home. Smiles calls home the first and most important school of character, the place where habits are formed and the heart is opened for good or for evil. He gives great weight to early example and especially to mothers, arguing that the smallest influences of childhood endure through life and that the character of a nation is rooted in its nurseries.
From the home the account widens to companionship and work. Because people imitate those around them almost unconsciously, the friends and examples a person keeps shape him as surely as his upbringing did. Work then becomes one of the best educators of practical character: it disciplines attention, self-control, and perseverance, while idleness, not labour, eats the heart out of individuals and nations alike.
Smiles devotes central chapters to courage and self-control. The courage he praises is moral rather than physical, the nerve to be just, honest, and truthful and to resist temptation even when it costs. Self-control he treats as courage in another form and as the root of all the virtues, since a person who gives the reins to impulse forfeits his moral freedom and becomes the slave of his strongest desire. Habit, rightly trained, is the steady support of this self-mastery.
The closing chapters carry character into the world. Cloistered, untested virtue counts for little; character must be able to bear the wear and tear of actual life. It is the discipline of experience, including the discipline of suffering, that gives character the touch of truth no precept or book can supply. Across the whole work Smiles returns to one claim: that the strength of a people lies not in its wealth or arms but in the quality of its cultivated, dutiful citizens.
