In short, when Major Barbara says that there are no scoundrels, she is right: there are no absolute scoundrels, though there are impracticable people of whom I shall treat presently. Every practicable man (and woman) is a potential scoundrel and a potential good citizen. What a man is depends on his character; but what he does, and what we think of what he does, depends on his circumstances. The characteristics that ruin a man in one class make him eminent in another. The characters that behave differently in different circumstances behave alike in similar circumstances. Take a common English character like that of Bill Walker. We meet Bill everywhere: on the judicial bench, on the episcopal bench, in the Privy Council, at the War Office and Admiralty, as well as in the Old Bailey dock or in the ranks of casual unskilled labor. And the morality of Bill's characteristics varies with these various circumstances. The faults of the burglar are the qualities of the financier: the manners and habits of a duke would cost a city clerk his situation. In short, though character is independent of circumstances, conduct is not; and our moral judgments of character are not: both are circumstantial. Take any condition of life in which the circumstances are for a mass of men practically alike: felony, the House of Lords, the factory, the stables, the gipsy encampment or where you please! In spite of diversity of character and temperament, the conduct and morals of the individuals in each group are as predicable and as alike in the main as if they were a flock of sheep, morals being mostly only social habits and circumstantial necessities. Strong people know this and count upon it. In nothing have the master-minds of the world been distinguished from the ordinary suburban season-ticket holder more than in their straightforward perception of the fact that mankind is practically a single species, and not a menagerie of gentlemen and bounders, villains and heroes, cowards and daredevils, peers and peasants, grocers and aristocrats, artisans and laborers, washerwomen and duchesses, in which all the grades of income and caste represent distinct animals who must not be introduced to one another or intermarry. Napoleon constructing a galaxy of generals and courtiers, and even of monarchs, out of his collection of social nobodies; Julius Caesar appointing as governor of Egypt the son of a freedman--one who but a short time before would have been legally disqualified for the post even of a private soldier in the Roman army; Louis XI making his barber his privy councillor: all these had in their different ways a firm hold of the scientific fact of human equality, expressed by Barbara in the Christian formula that all men are children of one father. A man who believes that men are naturally divided into upper and lower and middle classes morally is making exactly the same mistake as the man who believes that they are naturally divided in the same way socially.
