Hence, again, he deduces the need for some sort of army, so that the goods of the citizens may be secured against the invader, for without this security there would be no stimulus to trade. Bridges must be built, and fords kept in repair. Since, therefore, the State is obliged to incur expenses in order to attain these objects, the State has the right, and indeed the duty, to order it so that the community shall pay for the benefits which it is to receive. Hence follows taxation.
But he sees at once that this power of demanding forced contributions from wealthy members of society needs safeguarding against abuse. Thus he is careful to insist that taxation can be valid only when it is levied by public authority, else it becomes sheer brigandage. No less is it to be reprobated when ordered indeed by public authority, but not used for public benefit. Thus, should it happen that a prince or other ruler of a State extorted money from his subjects on pretence of keeping the roads in good order, or similar works for the advantage of the community, and yet neglected to put the contributions of his people to this use, he would be defrauding the public, and guilty of treason against his country. So, too, to lay heavier burdens on his subjects than they could bear, or to graduate the scale in such a fashion as to weigh more heavily on one class than another, would be, in the ruler, an aggravated form of theft. Taxation must therefore be decreed by public authority, and be arranged according to some reasonable measure, and rest on the motive of benefiting the social organisation.
The citizens therefore who are elected to settle the incidence of taxation must be careful to take account of the income of each man, and so manage that on no one should the burden be too oppressive. He suggests himself the percentage of one pound per hundred. Nor, again, must there be any deliberate attempt to penalise political opponents, or to make use of taxation in order to avenge class-oppression. Were this to be done, the citizens so acting would be bound to make restitution to the persons whom they had thus injured.
Then St. Antonino takes the case of those who make a false declaration of their income. These, too, he convicts of injustice, and requires of them that they also should make restitution, but to the State. An exception to this, however, he allows. For if it happens to be the custom for each to make a declaration of income which is obviously below the real amount, then simply because all do it and all are known to do it, there is no obligation for the individual to act differently from his neighbours. It is not injustice, for the law evidently recognises the practice. And were he, on the other hand, to announce his full yearly wage of earnings, he would allow himself to be taxed beyond the proper measure of value. But to refuse to pay, or to elude by some subterfuge the just contribution which a man owes of his wealth to the easing of the public burdens, is in the eyes of the Archbishop a crime against the State. It would be an act of injustice, of theft, all the more heinous in that, as he declares with a flash of the energy of Rousseau, the "common good is something almost divine."
We have dwelt rather at length on the schemes of this one economist, and may seem, therefore, to have overlooked the writings of others equally full of interest. But the reason has been because this Florentine moralist does stand so perfectly for a whole school. He has read omnivorously, and has but selected most of his thoughts. He compares himself, indeed, in one passage of these volumes, to the laborious ant, "that tiny insect which wanders here and there, and gathers together what it thinks to be of use to its community." He represents a whole school, and represents it at its best, for there is no extreme dogmatism in him, no arguing from grounds that are purely arbitrary, or from a priori principles. It is his knowledge of the people among whom he had laboured so long which fits him to speak of the real sufferings of the poor. But experience requires for its being effectually put to the best advantage, that it should be wielded by one whose judgment is sober and careful. Now, St. Antonino was known in his own day as Antonino the Counsellor; and his justly-balanced decision, his delicately-poised advice, the straightness of his insight, are noticeable in the masterly way in which he sums up all the best that earlier and contemporary writers had devised in the domain of social economics.
There is, just at the close of the period with which this book deals, a rising school of reformers who can be grouped round More's Utopia. Some foreshadowed him, and others continued his speculations. Men like Harrington in his Oceana, and Milton in his Areopagitica, really belong to the same band; but life for them had changed very greatly, and already become something far more complex than the earlier writers had had to consider. There seemed no possibility of reforming it by the simple justice which St. Antonino and his fellows judged to be sufficient to set things back again as they had been in the Golden Age. The new writers are rather political than social. For them, as for the Greeks, it is the constitution which must be repaired. Whereas the mediaeval socialists thought, as St. Thomas indeed never wearied of repeating, that unrest and discontent would continue under any form of government whatever. The more each city changed its constitution, the more it remained the same. Florence, whether under a republic or a despotism, was equally happy and equally sad. For it was the spirit of government alone which, in the eyes of the scholastic social writers, made the State what it happened to be.
In this the modern sociologist of to-day finds himself more akin with the mediaeval thinkers than with the idealists of the parliamentary era in England, or of the Revolution in France. These fixed their hopes on definite organisations of government, and on the exact balance of executive and legislative powers. But for Scotus, and Wycliff, and St. Antonino, the cause of the evil is far deeper and more personal. Not in any form of the constitution, nor in any division of ruling authority, nor in its union under a firm despot, nor in the divine right of kings, or nobles, or people, was security to be found, or the well-ordering of the nation. But peace and rest from faction could be achieved with certainty only on the conditions of strict justice between man and man, on the observance of God's commandments.
