One answer is, that they have the motive of justice. It would be unjust to compel the minority to contribute, by taxation, to the support of any laws which they did not approve.
Another answer is, that if the stronger party wish to use their power only for purposes of justice, they have no occasion to fear the veto of the weaker party; for the latter have as strong motives for the maintenance of just government, as have the former.
Another answer is, that if the stronger party use their power unjustly, they will hold it by an uncertain tenure, especially in a community where knowledge is diffused; for knowledge will enable the weaker party to make itself in time the stronger party. It also enables the weaker party, even while it remains the weaker party, perpetually to annoy, alarm, and injure their oppressors. Unjust power, or rather power that is grossly unjust, and that is known to be so by the minority, can be sustained only at the expense of standing armies, and all the other machinery of force; for the oppressed party are always ready to risk their lives for purposes of vengeance, and the acquisition of their rights, whenever there is any tolerable chance of success. Peace, safety, and quiet for all, can be enjoyed only under laws that obtain the consent of all. Hence tyrants frequently yield to the demands of justice from those weaker than themselves, as a means of buying peace and safety.
Still another answer is, that those who are in the majority on one law, will be in the minority on another. All, therefore, need the benefit of the veto, at some time or other, to protect themselves from injustice.
That the limits, within which legislation would, by this process, be confined, would be exceedingly narrow, in comparison with those it at present occupies, there can be no doubt. All monopolies, all special privileges, all sumptuary laws, all restraints upon any traffic, bargain, or contract, that was naturally lawful, [1] all restraints upon men's natural rights, the whole catalogue of mala prohibita, and all taxation to which the taxed parties had not individually, severally, and freely consented, would be at an end; because all such legislation implies a violation of the rights of a greater or less minority. This minority would disregard, trample upon, or resist, the execution of such legislation, and then throw themselves upon a jury of the whole people for justification and protection. In this way all legislation would be nullified, except the legislation of that general nature which impartially protected the rights, and subserved the interests, of all. The only legislation that could be sustained, would probably be such as tended directly to the maintenance of justice and liberty; such, for example, as should contribute to the enforcement of contracts, the protection of property, and the prevention and punishment of acts intrinsically criminal. In short, government in practice would be brought to the necessity of a strict adherence to natural law, and natural justice, instead of being, as it now is, a great battle, in which avarice and ambition are constantly fighting for and obtaining advantages over the natural rights of mankind.

APPENDIX
TAXATION
It was a principle of the Common Law, as it is of the law of nature, and of common sense, that no man can be taxed without his personal consent. The Common Law knew nothing of that system, which now prevails in England, of assuming a man's own consent to be taxed, because some pretended representative, whom he never authorized to act for him, has taken it upon himself to consent that he may be taxed. That is one of the many frauds on the Common Law, and the English constitution, which have been introduced since Magna Carta. Having finally established itself in England, it has been stupidly and servilely copied and submitted to in the United States.
If the trial by jury were reestablished, the Common Law principle of taxation would be reestablished with it; for it is not to be supposed that juries would enforce a tax upon an individual which he had never agreed to pay. Taxation without consent is as plainly robbery, when enforcers against one man, as when enforced against millions; and it is not to be imagined that juries could be blind to so self-evident a principle. Taking a man's money without his consent, is also as much robbery, when it is done by millions of men, acting in concert, and calling themselves a government, as when it is done by a single individual, acting on his own responsibility, and calling himself a highwayman. Neither the numbers engaged in the act, nor the different characters they assume as a cover for the act, alter the nature of the act itself.
