It seems, then, that a system of just and useful laws may be constructed nearly, if not wholly, on the principle of the right of self-defence, or the security for person, liberty, and property. There are exceptions, such, for instance, as in the case of children, idiots, and insane persons. These common-sense dictates for a general principle can only hold good where the general conditions are complied with. There are also mixed cases, partaking of civil and moral justice. Is a man bound to support his children? Not in strict political right; but he may be compelled to forego all the benefits of civil society, if he does not fulfil an engagement which, according to the feelings and principles of that society, he has undertaken. So in respect to marriage. It is a voluntary contract, and the violation of it is punishable on the same plea of sympathy and custom. Government is not necessarily founded on common consent, but on the right which society has to defend itself against all aggression. But am I bound to pay or support the government for defending the society against any violence or injustice? No: but then they may withdraw the protection of the law from me if I refuse, and it is on this ground that the contributions of each individual to the maintenance of the state are demanded. Laws are, or ought to be, founded on the supposed infraction of individual rights. If these rights, and the best means of maintaining them, are always clear, and there could be no injustice or abuse of power on the part of the government, every government might be its own lawgiver: but as neither of these is the case, it is necessary to recur to the general voice for settling the boundaries of right and wrong, and even more for preventing the government, under pretence of the general peace and safety, from subjecting the whole liberties, rights, and resources of the community to its own advantage and sole will. 1828.
