independent. As interest, therefore, is the immediate sanction of government, the one can have no longer being than the other; and whenever the civil magistrate carries his oppression so far as to render his authority perfectly intolerable, we are no longer bound to submit to it. The cause ceases; the effect must cease also.
So far the conclusion is immediate and direct, concerning the natural obligation which we have to allegiance. As to the moral obligation, we may observe, that the maxim wou'd here be false, that when the cause ceases, the effect must cease also. For there is a principle of human nature, which we have frequently taken notice of, that men are mightily addicted to general rules, and that we often carry our maxims beyond those reasons, which first induc'd us to establish them. Where cases are similar in many circumstances, we are apt to put them on the same footing, without considering, that they differ in the most material circumstances, and that the resemblance is more apparent than real. It may, therefore, be thought, that in the case of allegiance our moral obligation of duty will not cease, even tho' the natural obligation of interest, which is its cause, has ceas'd; and that men may be bound by conscience to submit to a tyrannical government against their own and the public interest. And indeed, to the force of this argument I so far submit, as to acknowledge, that general rules commonly extend beyond the principles, on which they are founded; and that we seldom make any exception to them, unless that exception have the qualities of a general rule, and be founded on very numerous and common instances. Now this I assert to be entirely the present case. When men submit to the authority of others, 'tis to procure themselves some security against the wickedness and injustice of men, who are perpetually carried, by their unruly passions, and by their present and immediate interest, to the violation of all the laws of society. But as this imperfection is inherent in human nature, we know that it must attend men in all their states and conditions; and
