consent, they must have in view certain advantages, which they propose to reap from it, and for which they are contented to resign their native liberty. There is, therefore. something mutual engag'd on the part of the magistrate, viz. protection and security; and 'tis only by the hopes he affords of these advantages, that he can ever persuade men to submit to him. But when instead of protection and security, they meet with tyranny and oppression, they are free'd from their promises, (as happens in all conditional contracts) and return to that state of liberty, which preceded the institution of government. Men wou'd never be so foolish as to enter into such engagements as shou'd turn entirely to the advantage of others, without any view of bettering their own condition. Whoever proposes to draw any profit from our submission, must engage himself, either expressly or tacitly. to make us reap some advantage from his authority; nor ought he to expect, that without the performance of his part we will ever continue in obedience.
I repeat it: This conclusion is just, tho' the principles be erroneous; and I flatter myself, that I can establish the same conclusion on more reasonable principles. I shall not take such a compass, in establishing our political duties, as to assert, that men perceive the advantages of government; that they institute government with a view to those advantages; that this institution requires a promise of obedience: which imposes a moral obligation to a certain degree, but being conditional, ceases to be binding, whenever the other contracting party performs not his part of the engagement. I perceive, that a promise itself arises entirely from human conventions, and is invented with a view to a certain interest. I seek, therefore, some such interest more immediately connected with government, and which may be at once the original motive to its institution, and the source of our obedience to it. This interest I find to consist in the security and protection, which we enjoy in political society, and which we can never attain, when perfectly free and
