The existence of this right, however, must depend upon the causes which may justify its exercise. It is the _ultima ratio_, which presupposes that the proper appeals to all other means of redress have been made in good faith, and which can never be rightfully resorted to unless it be unavoidable. It is not the right of the State, but of the individual, and of all the individuals in the State. It is the right of mankind generally to secure by all means in their power the blessings of liberty and happiness; but when for these purposes any body of men have voluntarily associated themselves under a particular form of government, no portion of them can dissolve the association without acknowledging the correlative right in the remainder to decide whether that dissolution can be permitted consistently with the general happiness. In this view it is a right dependent upon the power to enforce it. Such a right, though it may be admitted to preexist and can not be wholly surrendered, is necessarily subjected to limitations in all free governments, and in compacts of all kinds freely and voluntarily entered into, and in which the interest and welfare of the individual become identified with those of the community of which he is a member. In compacts between individuals, however deeply they may affect their relations, these principles are acknowledged to create a sacred obligation; and in compacts of civil government, involving the liberties and happiness of millions of mankind, the obligation can not be less.
