When, long after the spirit of the constitution has departed, moderation is at length so far lost by those in power, that even the semblance of freedom is removed, and the forms themselves of the constitution discontinued, and so far from their petitions and remonstrances being regarded, the agents who bear them are thrown into dungeons, and mercenary armies sent forth to force a new government upon them at the point of the bayonet.
When, in consequence of such acts of malfeasance and abduction on the part of the government, anarchy prevails and civil society is dissolved into its original elements, in such a crisis, the first law of nature, the right of self preservation, the inherent and inalienable right of the people to appeal to first principles, and take their political affairs into their own hands in extreme cases, enjoins it as a right towards themselves and a sacred obligation to their posterity to abolish such government, and create another in its stead, calculated to rescue them from impending dangers, and to secure their welfare and happiness.
