From the Declaration of Sentiments at Seneca Falls (1848):
When, in the course of human events, it becomes necessary for one portion of the family of man to assume among the people of the earth a position different from that which they have hitherto occupied, but one to which the laws of nature and of nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes that impel them to such a course.
We hold these truths to be self-evident: that all men and women are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness; that to secure these rights governments are instituted, deriving their just powers from the consent of the governed. Whenever any form of government becomes destructive of these ends, it is the right of those who suffer from it to refuse allegiance to it, and to insist upon the institution of a new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shown that mankind are more disposed to suffer. while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their duty to throw off such government, and to provide new guards for their future security. Such has been the patient sufferance of the women under this government, and such is now the necessity which constrains them to demand the equal station to which they are entitled. The history of mankind is a history of repeated injuries and usurpations on the part of man toward woman, having in direct object the establishment of an absolute tyranny over her. To prove this, let facts be submitted to a candid world.

From Manifesta: Young Women, Feminism and the Future (Jennifer Baumgardner and Amy Richardson, 2000):
When in the course of thirty years of uninterrupted feminism… it becomes evident that a single generation can only go so far, it behooves the next generation to pick up the reins and articulate the plot that will move their cause forward. The first two waves of feminism had clear political goals that involved holding the government accountable to its citizens, the majoriy of whom were getting an unequal deal. In order to have a government that responds to the Third Wave, rather than a society by the few for the few, we need a similar declaration of our sentiments. We need a Manifesta.
