When, in the course of human events, it becomes necessary for one people to dissolve the political bonds which have connected them with another, and to assume among the powers of the earth, the separate and equal station 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 which impel them to the separation.

President Lincoln, perhaps above all others, was instrumental in making clear that the second sentence of the Declaration was “a moral standard for which the United States should strive,” as Wikipedia puts it.
