Argument: A fetus will become a full-grown person, but only with a right to life
Edward “Ted” Kennedy, U.S. Senator and former presidential candidate, now in favor of legalized abortion, in a letter to a constituent, 8/3/1971 - "While the deep concern of a woman bearing an unwanted child merits consideration and sympathy, it is my personal feeling that the legalization of abortion on demand is not in accordance with the value which our civilization places on human life. Wanted or unwanted, I believe that human life, even at its earliest stages, has certain rights which must be recognized -- the right to be born, the right to love, the right to grow old."
Victoria Woodhull and Tennessee Claflin, Woodhull and Claflin's Weekly (June 20, 1874). - "We are aware that many women attempt to excuse themselves for procuring abortions, upon the ground that it is not murder. But the fact of resort to so weak an argument only shows the more palpably that they fully realize the enormity of the crime. Is it not equally destroying the would-be future oak to crush the sprout before it pushes its head above the sod, as to cut down the sapling, or cut down the tree? Is it not equally to destroy life, to crush it in the very germ, and to take it when the germ has evolved to any given point in its line of development?"
