equality of all human beings, it is preposterous to wish to exclude half of humanity. Woman has the same right as man to develop her abilities and to employ them freely. She is a human being as well as man and should have the freedom of disposing of her own body and mind and be her own master. The chance of having been born a woman, must not affect her human rights. To exclude woman from equal rights because she has been born a woman and not a man--a fact of which both man and woman are innocent--is as unfair, as to make rights and privileges depend upon religious or political opinion; and it is as irrational as the belief that two persons are innate enemies because, by the chance of birth, they belong to different races or nationalities. Such views are unworthy of a free human being. Progress of humanity consists in removing whatever keeps one human being, one class or one sex in slavery and dependence upon another. ~No difference is justified except those differences established by nature to fulfill its purpose. But no sex will overstep the natural limits, because it would thereby destroy its own purpose in nature.~ [149] Dr. Havelock Ellis.--Man and Woman. 3.--Differences in Physical and Mental Qualities of Man and Woman. One of the chief arguments of the opponents of equal rights is, that woman has a smaller brain than man and is less developed in other respects, and that therefore her lasting inferiority is proven. It is certain that man and woman are two human beings of different sex, that each has different organs adapted to the sexual purpose, and that, owing to the fulfillment of the sexual function, a number of differences in their physiological and psychological conditions exist. These are facts that no one can nor will deny; ~but they do not furnish any cause for social or political inequality between man and woman~. Humanity and society consist of ~both~ sexes; ~both~ are ~indispensable~ to their maintenance and development. Even the greatest man was born by a mother to whom he may owe his best qualities and abilities. By what right, then, can woman be denied equality with man?
