Which sentence in this excerpt from Elizabeth Cady Stanton's speech "Solitude of Self" conveys that it is important for women to be literate?Fourthly, it is only the incidental relations of life, such as mother, wife, sister, daughter, that may involve some special duties and training. In the usual discussion in regard to woman's sphere, such as men as Herbert Spencer, Frederic Harrison, and Grant Allen uniformly subordinate her rights and duties as an individual, as a citizen, as a woman, to the necessities of these incidental relations, some of which a large class of woman may never assume. In discussing the sphere of man we do not decide his rights as an individual, as a citizen, as a man by his duties as a father, a husband, a brother, or a son, relations some of which he may never fill. Moreover he would be better fitted for these very relations and whatever special work he might choose to do to earn his bread by the complete development of all his faculties as an individual.
Just so with woman. The education that will fit her to discharge the duties in the largest sphere of human usefulness will best fit her for whatever special work she may be compelled to do.
The isolation of every human soul and the necessity of self-dependence must give each individual the right, to choose his own surroundings.
