The world of white civilization is intellectually rich because it has amassed a rich fund of general ideas, and has organized these into specialized bodies of knowledge, and has also developed a special technique for the presentation of this knowledge and standpoint to the young members of society, and for localizing their attention in special fields of interest. When for any reason a class of society is excluded from this process, as women have been historically, it must necessarily remain ignorant. But, while no one would make any question that women confined as these in New Ireland and China, as shown above, must have an intelligence as restricted as their mode of life, we are apt to lose sight altogether of the fact that chivalry and chaperonage and modern convention are the persistence of the old race habit of contempt for women, and of their intellectual sequestration. Men and women still form two distinct classes and are not in free communication with each other. Not only are women unable and unwilling to be communicated with directly, unconventionally, and truly on many subjects, but men are unwilling to talk to them. I do not have in mind situations involving questions of propriety or delicacy alone, but a certain habit of restraint, originating doubtless in matters relating to sex, extends to all intercourse with women, with the result that they are not really admitted to the intellectual world of men; and there is not only a reluctance on the part of men to admit them, but a reluctance—or, rather, a real inability—on their part to enter. Modesty with reference to personal habits has become so ingrained and habitual, and to do anything freely is so foreign to woman, that even free thought is almost of the nature of an immodesty in her.
