What is natural to both sexes can only be discovered by allowing both sexes to develop and use their faculties. (Moulin, 1869). Mill wrote The Subjection of Women which is based on the current law of force and not modern reason. Since no other opinions or viewpoints were taught, the subjugation of the "weaker female" to the "stronger Alpha male" is based on an unproven theory. Mill hoped to pave the way for a new system of equality based on theory, as no practice of gender equality had yet been implemented.
