2. Eugenists are further charged with ignoring or paying too little attention to the influence of the environment in social reform. This charge is sometimes well founded, but it is not an inherent defect in the eugenics program. The eugenist only asks that both factors be taken into account, whereas in the past the factor of heredity has been too often ignored. In the last chapter of this book we make an effort to balance the two sides. 3. Again, it is alleged that eugenics proposes to substitute an aristocracy for a democracy. We do think that those who have superior ability should be given the greatest responsibilities in government. If aristocracy means a government by the people who are best qualified to govern, then eugenics has most to hope from an aristo-democratic system. But admission to office should always be open to anyone who shows the best ability; and the search for such ability must be much more thorough in the future than it has been in the past. 4. Eugenists are charged with hindering social progress by endeavoring to keep woman in the subordinate position of a domestic animal, by opposing the movement for her emancipation, by limiting her activity to child-bearing and refusing to recognize that she is in every way fitted to take an equal part with man in the world's work. This objection we have answered elsewhere, particularly in our discussion of feminism. We recognize the general equality of the two sexes, but demand a differentiation of function which will correspond to biological sex-specialization. We can not yield in our belief that woman's greatest function is motherhood, but recognition of this should increase, not diminish, the strength of her position in the state.
