A provocative treatise on birth control from a Christian perspective, published in 1922. The author argues against the emerging neo-Malthusian movement, which advocated for birth control as a means of controlling population growth. Sutherland contends that this approach is fundamentally immoral and contrary to Christian principles, and offers an alternative vision for addressing the problem of overpopulation.
