“There is no strong instinctive desire for multitudinous offspring, as such, in the feminine make-up. The reproductive impulses operate indirectly. Nature ensures a pressure of population through passions and instincts that, given sufficient knowledge, intelligence, and freedom on the part of women, can be satisfactorily gratified and tranquillized, if need be, without the production of numerous children. Very slight adjustments in social and economic arrangements will, in a world of clear available knowledge and straightforward practice in these matters, supply sufficient inducement or discouragement to affect the general birth rate or the birth rate of specific types as the directive sense of the community may consider desirable. So long as the majority of human beings are begotten involuntarily in lust and ignorance so long does man remain like any other animal under the moulding pressure of competition for subsistence. Social and political processes change entirely in their character when we recognize the possibility and practicability of this fundamental revolution in human biology.” - H.G.
