Observation in this connection is misled by innumerable side influences, counteractions, and contradictions as yet unsolved. So long as any wreck of humanity is allowed by “the right of love” to reproduce the species, the lines of conclusion in this subject will continue to intersect one another in all directions. _Not until cases arise where the conditions are comparable in every other respect, shall we begin to approach an objective demonstration in the question of children’s decreasing physico-psychical vitality when they are born in unwillingness or indifference, and, on the other hand, of their increasing vitality when they are born in love._ And it is not in the tender years of childhood, but when they have lived their life, that the question can first be finally answered. That the development of children’s inherited dispositions, their childhood’s happiness, and the future tenor of their life are determined to a great extent by their being brought up in a home bright with happiness, by parents who co-operate in sympathetic understanding, this need not be dwelt upon. Everyone knows how children from such homes have received the gift of a faith in life and a feeling of security, a courage and a joy in life which no subsequent sufferings can wholly destroy. They have laid up enough warmth of sunshine to prevent their being frozen through even in the most severe winter. Those, on the other hand, who began with winter, sometimes freeze even under the summer sun. It is no more true with regard to love’s selection than in any other respect that passion is opposed to duty otherwise than in the intermediary stage of development. In the state of innocence there is no division, since no other duty exists but blindly to follow instinct. When development is completed and “the second innocence” attained, duty will be abolished, since it will have become one with instinct.
