“It would be one of the greatest triumphs of humanity, one of the most tangible liberations from the constraints of nature to which mankind is subject, if we could succeed in raising the responsible act of procreating children to the level of a deliberate and intentional activity and in freeing it from its entanglement with the necessary satisfaction of a natural need.”
—Sigmund Freud (1856–1939)
“The distractions, the exhaustions, the savage noises, the demands of town life, are, for me, mortal enemies to thought, to sleep, and to study; its extremes of squalor and of splendor do not stimulate, but sadden me; certain phases of its society I profoundly value, but would sacrifice them to the heaven of country quiet, if I had to choose between.”
—Elizabeth Stuart Phelps (1844–1911)
