“The offspring cannot rely on its parents for disinterested guidance. One expects the offspring to be preprogrammed to resist some parental manipulation while being open to other forms. When the parent imposes an arbitrary system of reinforcement (punishment and reward) in order to manipulate the offspring to act against its own best interests, selection will favor offspring that resist such schedules of reinforcement.”

“While parents possess the original key to their offspring's experience, teachers have a spare key. They, too, can open or close the minds and hearts of children.”

“We are now parents. The love for our offspring has opened up fresh fountains of love for each other. Edwin Stanton to his wife.”

“We should try to be the parents of our future rather than the offspring of our past.”

“It looks as if the offspring have eyes so that they can see well (bad, teleological, backward causation), but that's an illusion. The offspring have eyes because their parents' eyes did see well (good, ordinary, forward causation).”

“It still remains unrecognised, that to bring a child into existence without a fair prospect of being able, not only to provide food for its body, but instruction and training for its mind, is a moral crime, both against the unfortunate offspring and against society; and that if the parent does not fulfil this obligation, the State ought to see it fulfilled, at the charge, as far as possible, of the parent.”
