If you treat your children at home in the same way you treat your animals in the lab, your wife will scratch your eyes out. My wife ferociously warned me against experimenting on her babies.
Abraham MaslowPeople with intelligence must use their intelligence, people with eyes must use their eyes, people with the capacity to love have the impulse to love and the need to love in order to feel healthy. Capacities clamor to be used, and cease their clamor only when they are used sufficiently. That is to say, capacities are needs, and therefore are intrinsic values as well.
Abraham Maslow
