Famous quotes containing the words primitive and/or pit:

    The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.
    Elaine Heffner (20th century)

    I know those little phrases that seem so innocuous and, once you let them in, pollute the whole of speech. Nothing is more real than nothing. They rise up out of the pit and know no rest until they drag you down into its dark.
    Samuel Beckett (1906–1989)
