    “There is evidence that all too many people are approaching parenthood with a dangerous lack of knowledge and skill.

    “The years-heired feature that can
    In curve and voice and eye
    Despise the human span
    Of durance—that is I;
    The eternal thing in man,
    That heeds no call to die.”
    —Thomas Hardy (1840–1928)
