"For the first voice the infant hears is its mother's, and attempts to form its first babbling to her speech; for at that age it can do nothing but imitate, and takes its first sense experiences, the first furnishings of mind from what it hears its mother say or sees her do; therefore, it is more in the mother's power to shape her child's character
than anyone thinks."
Juan Luis Vives (1453-1540), Spanish humanist
De institutione feminae christianae
(The Education of the Christian Woman), 1524
