Begin therefore betimes nicely to observe your son's temper; and that, when he is under least restraint, in his play, and as he thinks out of your sight. See what are his predominate passions and prevailing inclinations; whether he be fierce or mild, bold or bashful, compassionate or cruel open or reserv'd, &c. For as these are different in him, so are your methods to be different, and your authority must hence take measures to apply itself different ways to him.
