“O neglectful Nature, wherefore art thou thus partial, becoming to some of thy children a tender and benignant mother, to others a most cruel and ruthless stepmother? I see thy children given into slavery to others without ever receiving any benefit, and in lieu of any reward for the services they have done for them they are repaid by the severest punishments.”

Sermon 62: On the Education of Children, in The Works of Dr. John Tillotson (1772) edited by Thomas Birch, Vol 3, p. 197; this is more commonly quoted as modernized and paraphrased by John Charles Ryle, Anglican Bishop of Liverpool (1880–1900): "To give children good instruction, and a bad example, is but a beckoning to them with the head to show them the way to heaven, while we take them by the hand and lead them in the way to hell."

Reflections on Various Subjects (1665–1678), VII. On Air and Manner
Context: There is an air which belongs to the figure and talents of each individual; we always lose it when we abandon it to assume another. We should try to find out what air is natural to us and never abandon it, but make it as perfect as we can. This is the reason that the majority of children please. It is because they are wrapt up in the air and manner nature has given them, and are ignorant of any other. They are changed and corrupted when they quit infancy, they think they should imitate what they see, and they are not altogether able to imitate it. In this imitation there is always something of falsity and uncertainty. They have nothing settled in their manner and opinions. Instead of being in reality what they want to appear, they seek to appear what they are not.
