Generally, those who govern children pardon nothing in them, though they pardon every thing in themselves. This excites in the children a spirit if criticism and malignity; consequently, when they discover any fault in their governors they are delighted, and feel only contempt for them; this posture of self-righteousness actually creates a vindictive spirit in the child who will glory in such a discovery which furnishes an opportunity for recrimination.  – Francois Fenelon,  Education Of A Child
