"Conceited and self-opinionated people love to teach and give directions. They are not concerned as to the value of their advice. It does not occur to them that they can cause irreparable damage to their neighbor by their misguided advice, which is taken by an inexperienced beginner with irresponsible confidence ... They want to make an impression on the beginner, and subject him morally to themselves. They want human praise. They want to be reputed saints, astute elders, teachers with spiritual insight. They want to nourish their insatiable vanity."
- St. Ignatius Brianchaninov, The Arena
