H. M. Blamires describes C.S. Lewis as someone who knew both how to 'nourish a pupil with encouragement and how to press criticism when it was needed without causing resentment'... Luke Rigby further describes Lewis; 'What stands out in my memory is the warmth of the man. He was always welcoming and showed interest and concern. The startling contrast between his achievement and my mediocre promise did not open a gulf; he was a true master, the true teacher. He shared his appreciation and enthusiasm and thereby instilled confidence.' (Quoted in Edward Sellner, Mentoring: The Ministry of Spiritual Kinship, Ave Maria Press, 1990, pg. 40
