"I have, alas, only one illusion left, and that is the Archbishop of Canterbury"

Sydney Smith's quote is a reflection on the power of faith and the significance of faith in his life. He is revealing his sadness at having only one staying source of hope and comfort in his life, which is the Archbishop of Canterbury. This suggests that Smith had a strong belief in the power of the Church and its teachings, and that he aimed to the Archbishop for assistance and solace. He may have been feeling a sense of solitude and anguish, and the Archbishop was the something that could bring him convenience. Smith's quote is a reminder of the importance of faith and religion in our lives, and how it can provide us with hope and strength in difficult times. It likewise serves as a pointer of the power of the Church and its mentors, and how it can offer us with guidance and assistance.
