" For there is indeed danger. There is a danger that is called delusion. It is unable to check itself. It goes on and on: then it is called perdition. But there is a concerned guide, a knowing one, who attracts the attention of the wanderer, who calls out to him that he should take care. That guide is remorse. He is not so quick of foot as the indulgent imagination, which is the servant of desire. He is not so strongly built as the victorious intention. He comes on slowly afterwards. He grieves. But he is a sincere and faithful friend. If that guide’s voice is never heard, then it is just because one is wandering along the way of perdition. "
