A quote
I hope some day to be wise, but meanwhile I am not wise. For if I possessed that Good, I should now be free from this Evil. Some day I shall be wise; from this very fact you may understand that I am not yet wise. I cannot at the same time live in that state of Good and in this state of Evil; the two ideas do not harmonize, nor do Evil and Good exist together in the same person.
