And, though at present you may find it a thing hard to believe, it is true none the less that for you, living in freedom and idleness and comfort, it is more easy to learn the lessons of Humility than it is for me, who begin the day by going down on my knees and washing the floor of my cell. For prison-life, with its endless privations and restrictions, makes one rebellious. The most terrible thing about it is not that it breaks one’s heart—hearts are made to be broken—but that it turns one’s heart to stone. One sometimes feels that it is only with a front of brass and a lip of scorn that one can get through the day at all. And he who is in a state of rebellion cannot receive grace, to use the phrase of which the Church is so fond—so rightly fond, I dare say—for in life, as in Art, the mood of rebellion closes up the channels of the soul, and shuts out the airs of heaven. Yet I must learn these lessons here, if I am to learn them anywhere, and must be filled with joy if my feet are on the right road, and my face set towards the “gate which is called Beautiful," though I may fall many times in the mire, and often in the mist go astray.
― Oscar Wilde, De Profundis
