Taking into account where he was, the interest that had first brought him there when he had been free to keep away, and the gentle presence that was equally inseparable from the walls and bars about him and from the impalpable remembrances of his later life which no walls nor bars could imprison, it was not remarkable that everything his memory turned upon should bring him round again to Little Dorrit. Yet it was remarkable to him; not because of the fact itself; but because of the reminder it brought with it, how much the dear little creature had influenced his better resolutions.I read this to Tom and he said, "That is just simply true." Yes. It is. Little Dorrit ... what a book.
None of us clearly know to whom or to what we are indebted in this wise, until some marked stop in the whirling wheel of life brings the right perception with it. It comes with sickness, it comes with sorrow, it comes with the loss of the dearly loved, it is one of the most frequent uses of adversity.
Charles Dickens, Little Dorrit
