Imperfection is in some sort essential to all that we know of life. It is the sign of life in a mortal body, that is to say, of a state of progress and change. Nothing that lives is, or can be rigidly perfect; part of it is decaying, part nascent.
John RuskinThe greatest glory of a building is not in its stones, nor in its gold. Its glory is in its Age, and in that deep sense of voicefulness, of stern watching, of mysterious sympathy... which we feel in walls that have long been washed by the passing waves of humanity.
