‘And what are the marks of innocence? Candour – a beautiful word – truthfulness, simplicity, a quite involuntary bearing of witness. The image that occurs to me here is a topical one, the image of a bell. A bell is made to speak out. What would be the value of a bell which never rung? It rings out clearly, it bears witness, it cannot speak without seeming like a call, a summons. A great bell is not to be silenced. Consider too its simplicity. There is no hidden mechanism. All that it is is plain and open; and if it is moved it must ring.’

Iris Murdoch, The Bell
