"Although the text may be strong and durable and able to support a lifetime's work, it cannot be taken for granted and there is no guarantee of permanent possession. It may be mislaid or even lost, and retrieval is very difficult. It may lie dormant, and be discovered late in life after a long struggle... Why it should be that some people have this sort of text while others do not, and what 'meaning' it has, is not something which lends itself to argument. Nor is it up to the artist to decide how important it is, or what value it has for other people."
