“Museums hold collections in trust for future generations. It is our responsibility to see that these objects—representing the cultural heritage of more than 8,000 years of civilization—are passed on to the next generation . . . . The next generation may choose to look at objects afresh—without our carefully collected input—and form its own opinions about their purpose, history or intended use. What is important is that future observers have at their disposal the records of what was known or believed at the time.”
