Fortunately, judgments of past events and our evaluations of historical figures do not remain static. They change, as new information becomes available, critical viewpoints alter, and new schemes of value develop. As a concrete example, we might mention the different opinions that have been offered concerning an individual such as Paracelsus, who lived from 1493 to 1541.
