There's an interesting debate going on about how Peggy should start her
collection (Which, incindentally is a sure-fire way of getting a heated

 From the past to the present - - historical

 From the simplest to the most complex - - chemical?

 From the visible to the invisible - - biological?  [Spiritual.  -Dave]

 From the specific to the general - - mathematical?

 From the known to the unknown - - philosophical?

 From the local to the global - - the geographical?

 From the familiar to the unfamiliar - - the successful? ;-)
