Arcadia:

Arcadia: "the perfect marriage of idea and high comedy?" Throughout Tom Stoppard's Arcadia, intellectual ideas and themes are explored. Set in two contrasting timeframes, it shows history in the making and history in the discovering - both by groups of mostly highly enlightened individuals.

Stoppard is making a statement in this play: that history may not always be right, but that is not important if it teaches people something. Maybe a Romantic view of life with a hint of Reason?
