The morning sun on the horizon is both a symbol of renewal and a reminder of the past - it signals the dawn of a new day, a new vitality, and new experiences, yet it reminds us that our predecessors have witnessed their own morning suns and that we are recipients of their innovations and experiences. So it is natural that we have chosen the morning sun for the cover of this text, since it holds the promise of a bold, fresh approach in this new edition that does not ignore the best qualities of the earlier editions.
