What have we learned? Where are we going? And some lessons from the past

The study of clusters and associations of stars, which presumably have common ages, abundances, and histories, provides an excellent data. base for testing theories of stellar evolution, physical processes in stars, and the interactions of stars with their nascent clouds, circumstellar disks, and binary companions. This second of the "Three Islands" Euroconferences discussed all of these issues in depth. I will summarize the conference first through a series of revealing quotes to provide the flavor of the meeting, and then highlight nine of the major issues discussed by several speakers to show how far we have come in the last few years and the unsolved problems that deserve further study. Hopefully, at future meetings we will learn of the solutions to these problems. Finally, we can learn from the first astronomer to study clusters, Gallileo Galilei, an appreciation for the awe of discovery.
