Each of these schemes has its advantages; on the whole the last is probably best, since it provides
for a certain variety in the over-all program and makes it possible
for those who attend not only to take part in one large meeting where the whole group is stimulated by
consideration of a single topic over a considerable period of time, but also to share in special «interest groups» which will give them the opportunity to follow
up lines of thought that particularly interest them or to explore
problems that are peculiarly relevant to their own needs and concerns.
