This book is written in answer to questions posed about the primary modes of human participation and recollection. Wach two consecutive chapters reflect on complementary aspects of this central theme. For example, the first two chapters of book I , entitled Participation, consider communion and its complement retreat. The call retreat reminds me to return to myself and reconfirm my personal dignity while the call to communion reawakens my need to be respected and affirmed by others, Likewise, in complementary chapters on works and play, it becomes clear that the I who laughs and loves and plays should be the I who works, for the productive I and the creative I are conjoined in every original human endeavor.
