The preceding 39 chapters concern a vast amount of information in a synoptic fashion. Obviously, much has been omitted or reduced in order to have brevity. For those needing more, 1,500 references are in the back which will in turn lead to other papers. The studies quoted provide at least some level of detail in order to be initially evaluated for validity and reliability. What follows in the epilogue is a synopsis of some important features and key points which were stressed in the full text. Promising directions and concepts are indicated.
