The latest theory of intelligence is that it is multiple, not just the scholastic aptitude or "school smarts" of IQ tests. The great composers had high levels of musical intelligence, great writers linguistic intelligence, Olympic gold medalists body-kinesthetic intelligence, and the lives and works of Moses, Buddha, Jesus, and Muhammad reflected high spiritual intelligence (SIQ). This book explains SIQ, in past and recent history, with self-help exercises to identify and further develop your own SIQ.
