These Very Wise Voices

This non-fiction book is Denis' account of positively natured Voices that only he used to be able to hear. These Voices, a result of his schizophrenia, have also rewarded Denis with answers to many ancient questions, such as: the sound of a lone tree falling in a forest, the sound of one hand clapping (just hold one hand still!), which came first out of the chicken and the egg, and more.
