While this is titled a 'serious joke book' this book is not a joke. It is designed as a creative reference and sounding board for patients and therapists alike, focusing on finding meaning in the midst of therapy and disability. Its knowledge-based approach, using diagrams, sheds light on nuances and terpitudes not found in other encyclopedias. It is the second volume of the Dimensional Encyclopedia, the only volume devoted exclusively to psychology. The majority of the text establishes bases for knowledge in areas surrounding therapy and mental health, including a Tractatus of Psychology, a dualistic profile method, psychological deductions, and a method of psychic prediction, as well as updated materials. The philosophical approach is meant as an alternative to the sleazy and often simplistic pop-psychology books. This is an updated edition with the original cover reinstated and several updated sections, including a piece on 'not going wilden.' The D. Psy. T. is the second volume of the Dimensional Encyclopedia. The first volume is on philosophy.
