Alvin Mahrer writes: The emphasis of this book is on the field of psychotherapy mainly because I am much more familiar with this field than I am with other fields that value the creation of new ideas, fields such as literature or art, education or public relations, engineering or medicine, music or theater. I finally found a way for me to do psychotherapy at a point where many psychotherapists close their offices and find ways of enjoying life after psychotherapy.Somehow, I am not sure how or why, that was just about the point where I turned to the neighboring field of philosophy of science, as a 'mature student, ' with a passion to find what philosophy of science had to say about how to come up with creative new ideas.
