So. We are in the presence of Rita, she will guide you through this book. She co=wrote it with me. She had a A++ in the NLP class years ago. Her account in the first chapters. My extension, from Alexander P M van den Bosch, in the last part. A must read, now. Rita passed away at 15-3-2020 in Groningen, leaving all her IP to her man Bernard Ros.
