Throughout this book these questions are answered by analyzing the medical thinking and action and the physician-patient relationship. It analyzes this current dilemma in medical education, as well as, physician’s humanitarian tasks, process of medical reasoning (inquisitive and strategic thought) and different phases and steps of the medical care process.
