8This book is intended to retrace the origin, existence, and purpose and tasks of law in its application in human life from the past to the era of modern civilized human life, which in the course of long human life already have undergone various changes. This book is not purposed solely for people who have a legal profession or legal education, but it is intended for all people who are interested in reading, whether they have legal based education or not. I do not intend to provide legal education, but only give a glimpse of the introduction, with the aim that the law does not become something 'mysterious' that is only mastered by experts and people of the legal profession. I hope this book is useful in adding to the repertoire of legal literatures.
