This book will help those who study philosophy, also those who do research on philosophy, those who have already studied philosophy, and those who enjoy keeping in touch with philosophy. I selected the most important points to debate in this book. I, myself, call this book a good quality of philosophy because I do not want to be outside of philosophy. Those who study philosophy should not feel useless, because the modernity wants to decrease the success of philosophy in human society. Most people think philosophy is just to study, but that is not true. If it was true, we should go back to challenge the Greek dictionary. I made it simple for everybody to understand that philosophy is not what people think in a negative manner; also, people who consider philosophy as a science are confused. That is not a problem, because everybody does not think the same. So readers will understand, in this book, philosophy is about the love of wisdom and more deep wisdom to think about something. Those who will read this book will be very satisfied, because most of the debates are well explained.
