In the beginning, sciences, knowledge, and beliefs were a single entity, where magic was intertwined with art, craft, and religion. In the Middle Ages, scholars combined several disciplines; for example, Avicenna was a physician, philosopher, and poet simultaneously. However, with the advancement of science in the modern era, specialization increased, and each science became independent, and university studies became more and more specialized in a particular field. We even find that a medical student does not know much about philosophy, and a philosophy student knows only a little about science. With the increasing demands of difficult and complex economic life and the exacerbation of pressures, students' attention has been focused on obtaining good grades in university to increase their job opportunities only. With the pressures of work itself, there is no longer time for reading, and little by little, general culture has lost its significant advantage, which used to grant individuals many benefits. Getting to know various human sciences enriches the individual mentally and spiritually, as the creative ability of the mind is nourished by mixing various sciences, and it also gives it a human character because it confirms that human values are absolute and very broad, which expands one's view of life, and through it, one realizes that there is no single perspective on the difficulties one faces in life. With our understanding of the breadth of human thought, we realize that daily problems are but a simple thing compared to the vast, endless world. The effect of this is like seeing the endless sea or desert. Then you learn that the horizons of life are vast and do not stop at the limited, specific, narrow daily life and the prison of the self. Hence, the importance of this book appears, as it covers various general intellectual fields: philosophy, religion, science, politics, economics, sociology, psychology, and arts. This book is characterized by explaining the essential terms and ideas in these fields, so by the end of reading each chapter, the reader will have a comprehensive and deep understanding simultaneously of the basics of each field, which saves them the trouble of reading many books in many fields to grasp them, or perhaps it whets their appetite to follow new developments in each field with its details and intricacies. The book is also characterized by having all its terms organized in the form of a glossary, which makes it easy for the reader to find any term they wish.
