In the beginning, science, knowledge and beliefs were a single unit, in which magic was mixed with art, crafts and religion. In the Middle Ages, scholars combined several specializations. For example, Ibn Sina was a physician, philosopher and poet all at once. However, with the advancement of science in the modern era, specialization increased, and each science became independent in itself. University studies became more and more specialized in a specific field, to the point that we find that a medical student does not know much about philosophy, and a philosophy student knows only a little about the sciences. With the increasing demands of difficult and complex economic life and the increasing pressures, students focused on obtaining good grades in university classes only to increase their job opportunities. With the pressures of work itself, there was no longer time for reading, and gradually, general culture lost its significant advantage, which provided the individual with great benefits. Learning about the various humanities enriches the individual mentally and spiritually. The mind's innovative capacity is enriched by combining various sciences, and it also gives it a human character: because it makes one realize that human values ​​are absolute and very broad, which broadens one's outlook on life, and through it one realizes that there is no single perspective on the difficulties one faces in life. As we comprehend the breadth of human thought, we realize that daily problems are nothing but a simple thing compared to the vast, infinite world. The effect of this is the effect of seeing the endless sea or desert. Then you know that the horizons of life are vast and do not stop at the limited, private, narrow daily life and the prison of the self. From here the importance of this book appears, as it encompasses various general intellectual fields: philosophy, religion, science, politics, economics, sociology, psychology, and the arts. This book is distinguished by explaining the essential terms and ideas in these fields. By the end of reading each chapter, the reader will have a comprehensive and deep knowledge at the same time - of the basics of each field, which saves him the trouble of reading many books in many fields to understand them, or perhaps whets his appetite to follow what is new in each field with its details and subtleties.
