Philosophical schools

Philosophical schools did not stop at analyzing social systems and trying to understand them except in order to work on drawing new lines for a better society by inventing new systems that work to develop and promote society. If they had contented themselves with the stage of understanding and recording, they would not have been philosophical schools worthy of bearing this name. In ordinary schools, this task is sufficient. As for philosophical schools, by virtue of their function of guidance and guidance, they play the role of intellectual leadership that takes the nation forward. This does not mean that all philosophical schools were innovative in thought. Their owners delved deeply into research, shared in their sensitivity to society's demands, and worked for its well-being and development. Schools are afflicted with what afflicts every living being, such as old age. Schools arose and then died, and some of them remained and continued to live by teaching the books of the ancients.
