A collection of letters that the great scholar Ali Mustafa Mosharafa decided to compile in a book. Despite its many aspects, it revolves around one axis. It is science and its relationship to life. The author hopes that Arabic readers will find in it an incentive to pay attention to science in our country. There is no doubt about the necessity of this if we are truly serious about reforming what has been corrupted in our affairs. People are tired of the outdated methods of what is written and what is said, and they are looking forward to a new intellectual leadership based on facts, not illusions, and whose foundation is science, not the art of speech.
