Do we really have ancestors in thought and mind?
Do these ancestors have value in the field of modern science? Where are their books?
What is their status among the philosophers whose biographies we read, see their pictures, and stumble upon fragments of their sayings in books, magazines, and newspapers?
In order to answer these three questions, the author wrote this book. To demonstrate the virtue of these predecessors, and to establish their true status among the philosophers of the world, so that the doubter, the hesitant, and the imitator will know that that great civilization that came into existence fourteen centuries ago was not a civilization of war, attack, and matter, but rather it was a civilization of reason, science, and deep thought.
