Professor Dr. Ahmed Fouad Al-Ahwani says: "Human thought is an indivisible whole, its links are linked, and it develops from the past to the present, such that modern doctrines are not accessible to them except when they return to their origins from which they arose. Whenever you return to a origin, you see that in understanding it you need to return to the origin that preceded it, and the matter follows you until It reaches the first origin from which philosophy emerged, and it is, as you know, a Greek word that the Greeks coined to indicate this type of thinking. The first origin of philosophy in its meaning that we have come to terms with appeared in Greece in the sixth century BC, and it continued to grow until it reached its peak with Socrates, then Plato and Aristotle. These are lectures written and taught by Major Al-Ahwani with all his knowledge. He did not leave a single gap in the early history of Greek philosophy without including it in his lectures, beginning with the vanguards of Greek philosophy, revealing the texts of the ancients, passing through Ptoleus, Anaximendris, Pythagoras, Xenophanes, Heraclitus, Parmenides and others, ending with Gorgias and Antiphon. Hippas and Prodicus, documenting his hard work with the sources he resorted to. Are you surprised by these names, dear reader? Then you need to read this book.
