An honest study of the causes of the Dark Ages and European renaissance will lead to the inevitable conclusion that Muhammad, may peace be on him, was the Light of the Dark Ages. John Davenport writes in an apology for Mohammed and the Koran: “It is in the compositions of Friar Bacon, who was born in 1214, and who learned the Oriental languages, that we discover the most extensive acquaintance with the Arabian anthors. He quotes Albumazar, Thabet-Ebu-Corah, Ali Alhacer, Alkandi, Alfraganus and Arzakeb; and seems to have been as familiar with them as with the Greek and Latin classics, especially with Avicenna, whom he calls ‘the chief and prince of philosophy.’ The great Lord Bacon, it is well known, imbibed and borrowed the first principles of his famous experimental philosophy from his predecessor and namesake Roger Bacon, a fact which indisputably establishes the derivation of the Baconian philosophical system from the descendants of Ishmael and disciples of Mohammed.” In a short paragraph, John Davenport has very precisely identified all the links in the human intellectual evolution. Additionally, his book, which is available in Google books, is a master piece in the defence of the Prophet Muhammad, may peace be on him. Read his two page Preface and he is standing shoulder to shoulder with other great defenders of the Prophet Muhammad in the Western world, like Thomas Carlyle. Unfortunately, some Western scientists and historians propose the European science to be some sort of magical wand and what preceded it as not good enough or label it as pre-science or mystical science etc!
The picture is of Cave of Hira where the prophet had his first revelation!
