“In sharp contrast to his medical research, Razi’s ventures into religion earned him nothing but abuse.63 The very names of Razi’s three treatises on religion say it all: The Prophets’ Fraudulent Tricks; The Stratagems of Those Who Claim to Be Prophets; and On the Refutation of Revealed Religions. Razi did not mince words: If the people of [a given] religion are asked about the proof for the soundness of their religion, they flare up, get angry and spill the blood of whoever confronts them with this question. They forbid rational speculation, and strive to kill their adversaries. This is why truth became thoroughly silenced and concealed.”

“Having reviewed diverse theories and hypotheses on the waning of the Age of Enlightenment in Central Asia, it is now time to step back and raise a larger question: does it really require an explanation? The assumption behind our search for causes is that if one or another factor had not come into play, the movement of thought would have continued. But that great period of intense cerebration, that age of inquiry and innovation, had lasted for more than four centuries. If more information on the centuries preceding the Arab invasion had survived, we might confidently extend that period of flowering even further back in time. Even without this addition, the Age of Enlightenment was five times longer than the lifetime of Periclean Athens; a century longer than the entire history of the intellectual center of Alexandria from its foundation to the destruction of its library; only slightly shorter than the entire life span of the Roman Republic; longer than the Ming or Qing dynasties in China and the same length as the Han; about the same length as the history of Japan from the founding of the Tokugawa dynasty to the present; and of England from the age of Shakespeare to our own day. As they say in the theater world, it had a long run. It is well and good to speak of causes of the decline of the passion for inquiry and innovation, or of some supposed exhaustion of creative energies. But just as we feel little need to discover the cause of a nonagenarian’s death, we need not inquire too urgently into the cause of the waning of this remarkable age. Of course, the question of why the region as a whole remained in a state of backwardness from the end of the Age of Enlightenment down to recent times is vitally important, but it involves many factors besides those that came into play in the intellectual decline. It should form the subject of another book.”
