His thoughts, whether conceived in a white heat of frenzy, or with deliberate coolness and sly calculations for the main chance, were probably not written down in any definite manner during his lifetime. It is not even certain whether he could read or write. He delighted in the appellation, "The Illiterate Prophet," possibly on account of his humility and possibly because he knew that inspired ignorance had been the indisputable prerogative of all successful prophets in the past. Indeed, the very fact that he was unlearned was rightly supposed to increase the miraculous nature of his revelations. As he tossed the divine emanations from his lips, they were sometimes recorded by hireling scribes upon palm leaves, leather, stones, the shoulder blades or ribs of camels and goats. But often they were not immediately written down at all; the Prophet would go around spouting forth his utterances to his followers, who, trained from infancy to memorize verses and songs of every sort with infallible precision, would piously commit them to memory. Such is the Koran, and through its instrumentality, Allah the Wise, The Only Wise, revealed his immutable decrees: to the good, the rewards of a Paradise that utterly beggared the Christian Heaven; to the bad, the punishments of a Hell that contained an infinity of such refined tortures of heat, and even of cold as neither the most imaginatively gifted Jew or Christian had yet conceived. Reinach aptly states, "It is humiliating to the human intellect to think that this mediocre literature has been the subject of innumerable commentaries and that millions of men are still wasting time in absorbing it." Over one hundred and sixty million are adherents of the Koran. In an objective analysis, excluding the emotional factors of religious bias, Mohammed would as unquestionably be considered a victim of mental disturbances as an individual living in our own day and manifesting the same symptoms. Mohammed was the subject of illusions, hallucinations, and delusions. He had suicidal tendencies, and he had alternating periods of exhilaration and depression. To simply assert that he was an epileptic does not explain these symptoms. For epileptics cannot throw a fit at will. However, we know that ten per cent of epileptics develop mental diseases, no particular psychosis but a loss of mental and moral sense. There are two types of individuals who can produce seizures such as Mohammed was wont to evoke at will. One type is the hysterical, and the other is that degraded individual who for the sake of collecting alms will place a piece of soap in his mouth, enter a crowded street, fall to the ground, and proceed to foam at the mouth and twist and contort himself as an epileptic does. That is the charlatan, the faker, and that brings us to the second aspect of his (Mohammed's) character.
