" Nobody ever wanted to go to war, but if a war came your way, it might as well be the right war, about the most important things in the world, and you might as well, if you were going to fight it, be called " Rushdie," and stand where your father had placed you, in the tradition of the grand Aristotelian, Averroës, Abul Walid Muhammad ibn Ahmad ibn Rushd.

" Maybe in the case of true human, their mind, their soul, their consciousness flows through their bodies like blood, inhabiting every cell of their physical being, and so Aristotle was right, in humans the mind and body are one and cannot be separated, the self is both with the body and perishes with it too. She imagined that union with a thrill. How lucky human beings were if that was the case, she wanted to tell Geronimo who was and was not Ibn Rushd: lucky and doomed. When their hearts pounded with excitement their souls pounded too, when their pulses raced their spirits were aroused, hen their eyes moistened with tears of happiness it was their minds that felt the joy. Their minds touched the people their fingers touched, and when they in turn were touched by others it was as if two consciousnesses were briefly joined. The mind gave the body sensuality, it allowed the body to taste delight and to smell love in their lover's sweet perfume; not only their bodies but their minds, too, made love. And at the end the soul, as mortal as the body, learned the last great lesson of life, which was the body's death. "

" Ibn Mas'ud said, " When 'Umar died nine-tenth of all knowledge vanished with him." The people were shocked and said, " How can this be when among us now are still many of the great companions?" Ibn Mas'ud replied," I am not speaking of the knowledge of fiqh and the science of judgements, I'm speaking about the knowledge of Allah." This struggle of isolation, hunger, sleeplessness, weeping, fear and endless service to men was for this end. The journey is only for knowledge of Allah and the whole of it lies in detachment from everything that passes away. First from what is displeasing to Allah, then from one's self-illusion and desires, and then from all men and all otherness until there is only isolation and extreme nearness to Allah. "

" Two writings of al-Hassār have survived. The first, entitled Kitāb al-bayān wa t-tadhkār [Book of proof and recall] is a handbook of calculation treating numeration, arithmetical operations on whole numbers and on fractions, extraction of the exact or approximate square root of a whole of fractionary number and summation of progressions of whole numbers (natural, even or odd), and of their squares and cubes. Despite its classical content in relation to the Arab mathematical tradition, this book occupies a certain important place in the history of mathematics in North Africa for three reasons: in the first place, and notwithstanding the development of research, this manual remains the most ancient work of calculation representing simultaneously the tradition of the Maghrib and that of Muslim Spain. In the second place, this book is the first wherein one has found a symbolic writing of fractions, which utilises the horizontal bar and the dust ciphers i.e. the ancestors of the digits that we use today (and which are, for certain among them, almost identical to ours) [Woepcke 1858-59: 264-75; Zoubeidi 1996]. It seems as a matter of fact that the utilisation of the fraction bar was very quickly generalised in the mathematical teaching in the Maghrib, which could explain that Fibonacci (d. after 1240) had used in his Liber Abbaci, without making any particular remark about it [Djebbar 1980 : 97-99; Vogel 1970-80]. Thirdly, this handbook is the only Maghribian work of calculation known to have circulated in the scientific foyers of south Europe, as Moses Ibn Tibbon realised, in 1271, a Hebrew translation.
