“Man has been going through three kinds of wars. One is with nature; another is with other people and third is with himself.”

“the Qur’ān appears to be interested in three types knowledge for man. One is the knowledge of nature which has been made subservient to man, i.e., the physical sciences. The second crucial type is the knowledge of history (and geography): the Qur’ān persistently asks man to "travel on the earth" and see for himself what happened to bygone civilizations and why they rose and fell. The third is the knowledge of man himself.”

“Man has been reared by his errors: first he never saw himself other than imperfectly, second he attributed to himself imaginary qualities, third he felt himself in a false order of rank with animal and nature, fourth he continually invented new tables of values and for a time took each of them to be eternal and unconditional...If one deducts the effect of these four errors, one has also deducted away humanity, humaneness, and 'human dignity'.”

“But man is a part of nature, and his war against nature is inevitably a war against himself.”

“There will always be another war, Gillia.” He allowed his cynicism to seep through. “Do you know why? Because there will always be bigots and cowards and power-mad devils in positions of omnipotence. Look around you. There has been war here since time began. It’s nature. Animals kill each other for survival, for territory… and for the taste of blood in their mouths. Man is no different.”

“There are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, and the third is useless..”
