“The seeker after truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them," the first scientist wrote, "but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration and not the sayings of human beings whose nature is fraught with all kinds of imperfection and deficiency. Thus the duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads, and, applying his mind to the core and margins of of its content, attack it from every side. he should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency.”

“Anyone who has learned the Quran and holds it lovingly in his heart will 'value his nights when people are asleep, his days when people are given to excess, his grief when people are joyful, his weeping when people laugh, his silence when people chatter and his humility when people are arrogant'. In other words every moment of life will be precious to him, and he should therefore be 'gentle', never harsh nor quarrelsome, 'nor one who makes a clamour in the market nor one who is quick to anger'.”

“It is He who is revealed in every face, sought in every sign, gazed upon by every eye, worshipped in every object of worship, and pursued in the unseen and the visible. Not a single one of His creatures can fail to find Him in its primordial and original nature. al-Futûhât al-Makkiyya”

“He who does not live in the way of his beliefs starts to believe in the way he lives.”

“No one is without Christianity, if we agree on what we mean by that word. It is every individual's individual code of behavior by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol - cross or crescent or whatever - that symbol is man's reminder of his duty inside the human race.”

“God (Nature, in my view) makes all things good; man meddles with them and they become evil. He fores one soil to yield the products of another, one tree to bear another's fruit. He confuses and confounds time, place, and natural conditions. He mutilates his dog, his horse, and his slave. He destroys and defaces all things; he loves all that is deformed and monstrous; he will have nothing as nature made it, not even himself, who must learn his paces like a saddle-horse, and be shaped to his master's taste like the trees in his garden.”

“Modern man has transformed himself into a commodity; he experiences his life energy as an investment with which he should make the highest profit, considering his position and the situation on the personality market. He is alienated from himself, from his fellow men and from nature. His main aim is profitable exchange of his skills, knowledge, and of himself, his "personality package" with others who are equally intent on a fair and profitable exchange. Life has no goal except the one to move, no principle except the one of fair exchange, no satisfaction except the one to consume.p97.”
