Only man can stop being fully man. He can ascend above all degres of universal existence and by the same token fall below the level of the basest of creatures.
Seyyed Hossein NasrThe traditional doctrine of man and not the measurement of skulls and footprints is the key for the understanding of that anthropos who, despite the rebellion of Promethean man against Heaven from the period of Renaissance and its aftermath, is still the inner man of every man, the reality which no human being can deny wherever and whenever he lives, the imprint of a theomorphic nature which no historical change and transformation can erase completely from the face of that creature called man.
Seyyed Hossein NasrSufis have always been those that have tried to purify the ethics of Islam and society. And they don't have their hands cut off from the external action at all. For example, the bazaar in which the Sufis were very strong always dominated economic life in Islamic world. They could give a much more sane and Islamic form of activity when the economic life of Islam moved out of the bazaar to new parts of Islamic cities with modernized Muslims, who took it in another light and it became very, very anti Islamic, and much against many of the most profound practices of Islamic societies.
