Abstract
The focus of the article is on the risks of a religious predominance over secular philosophy and the eigenrationality of the legal system. This is a tendency, not a necessity, that can be attributed to Islam as opposed to Christian thinking. The latter has gradually adopted major components of the pagan Roman-Greek culture in late antiquity, philosophy and Roman law in particular. Islam has tolerated the spread of Greek philosophy in medieval ages, but its core has not been touched by this exchange. Islamic law cannot easily adapt to the historical transformation of society because its essence is enshrined in the Coran which is regarded as being the word of God himself. Islam „as such“ is not a monolithic religion, however, it allows for the rise of sectarian movements that plead for the possibility of a Coran „without interpretation“. The autonomy of law, in particular, is opposed by many groups because they fear the risks of a secularisation of culture.
