“Those who devote themselves eagerly to the mathematical sciences ought to be restrained. Even if their subject-matter is not relevant to religion, yet, since they belong to the foundations of the philosophical sciences, the student is infected with the evil and corruption of the philosophers. Few there are who devote themselves to this study without being stripped of religion and having the bridle of godly fear removed from their heads.” – Abu Hamid Muhammad ibn Muhammad al-Ghazali, The Deliverance from Error (trans. Watt)
