forms will be subjected to travesty and degeneration, and will be swept away in the tide
of fashion. Rather than contribute to the further dissolution of the tradition, the sole
purpose of the tradition may be fulfilled if it serves to lead each one who submits to its
rigorous discipline, eventually, to discover for her self the golden thread of the canon
enshrined in the classical constructions.
The study of intelligible geometry leads to skill in
the intellectual arts because this science is one of the gates through which we move to
the knowledge of the soul, and that is the root of all knowledge.

Brotherhood of Purity, trans. Seyyed Hossein Nasr- quoted by Keith Critchlow, Islamic
