When intellect can become "a luciferan [satanic] force"

'Nobody' can imagine - that nobody only includes modernist-fundamentalists, profane thinkers, etc. etc. - in today's world, that rational faculty of man may in fact be performing Satanic functions. The problem arises which shapes in misunderstanding this principle inherent in the nature of things, is b'cause the West doesn't differentiate between intellect and reason, as it may become clear to the reader from the following quote.

Question: "What can happen to the rational faculty if divorced from intellect and revelation?"

Seyyed Hossein Nasr: (in his Knowledge and Sacred): The rational faculty can become a luciferan [satanic] force.
