Nasr’s expertise encompasses traditional culture (wisdom, religion, philosophy, science and art), Western thought from antiquity to the present day, and the history of science. He argues in favor of revelation, tradition, and what he considers “scientia sacra”, in opposition to rationalism, relativism, and modern western materialism.Nasr has not developed a new system of thought, but instead hopes to revive traditional doctrines that he believes have been forgotten in the modern world. He is content to recall what, according to him, corresponds to the many manifestations of a timeless wisdom.
