In his new book, Sebastian Morello has produced a brilliant excoriation of how and to what effect western civilisation has been possessed by Cartesian thought and what he subsequently terms “the black magic of modernity” – of which he argues our present society is an extreme manifestation. Morello’s central target in Mysticism, Magic, and Monasteries: Recovering the Sacred Mystery at the Heart of Reality is the supremacy of rationalism and Cartesian dualism – the fundamental distinction between mind and body posited in the 17th century – by which, he argues, European societies and the western Church have been misled to the point of complete inversion.
