The Collapse of Rationalism is a sustained philosophical assault on the foundations of modern rationalist thought. Drawing upon ancient sophistry, post-structuralist skepticism, and contemporary metaphysical doubt, the book dismantles the authority of logic, objectivity, and truth. It offers no alternative system—only a deliberate exposure of the illusions beneath all systems. This is a rare contribution to Arabic philosophical literature, now available in English in an expanded, fully annotated edition, complete with references that trace its engagement with both classical and contemporary philosophical sources.
