This article evaluates the "metaphysical critique" of contemporary science by the Islamic philosophical theologian Naquib al-Attas in his Prolegomena to a Metaphysics of Islam. I argue that al-Attas' critique is dialectically inappropriate because it relies on specific, and non-publicly verifiable, interpretations of revelation and spiritual intuition. I contrast this with the work of Edmund Husserl, especially in his The Crisis of European Sciences and Transcendental Phenomenology, which I show can sustain a viable critique of science through the phenomenological grounding of public reason. I also assess the prospect for Islamic engagement with Husserl on this topic.
