The invention of Cartesian methodological approach has revolutionized science. However, regardless of its undeniable achievements, this approach has also its limitations.
In order to uncover some of these limitations, first, we elaborate on Husserl's discussion of John Locke's naturalism and naturalistic concept of the world and man. In the second part, we discuss Husserl's clash with the new science, i.e., ethnology, as further developed by Lévi-Bruhl.
Husserl considered ethnology as a potential way for developing a new kind of knowledge about man going beyond the boundaries of (natural) sciences that reduce man to a mere object in the world.
