How did Husserl describe the life-world as different from scientific knowledge?

In his later work, The Crisis of European Sciences and Transcendental Phenomenology, Edmund Husserl distinguished the life-world (Lebenswelt) from scientific knowledge by emphasizing their different modes of experience and origin.12

Husserl described the life-world as the world as it is immediately and directly experienced in the subjectivity of everyday life, encompassing individual, social, perceptual, and practical experiences. In contrast, scientific knowledge is characterized by an objectivistic, physicalist approach that employs the methods of the mathematical sciences of nature.31

Husserl argued that scientific knowledge originates within the life-world, yet the sciences often forget this subjective foundation, leading to a "crisis" where the scientist and the accomplishing subject are ignored. He maintained that the truth of the life-world is not an inferior form of truth compared to scientific exactness; rather, it is the foundational truth presupposed by all scientific research. Consequently, Husserl advocated for an ontology of the life-world to systematically analyze the constitutive acts that underpin all scientific constructions of meaning.13
