The idea of the life-world: Life-world is a concept present in various texts about Husserl’s phenomenology. Some interpreters consider it a late and inconsistent concept present in The Crisis of European Sciences and Transcendental Phenomenology. In this paper, I argue that the idea of the life-world had already been thought in Husserl’s early texts such as Ideas II. This idea was firstly named as surrounding world, then world of experience, and finally life-world. However, despite the different nomenclature, the essence of (...) the life-world remains the same throughout his work. The life-world is a priori, transcendent, and co-given. I will analyze each of these characteristics and conclude in favor of a conceptual monism running through Husserl’s work. Keywords: Husserl, life-world, a priori, transcendent, co-given. (shrink)
