 In the first decade of the 20th century, Husserl considerably refined and modified his method into what he called “transcendental phenomenology”. This method has us focus on the essential structures that allow the objects naively taken for granted in the “natural attitude” (which is characteristic of both our everyday life and ordinary science) to “constitute themselves” in consciousness. (Among those who influenced him in this regard are Descartes, Hume and Kant.) As Husserl explains in detail in his second major work, Ideas (1913), the resulting perspective on the realm of intentional consciousness is supposed to enable the phenomenologist to develop a radically unprejudiced justification of his (or her) basic views on the world and himself and explore their rational interconnections.
