Abstract: Jan Patocka came to Freiburg in 1933 to follow Husserl and Heidegger on studying phenomenological philosophy. It is on this ground that he finished his teaching qualification thesis of The Natural World as a Philosophical Problem in 1936. Patocka had his own primal perspective in terms of approaching and discussing the problem of life-world albeit. At first he was influenced by Husserl’s concept of life-world and later by Heidegger’s concept of world. At the level of discussing phenomenology of life-world, he ultimately gave his own perspective and the passageway into it vis-à-vis Husserl and Heidegger. The passageway is manifested in three aspects: the transversely constructive, the longitudinally historical, and the methodological ones.
