The paper draws from Lévinas fundamental ideas, as well as from other „dialogue philosophers“ (e.g. M. Buber, F. Rosenzweig, G. Marcel, E. Fromm). It outlines the wide impact which phenomenology and Judaism exerted on the origins of a philosophy, which is a defence of exterirority, and which puts one of its leaders (i.e. E. Lévinas) in the position opposite to Parmenides and Hegel. The paper discusses the menaning of Lévinas concept „The Other“, which is seen as the exterirority par excellence.
