The article offers an interpretation of Emmanuel Lévinas' Totality and Infinity taking as its starting point the term "hospitality", which plays a key role in his work. Hospitality opens up the way to another conception of ethics which differs from traditional moral philosophy and presents subjectivity as open towards the outside, towards the extraneous and infinite, receiving the other. In this sense, what really matters in ethics does not begin with the I, but comes from outside the I which is also the side of the other, who initiates the I into ethics. In the end, the article tries to show what kind of "society" such an ethics of hospitality leads to and how this becomes reflected in Lévinas own writing.
