The purpose of this article is to consider the dialogism as a meaning-determining principle in Albert Schweitzer's concept of ethics and life. The scientific novelty of the study lies in the fact that it considers Schweitzer's ethical imperative to be an imperative whose basis is a dialogue between two subjects, one of which is myself and the other can be the whole world in all the variety of life. Separately, it considers the issue of the search for existential meaning within the idea of a dialogic moral paradigm of the whole human existence. The results obtained show that dialogism can be seen as one of the inalienable foundations of Albert Schweitzer's ethical concept.
