Abstract
A desire to total up the results of the development of philosophical thought in the 20th century, to analyze the respects in which it has been distinctive, its successes and failures, has become clearly manifest in the bourgeois literature of the past two decades. There is nothing surprising in that fact as such. The mid-20th century is a chronological landmark of sufficient importance to impel thinkers to look behind them and give thought to the path they have traversed, while World War II and the cleavage of the world into two systems were trials of sufficient seriousness to compel a new look not only at the political but the intellectual history of the first half of this century. The fact that Marxism has become the most important factor in the entire ideological life of the contemporary world has destroyed the academic calm of bourgeois philosophy and compelled Western thinkers to undertake a review of their intellectual arsenal
