Materialism ja empiriokrititsism : kriitilisi märkmeid ühe reaktsioonilise filosoofia kohta

Materialism and Empirio-criticism is a philosophical work by Vladimir Lenin, published in 1909. It was an obligatory subject of study in all institutions of higher education in the Soviet Union, as a seminal work of dialectical materialism, a part of the curriculum called "Marxist–Leninist Philosophy". Lenin argued that human minds are capable of forming representations of the world that portray the world as it is. Thus, Lenin argues, our beliefs about the world can be objectively true; a belief is true when it accurately reflects the facts. According to Lenin, absolute truth is possible, but our theories are often only relatively true. Scientific theories can therefore constitute knowledge of the world.
