What are the causes of the crisis in psychology? Why do we find psychologies that study exclusive objects, with methods that are in turn opposed to each other? How can we set up a psychological science that escapes the dualistic and reductionist views that obstruct its historical and social character? How can these trends be overcome in clinical and educational practice? What is the place of Marxism in this task?

The historical significance of the crisis of psychology, by the Soviet Marxist psychologist Lev Vygotsky, allows us to address these questions in depth, demonstrating the central role of a materialist and dialectical position in the elaboration of a "general psychology" or dialectic of psychology that underpins the scientific discipline by overcoming its historical biases. A task that is now fully valid and relevant.

Written during the Russian Revolution and in the face of the tasks it posed, the book remained censored and distorted by Stalinism and academic manipulation for almost half a century. This edition of The Historical Meaning of the Crisis of Psychology, translated directly into Spanish from Russian by Alejandro Ariel González, who has already translated Pensamiento y habla and the Cuadernos de notas by the same author, constitutes the first complete version of the work worldwide. Published together with "The Socialist Transformation of Man" and "Thought", it allows one to enter the reading of Vygotsky and his "historical-cultural" theory through the door that censorship kept closed for decades: that of his Marxist philosophy and methodology. At the same time, it allows us to know the author's anti-capitalist and revolutionary strategic political objectives, directly linked to the struggle against any dogmatism.
