A new edition of a foundational work of cognitive science that outlines a theory of the development of specifically human higher mental functions. Since it was introduced to the English-speaking world in 1962, Lev Vygotsky's Thought and Language has become recognized as a classic foundational work of cognitive science. Its 1962 English translation must certainly be considered one of the most important and influential books ever published by the MIT Press. In this highly original exploration of human mental development, Vygotsky analyzes the relationship between words and consciousness, arguing that speech is social in its origins and that only as children develop does it become internalized verbal thought. In 1986, the MIT Press published a new edition of the original translation by Eugenia Hanfmann and Gertrude Vakar, edited by Vygotsky scholar Alex Kozulin, that restored the work's complete text and added materials to help readers better understand Vygotsky's thought. Kozulin also contributed an introductory essay that offered new insight into Vygotsky's life, intellectual milieu, and research methods. This expanded edition offers Vygotsky's text, Kozulin's essay, a subject index, and a new foreword by Kozulin that maps the ever-growing influence of Vygotsky's ideas.

Since it was introduced to the English-speaking world in 1962, Lev Vygotsky's highly original exploration of human mental development has become recognized as a classic foundational work of cognitive science. Vygotsky analyzes the relationship between words and consciousness, arguing that speech is social in its origins and that only as children develop does it become internalized verbal thought. Now Alex Kozulin has created a new edition of the original MIT Press translation by Eugenia Hanfmann and Gertrude Vakar that restores the work's complete text and adds materials that will help readers better understand Vygotsky's meaning and intentions. Kozulin has also contributed an introductory essay that offers new insight into the author's life, intellectual milieu, and research methods. Lev S. Vygotsky (1896-1934) studied at Moscow University and acquired in his brief lifespan a nearly encyclopedic knowledge of the social sciences, psychology, philosophy, linguistics, literature, and the arts. He began his systematic work in psychology at the age of 28, and within a few years formulated his theory of the development of specifically human higher mental functions. He died of tuberculosis ten years later, and Thought and Languagewas published posthumously in 1934. Alex Kozulin studied at the Moscow Institute of Medicine and the Moscow Institute of Psychology, where he began his investigation of Vygotsky and the history of Soviet psychology. He emigrated in 1979 and is now Associate Professor of Psychiatry (Psychology) at Boston University. He is the author of Psychology in Utopia: Toward a Social History of Soviet Psychology(MIT Press 1984).

2012 Reprint of 1962 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. Vygotsky's closely reasoned, highly readable analysis of the nature of verbal thought as based on word meaning marks a significant step forward in the growing effort to understand cognitive processes. Speech is, he argues, social in origins. Speech is learned from others and, at first used entirely for affective and social functions. Only with time does it come to have self-directive properties that eventually result in internalized verbal thought. A classic work.
