AbstractDrawing on critical theorist Herbert Marcuse’s analysis of modern technological society in his 1964 book, One-Dimensional Man, this article argues that the forces of one-dimensionality that characterize citizens under capitalism have necessarily found their way into schools, leading to what we see as an epidemic of the one-dimensional student. Where other scholars have focused on the impacts of capitalism on schooling and possible structural reform efforts through educational policy, this analysis takes seriously the role of the individual in overcoming an all too easy tendency toward one-dimensional thinking. Applying Marcuse’s fundamental concepts of one-dimensionality, the authors point to the ways in which schools and society actively teach and promote one-dimensionality. Through this application of Marcuse to the field of education, the authors uncover the subtle ways that schools shape the consciousness of students, and in doing so perpetuate one-dimensional society. The article concludes with a number of solutions that reassess educational aims to be more in tune with the sharpening of critical consciousness, or what Marcuse calls negative thinking, for the sake of freedom of self and society.
