 An often overlooked source of ecological ideas is the work of the neo-Marxist Frankfurt School of critical theory founded by Max Horkheimer and Theodore Adorno (Horkheimer and Adorno 1969). While classical Marxists regard nature as a resource to be transformed by human labour and utilized for human purposes, Horkheimer and Adorno saw Marx himself as representative of the problem of “human alienation”. At the root of this alienation, they argue, is a narrow positivist conception of rationality—which sees rationality as an instrument for pursuing progress, power and technological control, and takes observation, measurement and the application of purely quantitative methods to be capable of solving all problems. Such a positivistic view of science combines determinism with optimism. Natural processes as well as human activities are seen to be predictable and manipulable. Nature (and, likewise, human nature) is no longer mysterious, uncontrollable, or fearsome. Instead, it is reduced to an object strictly governed by natural laws, which therefore can be studied, known, and employed to our benefit. By promising limitless knowledge and power, the positivism of science and technology not only removes our fear of nature, the critical theorists argue, but also destroys our sense of awe and wonder towards it. That is to say, positivism “disenchants” nature—along with everything that can be studied by the sciences, whether natural, social or human.
