In the `Preface' to the Phenomenology of Spirit, Hegel outlines the dialectical method and contrasts it with two other approaches. On the one hand, there is `material thinking' (das materielles Denken): `a contingent consciousness that is absorbed only in material stuff', a form of thought which is rooted in existing conditions and cannot see beyond them. At the `opposite extreme' is the transcendent critical method of `argumentation' (das Räsonieren), which involves `freedom from all content and a sense of vanity towards (...) it'. The dialectical method must `give up this freedom'. It refuses `to intrude into the immanent rhythm of the Notion, either arbitrarily or with wisdom obtained from elsewhere'. Instead, it `sink[s] this freedom in the content, letting it move spontaneously of its own nature ... and then ... contemplate[s] this movement'. (shrink)
