Dilthey defended his use of the term "Geisteswissenschaft" (literally, "science of the mind" or "spiritual knowledge") by pointing out that other terms such as "social science" and "cultural sciences" are equally one-sided and that the human mind or spirit is the central phenomenon from which all others are derived and analyzable. For Dilthey, like Hegel, "Geist" ("mind" or "spirit") has a cultural rather than a social meaning. It is not an abstract intellectual principle or disembodied behavioral experience but refers to the individual's life in its concrete cultural-historical context.
