Goethean science
Immanuel Kant in Prussia undertook a major rescue operation to preserve the validity of knowledge derived via reason (science), as well as of knowledge going beyond the rational mind, that is of human liberty and of life beyond simply an expression of 'the chance whirlings of unproductive particles' (Coleridge). Kant's writings had an immediate and major impact on Western philosophy and triggered a philosophical movement known as German idealism (Fichte, Hegel, Schelling), which sought to overcome and transcend the chasm Kant had formalized between the sense-based and the super-sensible worlds, in his attempt to 'save the appearances' (Owen Barfield), that is, to preserve the validity of scientific or rational knowledge as well as that of faith.
