 Second, Schleiermacher also rejects the content of Kant’s “categorical imperative” as specified by its central formulation: the requirement of consistency of a maxim under universalization. In On Religion and the Soliloquies Schleiermacher is rather inclined to champion Kant’s subordinate formula of a commitment to the welfare of humanity, though not in Kant’s sense of a common rational nature, but instead in Herder’s sense of all human beings in their diversities as well as their commonalities. (In On Religion he also discusses the historical dimension of this principle of humanity in a Herderian spirit, like Herder in Ideas for the Philosophy of History of Humanity [1784–91] emphasizing the important role that has been played by (Christian) religion in advancing it, and interpreting history as its progressive realization.)
