Cieszkowski coined the term historiosophy in his 1838 work
Prolegomena zur Historiosophie (
Prolegomena to a Historiosophy), a revision of the Hegelian
philosophy of history. He adopted a threefold division of human history from medieval
millenarians such as
Joachim of Fiore ( 1135–1202) and mixed it with Hegelian categories and concepts. He is arguably the creator of the "
philosophy of action". • Cieszkowki's
first period of history was that of
antiquity. • The
second period was the
Christian era, which represented the birth of reflectiveness, a turning inwards and upwards from natural sensual immediacy toward the universal and abstract. The spirit existed "for itself" (
für sich). This period was marked by an intolerable duality between the opposed worlds of the God and temporal existence, spirit and matter, action and thought. The Hegelian philosophy of spirit, thought and universality at the expense of will, matter and particularly the (Hegelian) spirit had not yet experienced the division of mind and body and living in a primal pre-reflective unity with nature, mainly expressing itself through art. The spirit was "in itself" (
an sich) in Hegelian jargon. The existence represented the apotheosis and supreme manifestation of this period of history. • The
third period of history was the "post-Hegelian" era in which the dualisms of the last were overcome and superseded. The one-sided emphasis on thought in the Christian era would be overcome and the spirit would assimilate nature to itself as well. Thus philosophy would come to an end as the synthesising and self-actualising activity of the spirit now took the form of creative practical activity. This final stage of the development of spirit represents the ultimate synthesis of opposites: God and world, necessity and freedom, desire and duty, Heaven and Earth are all as one. Cieszkowski's later works,
Gott und Paligenesie (
God and Palingenesis) (1842) and
Ojcze Nasz (
Our Father, 1848–1906, four volumes), reformulate his triad in much more explicitly religious terms. The three eras are expressed as those of God the Father, the Son and the Holy Spirit. He stresses the role of the Catholic Church and accords a significant world-transforming role to the Slavs (a common theme in the
Messianistic philosophy current in Poland at the time) in the process through which the Holy Spirit would emerge. Cieszkowski's belief in a personal God, it has been argued, disqualifies him as one of the
Left Hegelians, differentiated from Hegel's
more orthodox followers by their generally critical attitude to religion and Christianity. The Left certainly did not count him as one of their own, even though some of its members soon took up the idea of the unity of philosophy of action. On the other hand, Cieszkowski did incorporate an elaborate system of social reforms into his philosophy and was strongly influenced by the French socialist tradition, which was often overtly religious, and thus did not share the characteristic political conservatism of the "Right Hegelians". ==Legacy==
