Young Hegelian August Cieszkowski was one of the earliest philosophers to use the term "praxis" to mean "action oriented towards changing society" in his 1838 work "Prolegomena zur Historiosophie" ("Prolegomena to a Historiosophy"). Cieszkowski argued that while absolute truth had been achieved in the speculative philosophy of Hegel, the deep divisions and contradictions in man's consciousness could only be resolved through concrete practical activity that directly influences social life. Although there is no evidence that Karl Marx himself read this book, it may have had an indirect influence on his thought through the writings of his friend Moses Hess.
