The Positivist philosophy that took form in Poland after the January 1863 Uprising was hardly identical with the philosophy of Auguste Comte. It was in fact a return to the line of Jan Śniadecki and Hugo Kołłątaj—a line that had remained unbroken even during the Messianist period—now enriched with the ideas of Comte. However, it belonged only partly to philosophy. It combined Comte's ideas with those of John Stuart Mill and Herbert Spencer, for it was interested in what was common to them all: a sober, empirical attitude to life.
