German idealism
Neo-Kantianism refers broadly to a revived type of philosophy along the lines of that laid down by Immanuel Kant in the 18th century, or more specifically by Schopenhauer's criticism of the Kantian philosophy in his work "The World as Will and Representation" (1818), as well as by other post-Kantian philosophers such as Jakob Friedrich Fries and Johann Friedrich Herbart. It has some more specific reference in later German philosophy.
Józef Kalasanty Szaniawski
From 1802 to 1808 Szaniawski published his philosophical works in rapid succession. He expounded Kant's philosophy, but with a special purpose—to turn people's minds toward learning; and, in learning, to break with Enlightenment philosophy, which he condemned for dogmatic unbelief and morally damaging hedonism. He was the first to lead the campaign against the Enlightenment in Poland. He became an apostle of German philosophy and was the first to introduce it into Poland.
