About Stanisław Staszic

Stanisław Wawrzyniec Staszic was a Polish philosopher and writer. A leading figure in the Polish Enlightenment, he was also a Catholic priest, geologist, poet, translator and statesman. A physiocrat, monist, pan-Slavist and laissez-fairist, he supported many reforms in Poland. He is particularly remembered for his political writings during the "Great (Four-Year) Sejm" (1788–1792) and for his large support towards the Constitution of 3 May 1791, adopted by that Sejm.
