Julian Leopold Ochorowicz (Polish pronunciation: ['juljan lɛˈɔpɔld ɔxɔˈrɔvit͡ʂ]; outside Poland also known as Julien Ochorowitz; Radzymin, 23 February 1850 – 1 May 1917, Warsaw) was a Polish philosopher, psychologist, inventor (precursor of radio and television), poet, publicist, and leading exponent of Polish Positivism.
Aleksander Świętochowski (18 January 1849 – 25 April 1938) was a Polish writer, educator, and philosopher of the Positivist period that followed the January 1863 Uprising.
He was widely regarded as the prophet of Polish Positivism, spreading in the Warsaw press the gospel of scientific inquiry, education, economic development, and equality of rights for all, without regard to sex, class, ethnic origin or beliefs. His was a nuanced vision, however, that took account of the shortcomings of human nature; like H.G. Wells, he advocated that power in society be wielded by the most enlightened among its members.
