The period of Messianism, between the November 1830 and January 1863 Uprisings, reflected European Romantic and Idealist trends, as well as a Polish yearning for political resurrection.
"[A] Positivist", wrote the novelist Bolesław Prus' friend, Julian Ochorowicz, was "anyone who bases assertions on verifiable evidence; who does not express himself categorically about doubtful things, and does not speak at all about those that are inaccessible.
Rigorously-trained Polish philosophers made substantial contributions to specialized fields—to psychology, the history of philosophy, the theory of knowledge, and especially mathematical logic.
The phenomenologist Roman Ingarden did influential work in esthetics and in a Husserl-style metaphysics; his student Karol Wojtyła acquired a unique influence on the world stage as Pope John Paul II.
The formal history of philosophy in Poland may be said to have begun in the fifteenth century, following the revival of the University of Kraków by King Władysław II Jagiełło in 1400.
[8] Vitello's Perspectiva additionally made important contributions to psychology: it held that vision per se apprehends only colors and light while all else, particularly the distance and size of objects, is established by means of association and unconscious deduction.
[11] In physics, logic and ethics, Terminism (Nominalism) prevailed in Kraków, under the influence of the French Scholastic, Jean Buridan (died c. 1359), who had been rector of the University of Paris and an exponent of views of William of Ockham.
[14] When Nominalism was revived in western Europe at the turn of the sixteenth century, particularly thanks to Jacques Lefèvre d'Étaples (Faber Stapulensis), it presently reappeared in Kraków and began taking the upper hand there once more over Thomism and Scotism.
[14] Thus Poland had made her appearance as a separate philosophical center only at the turn of the fifteenth century, at a time when the creative period of Scholastic philosophy had already passed.
He arrived at the heliocentric thesis (as he was to write in a youthful treatise) "ratione postea equidem sensu": it was not observation but the discovery of a logical contradiction in Ptolemy's system, that served him as a point of departure that led to the new astronomy.
[19] In the early sixteenth century, Plato, who had become a model for philosophy in Italy, especially in Medicean Florence, was represented in Poland in some ways by Adam of Łowicz, author of Conversations about Immortality.
Sebastian Petrycy of Pilzno (1554–1626) laid stress, in the theory of knowledge, on experiment and induction; and in psychology, on feeling and will; while in politics he preached democratic ideas.
[22] Yet another Renaissance current, the new Stoicism, was represented in Poland by Jakub Górski (c. 1525 – 1585), author of a famous Dialectic (1563) and of many works in grammar, rhetoric, theology and sociology.
[23] A later, purer representative of Stoicism in Poland was Adam Burski (c. 1560 – 1611), author of a Dialectica Ciceronis (1604) boldly proclaiming Stoic sensualism and empiricism and—before Francis Bacon—urging the use of inductive method.
[23] A star among the pleiade of progressive political philosophers during the Polish Renaissance was Andrzej Frycz Modrzewski (1503–72), who advocated on behalf of equality for all before the law, the accountability of monarch and government to the nation, and social assistance for the weak and disadvantaged.
Jonston was tutor and physician to the Leszczyński family, a devotee of Bacon and experimental knowledge, and author of Naturae constantia, published in Amsterdam in 1632, whose geometrical method and naturalistic, almost pantheistic concept of the world may have influenced Benedict Spinoza.
[28] In 1689, in an exceptional miscarriage of justice, a Polish ex-Jesuit philosopher, Kazimierz Łyszczyński, author of a manuscript treatise, De non existentia Dei (On the Non-existence of God), was accused of atheism by a priest who was his debtor, was convicted, and was executed in most brutal fashion.
Wolff's doctrine was brought to Warsaw in 1740 by the Theatine, Portalupi; from 1743, its chief Polish champion was Wawrzyniec Mitzler de Kolof (1711–78), court physician to August III.
And in applying Kantian ideas to the natural sciences, he did something new that would not be undertaken until much later by Johannes Müller, Hermann Ludwig Ferdinand von Helmholtz and other famous scientists of the nineteenth century.
At the beginning of the nineteenth century, the Scottish School of Common Sense held sway in most European countries—in Britain till mid-century, and nearly as long in France.
"[40] An analogous position, shunning both positivism and metaphysical speculation, affined to the Scots but linked in some features to Kantian critique, was held in the period before the November 1830 Uprising by virtually all the university professors in Poland: in Wilno, by Dowgird; in Kraków, by Józef Emanuel Jankowski (1790–1847); and in Warsaw, by Adam Ignacy Zabellewicz (1784–1831) and Krystyn Lach-Szyrma (1791–1866).
[44] An important role in the Messianist movement was also played by the Polish Romantic poets, Adam Mickiewicz (1798–1855), Juliusz Słowacki (1809–49) and Zygmunt Krasiński (1812–59), as well as by religious activists such as Andrzej Towiański (1799–1878).
[50] The disastrous outcome of the January 1863 Uprising had produced a distrust of romanticism, an aversion to ideals and illusions, and turned the search for redemption toward sober thought and work directed at realistic goals.
The pioneers of the Warsaw Positivism were natural scientists and physicians rather than philosophers, and still more so journalists and men of letters: Aleksander Świętochowski (1849–1938), Piotr Chmielowski (1848–1904), Adolf Dygasiński (1839–1902),[54] Bolesław Prus (1847–1912).
About 1910 the small number of professionally trained philosophers increased sharply, as individuals returned who had been inspired by Mahrburg's underground lectures to study philosophy in Austrian-ruled Lwów and Kraków or abroad.
[60] There was growing interest in western philosophical currents, and much discussion of Pragmatism and Bergsonism, psychoanalysis, Henri Poincaré's Conventionalism, Edmund Husserl's Phenomenology, the Marburg School, and the social-science methodologies of Wilhelm Dilthey and Heinrich Rickert.
The Kraków school, true to tradition, showed an eminently historical character and produced a medievalist of world renown, Father Konstanty Michalski (1879–1947).
The first of their pupils to achieve eminence, even before World War II, was Alfred Tarski (1902–83),[68] from 1939 in the United States, where he became a professor at the University of California, Berkeley.
At Kraków also, and later at Lwów, logic studies were conducted by Leon Chwistek (1884–1944), a multi-faceted and somewhat eccentric thinker—mathematician, philosopher, esthetician, painter—whose name came to be associated popularly with his concept of "plural realities.
This, and contemporaneous sociopolitical currents, stimulated Leszek Kołakowski (1927–2009), writing in exile, to publish influential critiques of Marxist theory and communist practice.
