Marcin Śmiglecki
Marcin Śmiglecki (Latin: Martinus Smiglecius or Leopolitanus; Lithuanian: Martynas Smigleckis) was a Polish Jesuit philosopher and logician born on 11 November 1564 in Lwów (now Lviv, Ukraine). He used several names over his life, including Lwowczyk, Leopolitanus, and later Śmiglecki or Smiglecius after the town of Śmigiel, his family’s origin. He studied at a Jesuit school in Pułtusk and then in Rome, where he joined the Jesuits in 1581; his education was financed by the statesman Jan Zamojski.
Śmiglecki earned a master’s degree in philosophy and a doctorate in theology at the Academy of Vilnius, where he also taught. In 1599 he took part in a public disputation with Protestant scholars Marcin Janicki and Daniel Mikołajewski, recorded by Martin Gratian Gertich.
In the last twenty years of his life he taught at Jesuit colleges in Pułtusk, Poznań, Kraków and Kalisz. He died in Kalisz on 26 or 28 July 1618.
His main works include Logica, first published in 1618 in Ingolstadt and reprinted many times, including editions in Oxford in 1634, 1638 and 1658, where it was used as a textbook. The book drew on the ideas of Gregory of Rimini and explored mental propositions.
Śmiglecki’s influence as a textbook author survived in a satirical poem The Logicians Refuted, sometimes attributed to Jonathan Swift or Oliver Goldsmith. In a contemporary debate he sided with Benedict Pereira against Giuseppe Biancani over the status of mathematics in physics, arguing that mathematics has an important role in science.
