Stanisław Leśniewski — człowiek, uczony. Uwagi na marginesie książki Jacka Jadackiego "Stanisław Leśniewski. Geniusz logiki"
I discuss Jacek Jadacki’s recent book, Stanisław Leśniewski: geniusz logiki (Stanisław Leśniewski: A Genius of Logic). The book presents the scholar and his work from the point of view of the people who knew him. They describe both his views and his personality. It is worth noting that not all the accounts are favorable. In the last chapter, Jadacki presents his own survey of Leśniewski’s achievements.
