These modes became somewhat of a rule first for Socrates, and later for his disciple, Plato. However, Descartes and Voltaire slightly modified those traditions in order to adjust the rationalities they wrote about to the needs and expectations of their contemporaries. Voltaire negated, among other things, the rationality of Descartes’ philosophy, but there were also a significant number of critics before him who expressed similar opinions, such as Leibniz or Kant.plArtykuł
