Immanuel Kant was a German philosopher from Königsberg in East Prussia (now Kaliningrad, Russia). He is regarded as one of the most influential thinkers of modern Europe and the last major philosopher of the Enlightenment.
Kant defined the Enlightenment, in the essay "Answering the Question: What is Enlightenment?", as an age shaped by the motto, "Dare to know" (latin: Sapere aude). This involved thinking autonomously, free of the dictates of external authority. Kant's work served as a bridge between the Rationalist and Empiricist traditions of the 18th century. He had a decisive impact on the Romantic and German Idealist philosophies of the 19th century. His work has also been a starting point for many 20th century philosophers.
