Introduction to the Metaphysic of Morals

Immanuel Kant (22 April 1724 – 12 February 1804) was a German philosopher from Königsberg (today Kaliningrad of Russia), researching, lecturing and writing on philosophy and anthropology during and at the end of the 18th Century Enlightenment.

In Kant’s essay “Answering the Question: What is Enlightenment?”, Kant defined the Enlightenment as an age shaped by the Latin motto Sapere aude ("Dare to Know"). Kant maintained that one ought to think autonomously, free of the dictates of external authority. His work reconciled many of the differences 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, and his work has also been a starting point for many 20th century philosophers.
