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

At the time, there were major successes and advances in the sciences (for example, Isaac Newton, Carl Friedrich Gauss, and Robert Boyle) using reason and logic. But this stood in sharp contrast to the scepticism and lack of agreement or progress in empiricist philosophy.

Kant’s magnum opus, the Critique of Pure Reason (Kritik der reinen Vernunft, 1781), aimed to unite reason with experience to move beyond what he took to be failures of traditional philosophy and metaphysics. He hoped to end an age of speculation where objects outside experience were used to support what he saw as futile theories, while opposing the scepticism of thinkers such as Descartes, Berkeley and Hume.
