Philosopher
Immanuel Kant
1724–1804
Argued that the mind actively structures experience, reconciling rationalism and empiricism, and grounded morality in the rational will.

Kant said that reading Hume woke him from his “dogmatic slumber”. In the Critique of Pure Reason he argued that space, time and categories such as causality are not learned from experience but are forms the mind itself brings to it — so we can have certain knowledge of the world as it appears to us, though not of things as they are in themselves.
In ethics he held that the moral law is one that reason gives itself: act only on principles that you could will to be universal laws.
