German philosophy

German philosophy refers to philosophy written in German or by German philosophers. It started in the 17th century during the Age of Enlightenment, from Leibniz and Wolff through Kant, Schelling, Fichte, Hegel, Schopenhauer, Marx, Engels, and into the times of Nietzsche and Wittgenstein.
17th century.
The philosophy that dominated this century was the school of German philosopher and mathematican Gottfred Leibniz, later expanded by his follower, Christian Wolff. Leibniz thought that knowledge comes from reason alone.
18th century.
On the wake of the Enlightenment, a new philosophy called "critical philosophy" developed in Germany. It combined the ideals of philosophers Jean-Jacques Rousseau (1712-1778) of France and Switzerland and David Hume (1711-1776) of Scotland, and rationalism and empiricism. The founder of this school was Immanuel Kant. He published three "critiques", the most revolutionary being "Critique of Pure Reason" (1781), the other two being, "Critique of Practical Reason" and "Critique of Judgement". Two followers of Kant, Schelling and Fichte, thought that Kant's system had some errors and sought to improve it. A third philosopher, Hegel (1770-1831), developed his own kind of German idealism. His books are often difficult to read, and his ideas influenced many people, including those who agreed with him, and those who did not.
