Johann Gottlieb Fichte

German Idealism · Europe · 1762 to 1814

German philosopher who built on Kant by making the free, self-positing act of the subject the starting point of everything.

What it is

Johann Gottlieb Fichte (1762 to 1814) was a German philosopher and one of the major figures between Kant and Hegel. Inspired by his reading of Kant, he built a rigorous system of his own that he called the Wissenschaftslehre, usually translated the Doctrine of Scientific Knowledge.

He tried to ground the whole of philosophy on one starting point, the free, self-active I, and from it to develop his accounts of knowledge, ethics, law and religion. He did most of this work at the University of Jena in the 1790s, where his lectures were very popular. A charge of atheism ended his time there.

The main ideas

  • The I as the starting point. Philosophy should begin not from a world of things but from the I that acts and knows. Everything else is understood from what this I does.
  • No unknowable thing-in-itself. He dropped Kant's idea of a thing in itself behind appearances that we cannot know, and held that the self and its activity are the starting point.
  • Freedom and striving. The I is free and always striving, and the world is the resistance against which it acts. Moral life is the task of acting freely within it.
  • A link in the chain. He stands between Kant and the systems of Schelling and Hegel, who took up and changed his central insight.

What it looks like in practice

Picture someone who feels that life simply happens to them, and who is asked instead to see each obstacle as the thing against which they decide who to be. Fichte's view makes the obstacle the field of freedom, not the cause of the person. This is an illustration of the idea, not a quotation.

Books and moments

  • The Wissenschaftslehre is his main system, set out in several versions.
  • The atheism controversy (1798 to 1799) followed an essay of his on belief in a divine governance of the world, and cost him his post at Jena.
  • Addresses to the German Nation are lectures from the Berlin years that are remembered for their appeal to national education.

Questions and criticism

  • Does the I create the world? Critics read him as saying that everything comes from the self, and he insisted that he meant something more modest. Readers still disagree.
  • Is a philosophy built from one point too tight? His effort to derive everything from the I is admired for its rigour and questioned for its narrowness.
  • Were the Addresses nationalist? The lectures have been read both as a call for education and as an early form of nationalism, and the reading remains disputed.

Close neighbours

He followed Kant, and Schelling and Hegel built on him in turn. The pages on Kant, Hegel and Schelling show the chain from critical philosophy to German idealism.
