About this source
What it is
These are eleven short notes written by Karl Marx in 1845 as an outline for the first chapter of The German Ideology. They respond to the ideas of the philosopher Ludwig Feuerbach and were never published in Marx's lifetime, first appearing in print in 1888 thanks to Friedrich Engels.
Why it matters
The theses mark Marx's break from the Young Hegelian philosophers he had once admired. Its final line, insisting that philosophy's point is to change the world rather than just interpret it, became one of Marx's most famous statements and is engraved on his tombstone, showing how central the idea of practical action was to his thought.
Look closer
- Why might Marx have written these as short numbered notes rather than a full essay?
- What does the final thesis suggest about the relationship between thinking and acting?
- Why do you think these notes stayed unpublished for so long?
