On Volcanoes on the Moon
Kant discusses a lunar light observed by Herschel and Aepinus's volcanic explanation of lunar relief. An observation compatible with a hypothesis does not establish every conclusion attached to it.
Understanding the text
The 1785 article responds to astronomical reports circulating through scholars and periodicals; its explanations predate modern lunar geology.
Key points
- 01
Observation
What appears in an instrument must be distinguished from identifying the phenomenon as a volcano.
- 02
Explanation
Even an active volcano would not establish that all lunar surface formations have the same origin.
- 03
Priority
Debates about who first proposed a hypothesis cannot replace evaluating its supporting arguments.
How to read it
Separate reported observation, analogy with Earth and the disputed geological generalization.
