You are far braver than I. Kant is the last author I would attempt to read in German.
polemarchos wrote:ius impune occidendi and fiat experimentum in corpore vili
Where are they from?
The first, let experiment be made on a worthless body, probably comes from a Latin translation of a medical work. The second, the right to kill with impunity, may come from medieval legal literature -- I've never heard the phrase before.
Does it mean: according to the principle that the experiment should be done in the worthless body (so cannot in the human body), there is nobody (barber-surgeon) has the right (law) that he could kill a person (by his poor operation) while does not have to be punished?
I feel unsure about this. What's Afteraezte
? Do you mean Affenärzte
, which I assume to be something like "quack-doctor"? In any case, I think the parenthetical part points out that there is no right to kill with impunity, but there is a principle that experiment can be made on a worthless body. On can train on corpora vilia
so as to avoid killing anyone in actual practice, which is a legitimate concern of government.
