For the most part I found this section of Kant’s writing to be more enjoyable as well as more understandable. His discussion of “duties” in each of the contexts he uses make the distinctions very clearly. I especially appreciated the explanation of a man’s duty to himself. Kant’s point that the idea of duty to oneself involves a contradiction was a point I myself would have raised had he not addressed it first.
I had a bit of difficulty with the concept of “defiling oneself by lust.” Kant made a point about couples who are at the time pregnant or incapable of procreating and their inability or lack of desire to work toward procreation that I found rather confusing.
When Kant talked about a man’s “duty to himself as his own innate judge,” I was able to understand his explanation that there is as a result of being one’s own judge, no actual duty in this situation as a man’s obligations to himself become no obligation at all.
Kant’s discussions of respect was also clear, as were his explanations of arrogance, and ridicule. However, I found defamation to be more complex and had difficulties comprehending.
I especially enjoyed the section on friendship.
