Politics.
It was a field that Samuel didn't really take pleasure in engrossing himself with. Samuel didn't like politicians for their sloppy sales talk, bewitching people without discretion, and pretending to know things that are beyond their realm of knowledge.
Samuel hated people who try to pretend to know things more than they actually do.
And politicians are the epitome of that.
It wasn't that Samuel was apolitical or hated the government, he just disliked how all of it worked. All his life he dedicated himself to sciences, trying to put his good memory to good use. With constant research, he was able to stop himself from insanity. Focusing on other things kept himself at bay from arbitrary human interactions.
