Thanks for this post.
Over the weekend, the White House ordered the arrest of Mahmoud Khalil, an American permanent resident with an American wife, because he was a leader of pro-Palestinian protests at Columbia University. Khalil might have his green card canceled for his role in these protests.
Although it might not get to this point, it’s not hard to imagine the White House eventually operating on a new, looser definition of treason in which “aid and comfort to the enemy” could include words that Trump or others in his admin don’t like. (They probably can’t legally redefine treason, but that might not matter since Trump has already shown he can enforce the law as he wants the law to be as opposed to enforcing the law as it is. Khalil is an example of this, as he might have his green card revoked without it going through an immigration court, which is the required process.)
The Trump admin has a list of universities it might financially punish for allowing Palestinian protests, which include top universities in New York and California, and it’s freezing/cutting funding for science research through universities in the US. Even non-science PhD programs in the US are reducing their budgets as a result.
The last point is probably the most obviously relevant for EAs right now, especially if they are deciding between studying at a US university or in another country—although anyone who cares about democracy and freedom of speech has reason to worry.
“So, for instance, suppose you take a baby and hit it with great force with a hammer. Moral realism says: 1. You’re doing something wrong.”
Moral realism doesn’t say that hitting a baby with a hammer is wrong. Moral realism entails that there is some fact about the morality of hitting a baby with a hammer. Probably, that moral fact is that it is wrong to do this, but moral realism is not a theory about specific moral facts. It’s a theory that moral facts are possible.
This is a pedantic point, but the more commitments you unnecessarily build into moral realism, the more likely someone is to reject it. Someone might be open to there being moral facts, and yet believe that the wrongness of torturing babies isn’t one of these facts. If someone like that accepted your claim that moral realists necessarily believe it is wrong to torture babies, they might think, “Oh, I guess I’m not a moral realist then.” The belief that it’s wrong to torture babies is a promising contender for one of the world’s most popular moral beliefs. Still, the less you commit the moral realist to, the more plausible moral realism is going to seem.
